Reading Comprehension Fact, Opinion and Author's Bias — Questions and Answers

Question 1: "The Amazon rainforest covers approximately 5.5 million square kilometers and produces about 20% of the world's oxygen. It is clearly the most important ecosystem on Earth and must be protected above all others." Question: Which sentence from the passage states a fact?

The Amazon rainforest covers approximately 5.5 million square kilometers and produces about 20% of the world's oxygen. (Correct answer)
It is clearly the most important ecosystem on Earth.
It must be protected above all others.
Both the second and third sentences state facts.

Correct answer: The Amazon rainforest covers approximately 5.5 million square kilometers and produces about 20% of the world's oxygen.

The size and oxygen production figures are measurable and verifiable; 'most important' and 'must be protected' express the author's values and judgments.

Question 2: A restaurant review reads: "The new downtown bistro seats 80 guests across two floors. The pasta dishes are absolutely divine, and the dessert menu is the most creative in the city. Reservations are required on weekends." Question: Which statement is an opinion?

The pasta dishes are absolutely divine. (Correct answer)
The bistro seats 80 guests across two floors.
Reservations are required on weekends.
The bistro has two floors.

Correct answer: The pasta dishes are absolutely divine.

'Absolutely divine' is a subjective taste judgment that cannot be independently verified, making it an opinion rather than a fact.

Question 3: A political speech states: "Our city's unemployment rate fell from 8% to 5% over the past two years. This is proof that our economic policies are working brilliantly, and anyone who disagrees simply does not understand economics." Question: What bias does the author reveal?

The author presents the data selectively to credit only their own policies and dismisses critics as ignorant. (Correct answer)
The author fairly considers multiple causes for the unemployment drop.
The author is biased against economic policies in general.
The author presents a factual, balanced analysis.

Correct answer: The author presents the data selectively to credit only their own policies and dismisses critics as ignorant.

The author attributes the drop solely to 'our policies' without considering other factors, and dismisses dissent with an ad hominem attack, revealing a self-serving bias.

Question 4: "Mount Everest stands 8,849 meters above sea level, making it the highest mountain on Earth. Every serious mountaineer should attempt to summit it at least once in their lifetime." Question: Which part of the passage is a fact?

Mount Everest stands 8,849 meters above sea level, making it the highest mountain on Earth. (Correct answer)
Every serious mountaineer should attempt to summit it.
Both sentences state facts.
Neither sentence states a verifiable fact.

Correct answer: Mount Everest stands 8,849 meters above sea level, making it the highest mountain on Earth.

The height and ranking of Everest are measurable and documented; the recommendation that 'every serious mountaineer should summit it' is a prescriptive opinion.

Question 5: A newspaper article about a new park reads: "The city council approved a $3 million budget for the park project. Residents in the area are thrilled about the new green space, while business owners worry about construction disrupting traffic for 18 months." Question: What technique does the author use to maintain balance?

The author presents both a positive perspective (residents) and a negative concern (business owners). (Correct answer)
The author uses only facts and no opinions.
The author sides with the business owners' concern.
The author avoids mentioning the cost to remain neutral.

Correct answer: The author presents both a positive perspective (residents) and a negative concern (business owners).

By voicing both residents' enthusiasm and business owners' concerns, the author represents two opposing viewpoints, which is a hallmark of balanced reporting.

Question 6: A magazine article states: "Electric vehicles produce zero direct emissions and are cheaper to operate than gasoline cars over a ten-year period. They are undoubtedly the only reasonable choice for responsible car buyers today." Question: Which statement is an opinion?

They are undoubtedly the only reasonable choice for responsible car buyers today. (Correct answer)
Electric vehicles produce zero direct emissions.
They are cheaper to operate than gasoline cars over a ten-year period.
Electric vehicles exist as an alternative to gasoline cars.

Correct answer: They are undoubtedly the only reasonable choice for responsible car buyers today.

'Undoubtedly the only reasonable choice' is a strong prescriptive claim that cannot be verified; it reflects the author's viewpoint, not a measurable fact.

Question 7: A letter to the editor reads: "Local crime statistics show a 10% decrease in burglaries this year. Our new police chief deserves full credit for this improvement — she is clearly the best law enforcement leader this town has ever seen." Question: What bias does this passage show?

The author attributes the entire crime decrease to the police chief without considering other possible factors. (Correct answer)
The author is biased against the police chief.
The author fairly explains all causes of the crime decrease.
The author is biased against reporting crime statistics.

Correct answer: The author attributes the entire crime decrease to the police chief without considering other possible factors.

Crime decreases can result from many factors (economic conditions, community programs, etc.); crediting only the police chief and calling her the best ever shows uncritical admiration bias.

Question 8: A travel blog entry reads: "The Colosseum in Rome was completed in 80 AD and could hold up to 80,000 spectators. It is without question the most awe-inspiring structure humans have ever built." Question: Which sentence states a fact?

The Colosseum in Rome was completed in 80 AD and could hold up to 80,000 spectators. (Correct answer)
It is without question the most awe-inspiring structure humans have ever built.
Both sentences state facts.
Neither sentence states a verifiable fact.

Correct answer: The Colosseum in Rome was completed in 80 AD and could hold up to 80,000 spectators.

Completion date and seating capacity are historical facts that can be verified; 'most awe-inspiring' is a subjective evaluation.

Question 9: A product review states: "This blender has a 1,500-watt motor and a 64-ounce container. It is by far the best blender on the market and anyone who buys any other brand is wasting their money." Question: Which part of the review is an opinion?

It is by far the best blender on the market and anyone who buys any other brand is wasting their money. (Correct answer)
This blender has a 1,500-watt motor.
It has a 64-ounce container.
The blender was manufactured by a company.

Correct answer: It is by far the best blender on the market and anyone who buys any other brand is wasting their money.

'Best on the market' and 'wasting their money' are subjective judgments that depend on personal needs and comparisons; they cannot be objectively verified.

Question 10: A science textbook reads: "Vaccines work by introducing a weakened or inactivated form of a pathogen to stimulate the immune system. Some critics claim vaccines are unnecessary because modern hygiene alone can prevent most diseases — this belief is not supported by scientific evidence." Question: What is the author's stance?

The author supports vaccines and views the anti-vaccine claim as scientifically unfounded. (Correct answer)
The author is neutral and presents both sides equally.
The author is biased against vaccines and favors hygiene.
The author avoids making any judgment about vaccines.

Correct answer: The author supports vaccines and views the anti-vaccine claim as scientifically unfounded.

By stating that the anti-vaccine claim 'is not supported by scientific evidence,' the author clearly takes a pro-vaccine position while framing the opposing view as wrong.

Question 11: "The International Space Station has been continuously occupied since November 2000 and orbits Earth approximately 16 times per day. Space exploration is an expensive waste of resources that could better serve people here on Earth." Question: Which sentence is an opinion?

Space exploration is an expensive waste of resources that could better serve people here on Earth. (Correct answer)
The International Space Station has been continuously occupied since November 2000.
The ISS orbits Earth approximately 16 times per day.
The ISS is in orbit around Earth.

Correct answer: Space exploration is an expensive waste of resources that could better serve people here on Earth.

'Expensive waste' and 'could better serve' are value judgments about priorities; reasonable people disagree, making this an opinion rather than a fact.

Question 12: A news article about a local election reads: "Candidate A received 54% of the vote and won the mayoral race. She campaigned on reducing taxes and expanding public transit. Her landslide victory proves that voters overwhelmingly endorse her entire platform." Question: Where does the author introduce a biased interpretation?

Calling 54% a 'landslide' and claiming it 'proves' endorsement of her entire platform overstates the meaning of the result. (Correct answer)
Stating that she received 54% of the vote.
Noting that she campaigned on taxes and transit.
Saying she won the mayoral race.

Correct answer: Calling 54% a 'landslide' and claiming it 'proves' endorsement of her entire platform overstates the meaning of the result.

54% is a modest majority, not a 'landslide'; voters may support a candidate without endorsing every policy, so the word choices overstate and editorialize the outcome.

Question 13: An environmental report states: "Global average temperatures have risen by approximately 1.1°C since pre-industrial times. Fossil fuel combustion is the primary driver of this change according to 97% of climate scientists. Transitioning to renewable energy is the morally correct choice for all nations." Question: Which sentence is an opinion?

Transitioning to renewable energy is the morally correct choice for all nations. (Correct answer)
Global average temperatures have risen by approximately 1.1°C since pre-industrial times.
Fossil fuel combustion is the primary driver according to 97% of climate scientists.
Climate scientists have issued reports on global temperatures.

Correct answer: Transitioning to renewable energy is the morally correct choice for all nations.

'Morally correct choice' introduces an ethical judgment that goes beyond scientific data and reflects the author's values rather than a measurable fact.

Question 14: A book review reads: "The novel is set in 1920s Paris and features a cast of expatriate American writers. The author uses long, meandering sentences that make the book nearly unreadable. However, the historical research behind the novel is thorough." Question: How would you characterize this review?

It mixes facts (setting, cast type, historical research quality) with the reviewer's opinions (sentence style, readability). (Correct answer)
It contains only facts about the novel.
It contains only the reviewer's opinions.
It is entirely biased in favor of the novel.

Correct answer: It mixes facts (setting, cast type, historical research quality) with the reviewer's opinions (sentence style, readability).

Setting and cast type are verifiable; 'nearly unreadable' and 'thorough research' are evaluative judgments that reflect the reviewer's perspective.

Question 15: "The human brain contains approximately 86 billion neurons. Scientists who study the brain are engaged in the most fascinating field of research in existence today." Question: Which sentence states a fact?

The human brain contains approximately 86 billion neurons. (Correct answer)
Scientists who study the brain are engaged in the most fascinating field of research in existence today.
Both sentences state facts.
Neither sentence can be verified.

Correct answer: The human brain contains approximately 86 billion neurons.

The neuron count is an estimated figure based on scientific counting methods; 'most fascinating field' is a subjective ranking that varies by individual interest.

Question 16: A social media post reads: "A recent survey found that 68% of Americans support stricter gun control laws. This majority view should obviously become law immediately, and those who oppose it are clearly out of touch with the American public." Question: What bias does the author show?

The author uses the survey to push a specific policy conclusion and dismisses opposing views as out of touch. (Correct answer)
The author is biased against surveys and statistics.
The author fairly represents both sides of the gun debate.
The author is biased in favor of gun rights.

Correct answer: The author uses the survey to push a specific policy conclusion and dismisses opposing views as out of touch.

Moving from 'a majority support this' to 'it should obviously become law immediately' is a logical leap, and calling opponents 'out of touch' dismisses them without engaging their arguments.

Question 17: A history textbook states: "The Great Wall of China was built over many centuries, with major construction occurring during the Ming dynasty (1368–1644). It stretches approximately 21,000 kilometers. It is the greatest engineering achievement in human history." Question: Which sentence is an opinion?

It is the greatest engineering achievement in human history. (Correct answer)
The Great Wall was built over many centuries.
Major construction occurred during the Ming dynasty.
It stretches approximately 21,000 kilometers.

Correct answer: It is the greatest engineering achievement in human history.

'Greatest engineering achievement in human history' is a superlative judgment that requires comparing all human achievements — a subjective ranking, not a verifiable fact.

Question 18: An editorial reads: "Studies show that students who attend schools with smaller class sizes score, on average, 12% higher on standardized tests. Clearly, every school district in the nation must immediately reduce class sizes regardless of cost." Question: Where does the author's bias appear?

The author leaps from a research finding to a sweeping policy prescription ('every district must') that ignores financial constraints. (Correct answer)
The author is biased against standardized testing.
The author uses the study to argue against reducing class sizes.
The author presents a perfectly balanced argument.

Correct answer: The author leaps from a research finding to a sweeping policy prescription ('every district must') that ignores financial constraints.

The study shows a correlation, but the author's use of 'clearly' and 'must immediately… regardless of cost' imposes a one-size-fits-all solution without acknowledging trade-offs.

Question 19: "The first commercial jet airliner, the de Havilland Comet, entered service in 1952. Flying is statistically the safest form of long-distance travel. Anyone who is afraid to fly is simply being irrational." Question: Which sentence is an opinion?

Anyone who is afraid to fly is simply being irrational. (Correct answer)
The de Havilland Comet entered service in 1952.
Flying is statistically the safest form of long-distance travel.
The de Havilland Comet was a jet airliner.

Correct answer: Anyone who is afraid to fly is simply being irrational.

Calling a fear 'irrational' is a judgment about other people's emotional responses; the statistics and historical date are verifiable claims.

Question 20: A food magazine article states: "Dark chocolate contains flavonoids that may support heart health. It has between 50% and 90% cacao content. Dark chocolate is undeniably the superior choice for any health-conscious person." Question: Which sentence is an opinion?

Dark chocolate is undeniably the superior choice for any health-conscious person. (Correct answer)
Dark chocolate contains flavonoids that may support heart health.
It has between 50% and 90% cacao content.
Dark chocolate exists as a distinct food product.

Correct answer: Dark chocolate is undeniably the superior choice for any health-conscious person.

'Undeniably the superior choice' is a broad evaluative judgment ignoring that individual health needs and taste preferences vary widely.

Question 21: A company press release reads: "Our new smartphone features a 200-megapixel camera and a 5,000 mAh battery. Independent lab tests confirmed it lasted 18 hours on a single charge. It is the most revolutionary phone ever released and will change the world forever." Question: What is true about the last sentence?

It is a promotional opinion that exaggerates the phone's significance beyond what facts can support. (Correct answer)
It is a fact supported by the lab test results.
It is a fact about the phone's technical specifications.
It is a neutral description of the phone's design.

Correct answer: It is a promotional opinion that exaggerates the phone's significance beyond what facts can support.

'Most revolutionary ever' and 'change the world forever' are hyperbolic marketing claims that express the company's self-interest rather than verifiable truths.

Question 22: "Shakespeare wrote 37 plays and 154 sonnets during his lifetime. His works are the most beautiful and profound pieces of literature ever written in the English language." Question: Which sentence is a fact?

Shakespeare wrote 37 plays and 154 sonnets during his lifetime. (Correct answer)
His works are the most beautiful and profound pieces of literature ever written in English.
Both sentences are facts.
Neither sentence is verifiable.

Correct answer: Shakespeare wrote 37 plays and 154 sonnets during his lifetime.

The number of plays and sonnets is a documented, countable fact; 'most beautiful and profound ever written' is a superlative aesthetic judgment.

Question 23: An op-ed about immigration reads: "Immigration levels to this country have doubled over the past decade. Immigrants are taking jobs from native-born workers and draining public resources. Stricter border controls are the only sensible solution." Question: What bias does the author display?

The author presents a negative view of immigration without acknowledging economic contributions immigrants make or alternative policy views. (Correct answer)
The author is biased in favor of immigration.
The author presents a balanced view of immigration policy.
The author is biased against border enforcement in general.

Correct answer: The author presents a negative view of immigration without acknowledging economic contributions immigrants make or alternative policy views.

The author uses negative framing ('taking jobs,' 'draining resources') without presenting counterevidence and calls one controversial policy 'the only sensible solution,' revealing anti-immigration bias.

Question 24: "The Eiffel Tower was completed in 1889 and stands 330 meters tall. It attracts about 7 million visitors each year. Paris is obviously the most romantic city in the world." Question: Which sentence is an opinion?

Paris is obviously the most romantic city in the world. (Correct answer)
The Eiffel Tower was completed in 1889 and stands 330 meters tall.
It attracts about 7 million visitors each year.
The Eiffel Tower is located in Paris.

Correct answer: Paris is obviously the most romantic city in the world.

'Most romantic city in the world' is a subjective ranking based on feelings; the tower's height, construction date, and visitor numbers are measurable.

Question 25: A health magazine states: "A 2024 study found that adults who sleep fewer than 6 hours per night have a 30% higher risk of cardiovascular disease. Getting enough sleep is the most important thing you can do for your health — far more important than diet or exercise." Question: Where does opinion appear?

Getting enough sleep is the most important thing — far more important than diet or exercise — is an opinion that ranks health factors subjectively. (Correct answer)
Adults who sleep fewer than 6 hours have a 30% higher cardiovascular risk is an opinion.
Both sentences are opinions.
Both sentences are facts.

Correct answer: Getting enough sleep is the most important thing — far more important than diet or exercise — is an opinion that ranks health factors subjectively.

The 30% risk increase comes from a study and is a measurable fact; ranking sleep as 'most important… far more than diet or exercise' is a value judgment unsupported by the study alone.

Question 26: A news report reads: "The city council voted 7–2 to approve the new stadium. Supporters argue it will create 2,000 construction jobs. Critics say the $500 million cost is too high given the city's underfunded schools." Question: What approach does this passage demonstrate?

Balanced reporting that presents both supporters' and critics' perspectives. (Correct answer)
Biased reporting that favors the stadium construction.
Biased reporting that opposes the stadium.
A report that contains no facts, only opinions.

Correct answer: Balanced reporting that presents both supporters' and critics' perspectives.

The report states the factual vote count and then presents both the pro side (jobs) and the con side (cost vs. schools), which is the hallmark of balanced journalism.

Question 27: A food blog post reads: "Avocados contain healthy monounsaturated fats and are rich in potassium. One medium avocado provides about 240 calories. Avocado toast is the greatest breakfast invention of the 21st century." Question: Which sentence is an opinion?

Avocado toast is the greatest breakfast invention of the 21st century. (Correct answer)
Avocados contain healthy monounsaturated fats and are rich in potassium.
One medium avocado provides about 240 calories.
Avocados are a food product.

Correct answer: Avocado toast is the greatest breakfast invention of the 21st century.

'Greatest breakfast invention of the 21st century' is a hyperbolic, subjective ranking that reflects the author's enthusiasm rather than a measurable claim.

Question 28: An article about urban planning states: "Studies show that cities with more green spaces have lower rates of stress-related illness among residents. Adding parks and trees to urban environments is not only the right thing to do morally but is also the only acceptable course of action for city planners." Question: What shift occurs in the second sentence?

The author moves from evidence-based reporting to a prescriptive moral judgment that goes beyond what the studies prove. (Correct answer)
The author summarizes the study's findings accurately.
The author presents a factual policy recommendation.
The author shifts from opinion back to fact.

Correct answer: The author moves from evidence-based reporting to a prescriptive moral judgment that goes beyond what the studies prove.

The first sentence reports study findings; the second introduces 'morally right' and 'only acceptable' — value-laden language that prescribes action beyond what data alone can mandate.

"The Amazon rainforest covers approximately 5.5 million square kilometers and produces about 20% of the world's oxygen.
It is clearly the most important ecosystem on Earth and must be protected above all others." Question: Which sentence from the passage states a fact?
