Question 1: A city council argues that installing a new network of bicycle lanes will improve public health. Their reasoning is that the lanes will encourage more residents to cycle, leading to increased physical activity.
- The cost of constructing the new lanes will be offset by revenue from bicycle registration fees.
- A survey indicates that a majority of residents support the construction of new bicycle lanes.
- The city's public transportation system is currently operating at maximum capacity.
- A significant number of residents who do not currently cycle have stated that the primary reason is a lack of safe bicycle lanes. (Correct answer)
Correct answer: A significant number of residents who do not currently cycle have stated that the primary reason is a lack of safe bicycle lanes.
The correct answer directly strengthens the causal link in the argument. The council's reasoning depends on the assumption that building lanes will cause people to cycle more. This statement provides evidence that a lack of safe lanes is the actual barrier preventing people from cycling, thus reinforcing the idea that removing this barrier will lead to the desired outcome.
Question 2: Read the following statements: 1. All members of the finance committee have a background in economics. 2. Dr. Evans is a member of the finance committee. 3. All individuals with a background in economics understand monetary policy. Based only on the statements above, which of the following conclusions must be true?
- All committee members understand monetary policy.
- Dr. Evans understands monetary policy. (Correct answer)
- Only economists are on the finance committee.
- Dr. Evans is the head of the finance committee.
Correct answer: Dr. Evans understands monetary policy.
This is a question of deductive reasoning. From statement 2, we know Dr. Evans is on the committee. From statement 1, we know all committee members have a background in economics, so Dr. Evans must have one. From statement 3, we know all individuals with that background understand monetary policy. Therefore, it logically follows that Dr. Evans must understand monetary policy.
Question 3: A marketing campaign for 'Vita-Boost' cereal claims: 'A recent study showed that people who eat Vita-Boost for breakfast have 20% more energy throughout the day.' What is the primary flaw in using this claim to prove the cereal's effectiveness?
- The claim does not specify what 'energy' is or how it was measured.
- The claim does not mention the nutritional content of the cereal.
- The campaign fails to show that the study was peer-reviewed.
- The study shows a correlation, but it does not prove that the cereal caused the increase in energy. (Correct answer)
Correct answer: The study shows a correlation, but it does not prove that the cereal caused the increase in energy.
This is a classic example of confusing correlation with causation. The study shows a relationship between two things (eating the cereal and having more energy), but it does not prove that the cereal is the cause of the energy increase. Other factors, such as the overall lifestyle of people who choose this cereal, could be responsible for the higher energy levels.
Question 4: Argument: 'To succeed in modern business, one must be willing to take significant risks. Therefore, a cautious and methodical approach to business management is the primary obstacle to achieving success.' The conclusion of this argument depends on which of the following assumptions?
- All successful businesses were built on significant risks.
- A cautious and methodical approach is mutually exclusive with taking significant risks. (Correct answer)
- Business success is defined purely by financial profit.
- Most new businesses fail within the first five years.
Correct answer: A cautious and methodical approach is mutually exclusive with taking significant risks.
The argument sets up a false dichotomy. It concludes that because risk-taking is necessary, a cautious approach must be an obstacle. This only holds true if one assumes that a person cannot be both cautious/methodical AND a risk-taker. It's possible to take calculated, well-planned risks, which would invalidate the argument's conclusion. The argument assumes these two approaches cannot coexist.
Question 5: A manager reviews the weekly performance of two employees, Sam and Pat. Sam completed 15 tasks and made 3 errors. Pat completed 10 tasks and made 1 error. The manager concludes that Pat is the more reliable employee. Which piece of additional information would most seriously weaken the manager's conclusion?
- Sam has been with the company for five years, while Pat was hired six months ago.
- The tasks completed by Sam were significantly more complex and difficult than those completed by Pat. (Correct answer)
- Pat and Sam work in different departments and are evaluated on different performance metrics.
- The company recently implemented a new software system that both employees are still learning.
Correct answer: The tasks completed by Sam were significantly more complex and difficult than those completed by Pat.
The manager's conclusion is based on a simple comparison of task and error counts. If Sam's tasks were much harder, his higher error count (and higher task completion) might actually represent a better performance than Pat's fewer errors on simpler tasks. This information directly challenges the fairness of the manager's comparison and thus weakens the conclusion drawn from it.
Question 6: Which of the following sentences expresses a fact rather than an opinion?
- The film's runtime was an excessive three hours, which made the story feel bloated.
- The government should allocate more resources to developing renewable energy sources.
- The painting is undoubtedly the artist's most profound and moving work.
- The company's annual report states that profits increased by 7% in the last fiscal year. (Correct answer)
Correct answer: The company's annual report states that profits increased by 7% in the last fiscal year.
A fact is a statement that can be objectively verified. The statement about the company's annual report can be proven true or false by examining that document. The other options contain subjective words ('excessive', 'should', 'profound') that express personal judgments, beliefs, or interpretations, making them opinions.
