GCAT Reading Comprehension and Passage Analysis

Question 1

Read the passage and answer the question.

"Coral reefs occupy less than 1% of the ocean floor yet support approximately 25% of all marine species. Despite their ecological importance, rising ocean temperatures and acidification — both linked to climate change — are causing widespread bleaching events. Scientists estimate that over 50% of the world's coral reefs have been lost in the past three decades."

What is the main idea of this passage?

Accepted Answer

Coral reefs are biodiversity hotspots that face serious environmental threats

Answer

The passage introduces coral reefs' ecological value (supporting 25% of marine species) and then explains the threats causing their decline (temperature, acidification, bleaching). Both ideas together make option B the best summary of the passage's main point.

Question 2

Using the same coral reef passage, which conclusion is BEST supported by the information given?

Accepted Answer

A significant proportion of the world's coral reefs has already been lost

Answer

The passage states that over 50% of coral reefs have been lost in three decades — directly supporting option C. Option A overstates the prediction; option B contradicts the implied importance of reefs; option D is not mentioned in the passage.

Question 3

Read the passage and answer the question.

"The printing press, invented by Johannes Gutenberg around 1440, revolutionised the spread of information across Europe. By making books affordable and widely available, it accelerated literacy rates, challenged ecclesiastical control over knowledge, and played a pivotal role in the Protestant Reformation and the Scientific Revolution."

What does the passage suggest about the printing press?

Accepted Answer

It contributed to major intellectual and religious transformations in Europe

Answer

The passage directly states that the printing press 'played a pivotal role in the Protestant Reformation and the Scientific Revolution' and accelerated literacy — all pointing to widespread intellectual and religious transformation. The other options contradict or misrepresent the passage.

Question 4

Using the same printing press passage, the word 'pivotal' most nearly means:

Accepted Answer

Crucial

Answer

In context, 'pivotal' describes the degree of the printing press's role in the Reformation and Scientific Revolution. 'Crucial' (meaning critically important or central) best fits this meaning. 'Controversial' or 'incidental' would change the meaning of the sentence significantly.

Question 5

Read the passage and answer the question.

"Unlike introversion, which describes a preference for less stimulating environments, shyness involves anxiety or discomfort in social situations. A person can be introverted without being shy, and extroverts can also experience shyness. The two traits are frequently conflated but are psychologically distinct."

According to the passage, which statement is TRUE?

Accepted Answer

An introverted person may not experience social discomfort

Answer

The passage explicitly states 'A person can be introverted without being shy,' which directly supports option C. Options A and D are contradicted by the passage's central argument that the two traits are distinct. Option B is also contradicted — the passage says extroverts can be shy.
