ISAT - International Student Admissions Reading Comprehension: Main Idea Questions and Answers

Question 1

Read the following passage and answer the question.

The proliferation of 'fast fashion'—inexpensive, stylish clothing produced rapidly by mass-market retailers in response to the latest trends—has fundamentally altered the textile industry and consumer behavior. While it makes fashion more accessible to a wider audience, the model's reliance on rapid production cycles and low-cost labor raises significant ethical and environmental concerns. Supply chains are often opaque, with documented instances of poor working conditions and inadequate wages. Environmentally, the industry is a major polluter, from the water-intensive cultivation of cotton to the use of synthetic dyes and the vast quantities of textile waste that end up in landfills. Critics argue that the transient nature of fast fashion encourages a 'disposable' culture, devaluing craftsmanship and sustainability.

What is the main idea of the passage?

Accepted Answer

The fast fashion model, despite democratizing style, is criticized for its significant negative ethical and environmental impacts.

Answer

The passage provides a balanced overview of fast fashion, acknowledging its benefit (making fashion accessible) before detailing its primary drawbacks (ethical and environmental concerns). Answer B encapsulates this central conflict, making it the main idea. Answer A is a supporting detail, focusing only on the environmental aspect. Answer C suggests an action not mentioned in the passage. Answer D focuses on a positive aspect without mentioning the significant criticisms that form the core of the text.

Question 2

Read the following passage and answer the question.

Urban heat islands are metropolitan areas that are significantly warmer than their surrounding rural areas due to human activities. The main cause is the modification of land surfaces, where natural vegetation is replaced by pavement, buildings, and other structures that absorb and retain more of the sun's heat. Waste heat generated by energy usage is a secondary contributor. This phenomenon can increase energy costs for cooling, elevate air pollution levels, and lead to heat-related illness and mortality. Mitigation strategies include increasing tree and vegetative cover, installing 'cool'—or reflective—roofs, and using cool pavements. Such measures can reduce temperatures, leading to energy savings and improved public health.

Which of the following best expresses the main idea of the passage?

Accepted Answer

Urban heat islands are a growing problem with health and economic consequences, but solutions exist to mitigate their effects.

Answer

This answer choice correctly summarizes the entire passage, which defines the problem (urban heat islands), outlines its causes and consequences (health, economic), and presents potential solutions. Answer A states only the primary cause, which is just one component of the passage. Answer C highlights a specific solution, making it too narrow. Answer D is an oversimplification and doesn't capture the full explanation provided in the text.

Question 3

Read the following scenario and answer the question.

A historian is analyzing the societal impact of the printing press in 15th-century Europe. Her research shows that while the technology was revolutionary, its initial effects were concentrated among a small, literate elite of scholars, clergy, and nobles. The mass production of texts did not immediately lead to widespread literacy. Instead, it first amplified existing intellectual and religious debates within established circles. Only over subsequent centuries, as costs decreased and vernacular languages were used more frequently, did the printing press become a true engine of mass communication and popular literacy. The historian concludes that the press's role as a democratizing force was an evolutionary process, not an instantaneous revolution.

What is the central argument of the historian's analysis?

Accepted Answer

The societal transformation brought by the printing press was gradual, initially affecting elites before leading to mass literacy over time.

Answer

This option accurately captures the historian's nuanced conclusion. It reflects the idea that the impact was not immediate or universal but evolved over time, starting with the elite and slowly expanding. Answer A is too restrictive and inaccurate. Answer B is related but is a supporting point rather than the main argument about the printing press itself. Answer C is a value judgment that the passage does not make.

Question 4

Read the following passage and answer the question.

Cognitive dissonance is the mental discomfort experienced by a person who holds two or more contradictory beliefs, ideas, or values, or is confronted by new information that conflicts with existing beliefs. When this discomfort arises, people are motivated to reduce it. They might change one or more of the attitudes or beliefs, acquire new information that outweighs the dissonant beliefs, or reduce the importance of the cognitions. For instance, a smoker who knows smoking is unhealthy may reduce dissonance by quitting, by downplaying the health risks ('It's not that bad'), or by justifying their behavior ('I need it to manage stress'). This drive to relieve internal inconsistency is a powerful motivator of human behavior and attitude change.

What is the primary purpose of this passage?

Accepted Answer

To define cognitive dissonance, explain how it arises, and describe the ways people resolve it.

Answer

The passage is structured as an expository text. It begins with a clear definition of cognitive dissonance, explains its cause (conflicting beliefs), and then details the various strategies people use to alleviate the resulting discomfort, providing an example for clarity. Answer C perfectly summarizes this structure and purpose. Answer A uses the example as the main idea. Answer B is too broad, as only one theory is discussed. Answer D describes a potential application of the concept but not the purpose of the passage itself.

Question 5

Read the following passage and answer the question.

The concept of 're-wilding' has gained traction in conservation circles as a method to restore and protect natural processes and core wilderness areas. It involves a spectrum of actions, from passive management where nature is allowed to take its own course, to the active reintroduction of keystone species that have been absent from an ecosystem. Proponents argue that re-wilding can increase biodiversity, create self-regulating ecosystems, and sequester carbon. However, the approach is not without its challenges. Reintroducing large predators can lead to conflicts with local farming communities, and the long-term outcomes of such large-scale ecological interventions are not always predictable. Successful implementation requires careful planning, scientific monitoring, and community engagement.

Which statement best captures the main idea of the passage?

Accepted Answer

Re-wilding is a promising conservation approach with significant benefits, but it also presents complex challenges that require careful management.

Answer

This choice provides a balanced summary of the passage, acknowledging both the positive aspects of re-wilding (its goals and benefits) and its difficulties (conflicts, unpredictability). The passage presents these two sides of the issue. Answer A is an extreme and unsupported claim. Answer B focuses on a specific challenge, which is a supporting detail, not the main idea. Answer D makes a comparison that is not supported by the passage.
