ISAT - International Student Admissions Reading Comprehension: Main Idea Questions and Answers — 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?
- Fast fashion is a major cause of water pollution and textile waste.
- The fast fashion model, despite democratizing style, is criticized for its significant negative ethical and environmental impacts. (Correct answer)
- Consumers should boycott fast fashion retailers to promote sustainability.
- The textile industry has become more efficient due to fast fashion's production model.
Correct answer: The fast fashion model, despite democratizing style, is criticized for its significant negative ethical and environmental impacts.
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?
- The primary cause of urban heat islands is the replacement of natural land cover with artificial surfaces.
- Urban heat islands are a growing problem with health and economic consequences, but solutions exist to mitigate their effects. (Correct answer)
- Installing reflective roofs is the most effective strategy for combating the urban heat island effect.
- Urban areas are always warmer than rural areas because of industrial pollution.
Correct answer: Urban heat islands are a growing problem with health and economic consequences, but solutions exist to mitigate their effects.
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?
- The printing press was only useful to the clergy and nobility in the 15th century.
- The spread of literacy in Europe was a slower process than is commonly believed.
- The printing press was the single most important invention in European history.
- The societal transformation brought by the printing press was gradual, initially affecting elites before leading to mass literacy over time. (Correct answer)
Correct answer: The societal transformation brought by the printing press was gradual, initially affecting elites before leading to mass literacy over time.
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?
- To argue that smoking is a difficult habit to quit.
- To compare different psychological theories of motivation.
- To define cognitive dissonance, explain how it arises, and describe the ways people resolve it. (Correct answer)
- To persuade readers to align their actions with their beliefs.
Correct answer: To define cognitive dissonance, explain how it arises, and describe the ways people resolve it.
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?
- Re-wilding is the best and only way to solve the current biodiversity crisis.
- Reintroducing large predators is a controversial and often dangerous conservation strategy.
- Re-wilding is a promising conservation approach with significant benefits, but it also presents complex challenges that require careful management. (Correct answer)
- Passive management is a more effective re-wilding technique than reintroducing species.
Correct answer: Re-wilding is a promising conservation approach with significant benefits, but it also presents complex challenges that require careful management.
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.
Question 6: Read the following passage and answer the question. For centuries, the predominant model of memory viewed the mind as a kind of library or computer, where memories are stored as discrete, stable files to be retrieved when needed. However, contemporary neuroscience is advancing a different view: that memory is a fundamentally reconstructive process. Each time we recall an event, our brain does not simply 'replay' a recording. Instead, it actively rebuilds the memory, and this process can be influenced by our current emotional state, beliefs, and new information. This explains why memories can change or become distorted over time. Far from being a flaw, this flexibility allows us to integrate new experiences and learn, but it also makes our recollections malleable and susceptible to error. What is the central point of the passage?
- The traditional view of memory as a storage system is fundamentally flawed.
- Memories are unreliable and should not be trusted, especially in legal contexts.
- Modern neuroscience views memory not as a static retrieval system, but as an active, reconstructive process that is flexible yet fallible. (Correct answer)
- The brain's ability to learn is dependent on the malleability of memory.
Correct answer: Modern neuroscience views memory not as a static retrieval system, but as an active, reconstructive process that is flexible yet fallible.
This sentence best synthesizes the entire passage. It contrasts the old model with the new (retrieval vs. reconstructive), explains the nature of the new model (active, flexible), and notes its key consequence (fallibility). Answer A is part of the main idea but doesn't include the new theory. Answer B is an implication of the main idea, but not the idea itself. Answer D is a supporting detail that explains one benefit of memory's flexibility.
