Reading Comprehension Main Idea Mock Tests

Read the following passage: "The study of ancient DNA has revolutionized our understanding of human evolution and migration patterns. By extracting and sequencing DNA from ancient skeletal remains, researchers have been able to identify previously unknown hominin species, trace the interbreeding between modern humans and Neanderthals, and map the migration routes that ancient populations took across the globe. The field has also revealed that many modern human populations carry small amounts of Neanderthal DNA, which can influence traits such as immune function and skin pigmentation. However, the extraction of ancient DNA is technically challenging, and samples can be contaminated by modern DNA, requiring specialized facilities and rigorous protocols."

Read the following passage: "Genetic engineering has made remarkable progress in recent decades, from the sequencing of the human genome to the development of CRISPR gene-editing technology. These advances have promised cures for genetic diseases, improved crop yields, and new approaches to treating cancer. However, the ability to modify human genes raises profound ethical questions. The possibility of creating germline edits — changes that would be passed on to future generations — has prompted calls for a global moratorium on clinical applications. The scientific community must engage with policymakers, ethicists, and the public to establish appropriate safeguards while not unnecessarily hindering beneficial research."

Read the following passage: "The rapid growth of e-commerce has fundamentally transformed the retail landscape, leading to the closure of thousands of physical stores and the decline of many well-known retail chains. While online shopping offers convenience and often lower prices, it has also had significant effects on urban centers, which have lost foot traffic that supported restaurants, theaters, and other businesses. Some city planners are now rethinking urban design to account for this shift, proposing mixed-use developments that combine residential, commercial, and recreational spaces to create destinations that people have reason to visit in person, regardless of the availability of online alternatives."

Read the following passage: "Economic historians have long debated the causes of the Industrial Revolution, which began in Britain during the mid-eighteenth century. Traditional theories emphasized Britain's abundant coal reserves and growing colonial markets. However, recent scholarship points to institutional factors: the strengthening of property rights, the development of reliable legal frameworks for contracts, and the emergence of financial institutions capable of mobilizing capital for large-scale enterprise. These institutional innovations, rather than natural resource endowments alone, appear to have created the conditions necessary for sustained industrial growth." The primary purpose of the passage is to:

Read the following passage: "Many people believe that multitasking — performing multiple cognitive tasks simultaneously — improves productivity. However, research in cognitive psychology consistently demonstrates that the human brain is not designed to handle multiple attention-demanding tasks at once. Instead, what people experience as multitasking is actually rapid task-switching, which comes with significant cognitive costs. Studies have found that task-switching can reduce productivity by up to 40 percent and increase error rates. The constant shifting of attention also prevents deep engagement with any single task, reducing the quality of work." Which of the following would be the most effective title for this passage?

Read the following passage and answer the question: The concept of financial inclusion in India has evolved from mere account opening to ensuring meaningful access to a range of financial products. While the Pradhan Mantri Jan Dhan Yojana has opened over 500 million bank accounts, experts argue that account activation and regular usage remain low in rural areas. The introduction of Aadhaar-linked seedling has helped reduce duplicate and fake accounts, but digital literacy remains a significant barrier. Financial inclusion, therefore, requires not just infrastructure but also behavioural change among underserved populations. What does the passage conclude about financial inclusion?

Read the following passage: "The concept of artificial general intelligence, or AGI, refers to a hypothetical form of AI that possesses the ability to understand, learn, and apply knowledge across a wide range of tasks at a level comparable to human cognitive ability. Unlike narrow AI systems, which excel at specific tasks such as playing chess or recognizing images, AGI would be capable of transferring knowledge from one domain to another in a flexible and adaptive manner. While some experts predict that AGI could be achieved within the next few decades, others argue that the challenges of replicating human-level general intelligence are far more complex than current AI research acknowledges."

Read the following passage: "Marine biologists have discovered that coral reefs are home to an extraordinary diversity of species, with some estimates suggesting that nearly one-quarter of all marine species depend on reefs for survival. Despite occupying less than one percent of the ocean floor, coral ecosystems support approximately 25 percent of marine life. This remarkable biodiversity makes coral reefs one of the most valuable ecosystems on Earth. However, coral reefs are under threat from climate change, ocean acidification, pollution, and overfishing. Scientists warn that without significant conservation efforts, many coral reef systems could face irreversible damage within the next few decades."
