Text Structure & Purpose Mock Tests

Read the following passage: The word cantaloupe entered the English language in the early 18th century, borrowed from the French canteloupe, which itself may derive from the Latin melopeo — meaning honey melon. The fruit, native to North Africa, was cultivated by the ancient Egyptians and is now grown on every inhabited continent. In the United States, commercial production centers primarily in the Midwest and California. What is the primary purpose of the passage?

In this excerpt from a science article: "CRISPR-Cas9 is a gene-editing technology that allows scientists to modify DNA with unprecedented precision. Since its adaptation for use in human cells in 2012, it has accelerated research in agriculture, medicine, and basic biology — sparking both excitement about potential treatments and ethical debates about the limits of genetic modification." What is the primary purpose of this passage?

In this excerpt from a psychology research summary: "A 2025 study published in the Journal of Experimental Psychology found that participants who spent ten minutes writing about a positive personal experience before taking a stress test showed significantly lower cortisol levels than those who wrote about a neutral topic. However, the effect was not observed in participants who had a history of clinical depression." Which choice best describes the relationship between the two sentences? a) The second sentence provides an exception to the finding described in the first. b) The second sentence offers a alternative explanation for the results in the first. c) The second sentence contradicts the methodology of the study described in the first. d) The second sentence restates the main finding of the first in different words.

In this passage from a philosophy essay: "Deontology, most famously associated with Immanuel Kant, holds that actions are morally right if they follow universal rules or duties, regardless of consequences. Utilitarianism, by contrast, judges actions by their outcomes. This fundamental disagreement between duty-based and outcome-based ethics continues to shape moral philosophy today." What is the primary purpose of this passage?

The following passage is from a 2023 article about urban planning: Many cities have adopted what planners call "15-minute neighborhoods," where residents can access essential services within a 15-minute walk or bike ride. Critics argue this model reduces efficiency by spreading resources thinly across many small districts rather than concentrating them in centralized hubs. Proponents counter that centralized hubs create traffic congestion and disproportionately burden residents without cars. What can most reasonably be inferred about the debate over 15-minute neighborhoods?

The following appears in an opinion editorial: "The city's decision to replace the public library with a commercial shopping center is short-sighted. A library is not merely a building with books; it is a community space that provides free access to information, educational programs, and a safe environment for people of all ages. Removing it serves immediate economic interests but deprives residents of a vital public resource." Which choice best describes the structure of the argument?

In this excerpt from a scientific article: "The antibiotic resistance of Staphylococcus aureus has intensified due to the overprescription of methicillin. Bacteria that possess random genetic mutations conferring resistance survive treatment and reproduce, passing the resistant genes to their offspring — a classic example of natural selection in action." What role does the second sentence play in the passage?

In this excerpt from a speech about climate policy: "Some policymakers argue that carbon taxes will stifle economic growth, yet history shows that well-designed environmental regulations can stimulate innovation and create new industries. The renewable energy sector, for instance, now employs millions of workers worldwide — a reality that seemed distant when such policies were first proposed." What is the speaker's primary purpose in this passage?
