Question 1 of 5.
Extract:First, the Moon’s gravity is less than 17 percent of Earth’s gravity, which is too low for sustained human existence. Secondly, the lack of an appreciable atmosphere on the Moon leads to temperature extremes. Depending on where the Sun is shining, temperatures can be too hot or too cold for humans. Lastly, the Moon lacks elements such as nitrogen and carbon that are necessary for breathable air and water.
Which of the following would be the best introductory sentence for the draft paragraph?
A. The establishment of human communities on the Moon has been seen as the next step in human exploration of space.
B. There are several reasons why colonization of the Moon would be difficult.
C. There are a number of ways to overcome the problems associated with colonization of the Moon.
D. Temperatures on the Moon would make it extremely difficult for human colonization.
Explanation: This sentence introduces the paragraph’s focus on multiple obstacles to lunar colonization (gravity, temperature, resources). Choice A is too optimistic; C suggests solutions, not problems; D focuses only on temperature.
Question 2 of 5.
Which of the following types of pathogens cause influenza in humans?
A. Bacterium
B. Virus
C. Fungus
D. Protozoan
Explanation: Influenza is caused by influenza viruses (family Orthomyxoviridae). Bacteria, fungi, and protozoa can cause other types of infections, but the flu is specifically a viral disease.
Question 3 of 5.
Which of the following articles will best help students understand the literary context of Langston Hughes’s poetry?
A. Technological Modernization and its Influence on Literary Forms
B. The Transcendentalists: Philosophical Beliefs Inspire a Literary Movement
C. How Economic Migration Contributed to an Artistic Revival
D. The Lost Generation: New Methods of Waging War Lead to New Approaches to Art
Explanation: Langston Hughes was a central figure of the Harlem Renaissance—a flourishing of Black art and literature in northern cities driven largely by the Great Migration of African Americans out of the rural South. An article on how economic migration spurred an artistic revival directly illuminates the social and cultural forces that shaped Hughes’s work.

A. recovery of classical learning and Christian theology
B. rejection of transferring pollen between the flowers of a plant
C. return to a medieval worldview of the primacy of the Church and the veneration of images in worship
D. revival of learning in Latin and Greek as well as the spread of writing in the vernacular
Explanation: The Renaissance—literally “rebirthâ€â€”marked a renewed interest in the literature, philosophy, and languages of ancient Greece and Rome. Scholars studied Latin and Greek texts and began writing serious works in their native tongues, breaking from the exclusively Church-centered medieval tradition.
Question 5 of 5.
A circular playground has an area of 314 square feet. Which of the following is the best estimate of the radius, in feet, of the playground?
A. 10 feet
B. 25 feet
C. 50 feet
D. 100 feet
Explanation: The area of a circle is given by A = πr². Given A = 314 ft², we approximate π ≈ 3.14, so r² ≈ 314 ÷ 3.14 ≈ 100, and r ≈ √100 = 10 feet. Choices B, C, and D yield areas far larger than 314 ft² when computed (e.g., r = 25 gives A ≈ 1962.5 ft²).
