5 The following text is from a 1955 translation of Samuel Beckett’s 1951 novel Molloy (translated by the author and Patrick Bowles). In the text, Molloy has arrived at the town ramparts, an elevated walkway atop the city walls. And having cleared the ramparts I had to confess the sky was clearing, prior to its winding in the other shroud, night. Yes, the great cloud was ravelling, discovering here and there a pale and dying sky, and the sun, already down, was manifest in the livid tongues of fire darting towards the zenith, falling and darting again, ever more pale and languid, and doomed no sooner lit to be extinguished. ©1955 by Grove Press, Inc. As used in the text, what does the word “manifest” most nearly mean?

6 In the past, historians who wanted to examine Frederick Douglass’s diary and other personal papers had to visit the Library of Congress in Washington, DC, to view them on microfilm (film containing scaled-down reproductions of documents). But traveling to the library often added time and costs to research projects. Now, by going to the library’s website, researchers can access digitized versions of Douglass’s papers without physically going anywhere. Which choice best describes the function of the underlined portion in the text as a whole?
7 Following the eradication of the gray wolf in Yellowstone National Park in 1926, the population of elk—a primary prey of the gray wolf—exceeded a healthy size for the park’s ecosystem. Elk overpopulation led to overgrazing of areas that a multitude of other animals relied on for food and shelter. As scientists began to see how essential the gray wolf was to the Yellowstone food chain, ecological restoration strategies were employed to reintroduce the gray wolf to the park in 1996. The rebound effect in the park’s natural ecosystem was noticed almost immediately. Which choice best describes the overall structure of the text?
8 A team of researchers discovered that Matabele ants can identify an infected wound in a member of the colony and then treat the infection by covering the wound with antimicrobial secretions that the ants produce. The team found that the mortality rate for Matabele ants with infected injuries was reduced by 90% with this treatment, and they are hopeful that this discovery could aid in the development of new antibiotics for human use.

9 Built in the 1970s, Raccoon Mountain is a pumped- storage hydropower facility (a “water-battery”) located in the United States along the Tennessee River. When energy demand is low, excess power from the regional electric utility’s nuclear plants is used to pump water (from a lower reservoir filled from the Tennessee River) up a shaft to the summit lake, where the water is stored as gravitational potential energy. When energy demand peaks, the water drains down from the summit lake, spinning turbines and generating upward of 1,700 megawatts of power—enough to power one million homes for twenty hours. Which choice best states the main purpose of the text?

10 A cable provider wanted to know how many of its 30,000 customers would be interested in a new service plan. The provider selected 300 customers at random and asked each customer whether the customer would be interested in the new plan. Of those surveyed, 8 said they would be interested. Which of the following is the best estimate of the total number of customers who would be interested in the new service plan?
