Question 1

Read the passage. A community college extended its library hours during the final month of the semester. Evening visits increased, but the number of books checked out remained nearly unchanged. Student surveys indicated that most evening visitors used quiet study spaces and online databases. The library director concluded that checkout totals alone did not adequately measure the value of the extended hours. Which statement best expresses the main idea?

  1. A. Extended library hours caused students to read fewer books.
  2. B. Library use should be evaluated using more than book checkout totals.
  3. C. Online databases should replace the library's printed collection.
  4. D. Students prefer studying at night rather than during the day.

ANS: Answer: B

Correct: Library use should be evaluated using more than checkout totals because students benefited from study spaces and online resources without borrowing additional books. This captures the passage's central point. Incorrect: The passage does not measure how many books students read. It does not recommend replacing printed materials. Increased evening visits do not establish that students generally prefer nighttime study over daytime study.

Question 2

Read the passage. Researchers planted two groups of bean seedlings in identical soil and supplied equal amounts of water. One group received six hours of light daily, while the other received twelve hours. After three weeks, the second group had a greater average mass. The researchers noted that they had tested only one bean variety and that light requirements differ among plant species. Which conclusion is best supported by the passage?

  1. A. Every plant species grows best with twelve hours of daily light.
  2. B. The seedlings receiving six hours of light could not perform photosynthesis.
  3. C. Longer daily light exposure was associated with greater average mass in the tested bean variety.
  4. D. Water availability explained the difference in average mass between the groups.

ANS: Answer: C

Correct: The group receiving twelve hours of light had greater average mass, supporting an association between longer light exposure and greater mass under the conditions tested. Incorrect: Testing one bean variety does not justify a conclusion about every plant species. Six hours of light can support photosynthesis. Both groups received equal amounts of water, so the passage does not support water availability as the explanation.

Question 3

A laboratory instruction states, "Use a sterile container to collect the sample." What does sterile mean in this context?

  1. A. Free of all viable microorganisms
  2. B. Transparent enough to inspect the sample
  3. C. Designed to prevent evaporation
  4. D. Marked with measurement lines

ANS: Answer: A

Correct: Sterile means free of all viable microorganisms, including bacterial spores. Incorrect: Transparent describes a material that allows light to pass through it. Preventing evaporation describes a function of a sealed container, not sterility. Measurement lines make a container graduated, not sterile.

Question 4

An instructor writes, "The student's explanation was concise but included every essential step." Which word is closest in meaning to concise?

  1. A. Uncertain
  2. B. Repetitive
  3. C. Complicated
  4. D. Brief

Question 5

Which sentence uses correct subject–verb agreement?

  1. A. The list of required supplies are on the desk.
  2. B. Each of the laboratory tables have a microscope.
  3. C. The results of the experiment support the hypothesis.
  4. D. The instructor, along with two students, explain the procedure.
