1. In an experiment where five tropical plants are kept at varying humidity levels in a greenhouse for three months, while one plant is left outside in normal conditions, with plant height measured weekly, what serves as the control of the experiment?

• A. Plant height for each tropical plant
• B. The plant left outside in normal conditions
• C. Humidity level readings in the greenhouse
• D. Amount of time used to study plant height

Correct answer: B

Rationale: The correct answer is B. The plant left outside in normal conditions acts as the control in the experiment. It provides a standard reference point for comparison to assess the impact of the varying humidity levels on the growth of the tropical plants. Choice A is incorrect because it refers to the dependent variable being measured, not the control. Choice C is incorrect as humidity levels in the greenhouse are part of the experimental conditions, not the control. Choice D is incorrect as the time used for studying plant height is a parameter of the experiment and not the control.

2. What defines a proper fraction versus an improper fraction?

• A. Proper: numerator < denominator; Improper: numerator > denominator
• B. Proper: numerator > denominator; Improper: numerator < denominator
• C. Proper: numerator = denominator; Improper: numerator < denominator
• D. Proper: numerator < denominator; Improper: numerator = denominator

Correct answer: A

Rationale: A proper fraction is characterized by having a numerator smaller than the denominator, while an improper fraction has a numerator larger than the denominator. Therefore, choice A is correct. Choice B is incorrect because it states the opposite relationship between the numerator and denominator for proper and improper fractions. Choice C is incorrect as it describes a fraction where the numerator is equal to the denominator, which is a different concept. Choice D is incorrect as it associates a numerator being smaller than the denominator with an improper fraction, which is inaccurate.

3. What is the author's point of view?

• A. First person
• B. Third person limited
• C. Third person omniscient
• D. Objective

Correct answer: B

Rationale: The passage is told from a third person limited point of view because the thoughts and perspectives of two specific characters, Michael and Lana June, are presented. The narrator provides insight into their thoughts, but remains limited to their viewpoints without revealing the thoughts of any other characters. This extract demonstrates the limited perspective by showing the inner thoughts of Michael and Lana June, indicating a third person limited narrative. Third person omniscient would involve knowing the thoughts of all characters, which is not the case here. First person would involve using 'I' to narrate, which is absent. Objective point of view would present only observable actions without any character's thoughts or feelings, which is not the case in this passage.

4. Which of the following best describes the purpose of the passage?

• A. to inform Mr. Morgan that he will likely not receive an offer for the job of Lead Technician due to the high number of applicants
• B. to express gratitude to Mr. Morgan for applying for the position of Lead Technician
• C. to offer Mr. Morgan the position of Lead Technician
• D. to notify Mr. Morgan that the review of candidates will take longer than expected

Correct answer: A

Rationale: The purpose of the passage is to inform Mr. Morgan that he will likely not receive an offer for the job of Lead Technician due to the high number of applicants. The passage mentions the high volume of applications and the competitive nature of the selection process, indicating that Mr. Morgan may not be successful. Choice B is incorrect because the passage does not express gratitude to Mr. Morgan but rather informs him of the situation. Choice C is incorrect as there is no offer made in the passage. Choice D is incorrect as the passage does not specifically state that the review will take longer than expected, but rather that it will take longer than previously stated.

5. The top-secret blueprints were for an intergalactic spaceship. Which of the following is the meaning of the prefix 'inter-' as used in the sentence above?

• A. Among
• B. Below
• C. Around
• D. Above

Correct answer: A

Rationale: The prefix 'inter-' means 'among' or 'between,' which is most fitting in the context of 'intergalactic' as 'among galaxies.' 'Below,' 'around,' and 'above' do not convey the correct meaning of the prefix 'inter-' in this context.
