1. Which of these pairs represents an example of convergent evolution?

• A. Humans and chimpanzees
• B. Bats and birds
• C. Dolphins and sharks
• D. Snakes and earthworms

Correct answer: B

Rationale: Convergent evolution refers to the process by which different species independently evolve similar traits or characteristics due to similar environmental pressures. In the case of bats and birds, both have evolved wings for flight despite not sharing a recent common ancestor with wings. Bats are mammals, while birds are avians, yet they both have wings adapted for flight, which is a classic example of convergent evolution. A) Humans and chimpanzees share a common ancestor and have not independently evolved similar traits. C) Dolphins and sharks are not closely related, and their similarities are due to adaptations to their aquatic environment rather than convergent evolution. D) Snakes and earthworms belong to different classes (reptiles and annelids, respectively) and do not share recent common ancestors, making their similarities not a result of convergent evolution.

2. Which definition best fits the word zymosis?

• A. Discontent
• B. An infectious disease
• C. Poverty
• D. Bad luck

Correct answer: B

Rationale: In this passage, the word 'zymosis' is described as a malady that the narrator has been suffering from since boyhood. This aligns with the definition of zymosis as an infectious disease, making option B the correct choice. Choices A, C, and D are incorrect because the passage clearly indicates that zymosis is a medical condition, not related to feelings of discontent, poverty, or bad luck.

3. How does Wilde portray the institution of marriage in The Importance of Being Earnest?

• A. As a romantic union between two individuals.
• B. As a social contract designed for economic and social gain.
• C. As a trivial and superficial agreement.
• D. As a necessary evil in a structured society.

Correct answer: B

Rationale: In The Importance of Being Earnest, Wilde portrays marriage as a social contract rather than a romantic union. The play satirizes the transactional nature of marriage in the society Wilde critiques. Characters like Lady Bracknell's interrogation of Jack highlight how marriage is viewed as a means for economic and social gain rather than genuine affection, emphasizing the societal norms of the time. Choice A is incorrect because Wilde's portrayal goes beyond a simple romantic view of marriage. Choice C is incorrect as it oversimplifies Wilde's critique of marriage and societal norms. Choice D is incorrect as it doesn't capture the nuanced satire Wilde employs in dissecting the institution of marriage.

4. What is the meaning of the prefix 'pre-'?

• A. After
• B. Before
• C. During
• D. Against

Correct answer: B

Rationale: The correct answer is B: 'Before.' The prefix 'pre-' means 'before,' indicating something that comes before the main action or event. For example, in words like 'preview' or 'predict,' the prefix 'pre-' implies anticipation or happening before the complete action. Choices A, C, and D are incorrect. 'After' (Choice A) is the opposite of 'before,' 'During' (Choice C) implies something happening at the same time, not before, and 'Against' (Choice D) indicates opposition, which is unrelated to the prefix 'pre-.' Therefore, the answer is 'Before.'

5. What is the primary purpose of conducting an experiment?

• A. to test a hypothesis
• B. to collect data
• C. to identify a control state
• D. to choose variables

Correct answer: A

Rationale: The correct answer is A: 'to test a hypothesis.' The primary purpose of conducting an experiment is to test a hypothesis. This process allows researchers to gather empirical evidence to either support or refute a proposed hypothesis. By systematically manipulating variables and observing outcomes, scientists can draw conclusions about the relationships between these variables. Choice B, 'to collect data,' is a common step within an experiment, but the ultimate goal is to test a specific hypothesis. Choice C, 'to identify a control state,' is not the primary purpose but rather a methodological consideration within an experiment to ensure reliable results. Choice D, 'to choose variables,' is a step that is typically done before conducting the experiment and is not the primary purpose of the experiment itself.
