Explanation

Answer: A

PASSAGE

The deep ocean remains largely unexplored, with scientists estimating that over 80% of it has never been mapped or studied. New species are frequently discovered in these dark waters. _______ a 2022 expedition to the Mariana Trench identified three previously unknown species of fish.

Which choice completes the text with the most logical transition?

A. For instance,✓ Correct
B. In contrast,
C. Nevertheless,
D. Therefore,

Detailed Answer Explanation

This question asks you to choose the transition that best connects two ideas. General claim: New species are frequently discovered. Specific example: 2022 Mariana Trench expedition. 'For instance' introduces an illustrative example. Transitions signal the relationship between sentences or paragraphs. Determine the logical relationship (addition, contrast, cause-effect, example) and select the transition that accurately expresses it. The right transition makes the relationship between ideas crystal clear. Consider what logical connection exists: Is the second idea adding to the first? Contrasting it? Showing a result? The transition should accurately reflect this relationship.

Key Evidence:

• "New species are frequently discovered"

• "2022 expedition... identified three previously unknown species"

Why others are wrong: B (Contrast - the example supports, not contrasts with, the claim.), C (Contrast - there's no unexpected element here.), D (Cause/effect - the expedition isn't caused by species being discovered.).
