Set 5: Transitions (Intermediate)
Explanation
PASSAGE
Microplastics have been found in every ocean, in Arctic ice, and even in human blood. These tiny plastic particles break down from larger debris but never fully decompose. _______ they accumulate in the food chain, with unknown long-term health consequences.
Which choice completes the text with the most logical transition?
Detailed Answer Explanation
This question asks you to choose the transition that best connects two ideas. Because plastics don't decompose, they accumulate. 'As such' shows how the non-decomposition leads to the accumulation problem. 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:
• "never fully decompose"
• "accumulate in the food chain"
Why others are wrong: A (Restatement - accumulation is a consequence, not a restatement of non-decomposition.), B (Alternative - accumulation results from, not replaces, non-decomposition.), D (Contrast - accumulation is a logical result, not an unexpected outcome.).
