Set 14: Transitions (Intermediate)
Explanation
PASSAGE
Black holes were once thought to be cosmic dead ends from which nothing could escape. Recent research, however, suggests that information may not be permanently lost. _______ Stephen Hawking proposed that black holes emit radiation and eventually evaporate over vast timescales.
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. Hawking's radiation theory supports and extends the idea that black holes aren't permanent. 'In fact' emphasizes this confirming evidence. 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:
• "information may not be permanently lost"
• "emit radiation and eventually evaporate"
Why others are wrong: B (Contrast - Hawking's theory supports the new understanding.), A (Cause/effect - Hawking's proposal preceded, not resulted from, recent research.), D (Contrast - this is supporting evidence, not an unexpected development.).
