Set 1: Inferences (Intermediate)
Explanation
PASSAGE
A longitudinal study followed pairs of identical twins raised separately. Despite never meeting, many pairs showed remarkable similarities in occupation, hobbies, and even quirks like nail-biting. However, twins raised apart showed greater differences in personality traits like openness and agreeableness.
What can be inferred about the nature versus nurture debate from this study?
Detailed Explanation
This question asks you to draw a logical conclusion from the text. Similarities in occupation/hobbies (genetics?) but differences in personality traits (environment?) = both factors matter. A valid inference must be supported by evidence in the passage, even if not stated directly. Look for clues in the text that strongly suggest the answer. Avoid conclusions that require assumptions beyond what's written. Valid inferences are strongly supported by multiple pieces of evidence in the text. Be cautious of choices that go too far beyond what the passage actually states. The best inference is the one most directly supported by textual evidence.
Key Evidence:
• "remarkable similarities in occupation, hobbies"
• "greater differences in personality traits"
Why others are wrong: B (Personality differences suggest environment matters too.), C (Differences in separated twins show environmental impact.), D (They had 'remarkable similarities' in many areas.).
