Set 5: Command of Evidence
Explanation
PASSAGE
Studies show that multitasking reduces productivity. When the brain switches between tasks, it takes time to refocus. What feels like doing two things at once is actually rapid task-switching, and each switch incurs a cognitive cost.
Why is multitasking less efficient than it seems?
Detailed Explanation
This question requires you to identify evidence that supports a claim. The text says switching 'takes time to refocus' and 'each switch incurs a cognitive cost.' This reduces efficiency. The best evidence directly and explicitly supports the stated claim without requiring assumptions. Match specific textual details or data points to the claim being made. The correct answer provides clear, direct support. Strong evidence directly addresses the claim without requiring additional interpretation. When evaluating options, look for quotes or data that explicitly support the statement. Weak evidence may be tangentially related but doesn't provide direct proof.
Key Evidence:
• "takes time to refocus"
• "cognitive cost"
Why others are wrong: A (The entire text argues the opposite.), B (This option is incorrect.), D (The premise says 'studies show,' not that they are unreliable.).
