Explanation

Answer: B

PASSAGE

A student is writing about sleep deprivation. The student wants to highlight its effects on cognitive function. Notes: - Adults need 7-9 hours of sleep per night. - Sleep deprivation impairs memory consolidation. - Lack of sleep reduces reaction time and decision-making ability. - Chronic sleep loss is linked to weight gain.

Which choice most effectively uses information from the notes to accomplish the student's goal?

A. Chronic sleep loss has been linked to weight gain and other health problems.
B. By impairing memory consolidation and reducing reaction time and decision-making ability, sleep deprivation significantly diminishes cognitive function.✓ Correct
C. Most adults need between 7 and 9 hours of sleep each night for optimal health.
D. Getting enough sleep is important for maintaining overall health and wellness.

Detailed Answer Explanation

This question asks you to effectively combine information to achieve a goal. The goal is cognitive function effects. Memory impairment, reaction time, and decision-making are cognitive functions. The correct synthesis will use relevant details from the notes in a logical, purposeful way. Focus on what the question asks you to accomplish, then choose the answer that best achieves that goal using the provided information. Effective synthesis requires selecting and combining the most relevant information to achieve a specific purpose. Not all provided notes may be equally useful. Focus on what best accomplishes the stated goal while maintaining logical coherence.

Key Evidence:

• "highlight its effects on cognitive function"

• "impairs memory consolidation"

• "reduces reaction time and decision-making"

Why others are wrong: A (Addresses physical effects (weight gain), not cognitive.), C (States sleep needs, not deprivation effects.), D (General statement; doesn't address specific cognitive effects.).
