Set 2: Cross-Text Connections

Explanation

Answer: A

PASSAGE

Text 1 Neuroplasticity is the brain's ability to reorganize itself by forming new neural connections. It allows neurons to compensate for injury and adjust their activities in response to new situations or changes in the environment. Text 2 While beneficial for learning and recovery, plasticity has a 'dark side'. Maladaptive plasticity can lead to phantom limb pain or ingrained bad habits. The same mechanism that allows us to learn the violin can also wire the brain for chronic pain or addiction.

What duality of neuroplasticity do the texts collectively present?

A. It is a neutral mechanism that can facilitate both adaptation (recovery) and dysfunction (pain/addiction).✓ Correct
B. It is always good.
C. It is always bad.
D. It only happens in children.

Detailed Explanation

Text 1: Beneficial (Recovery/Learning). Text 2: Dark side (Pain/Addiction). Duality: Neutral mechanism, pos/neg outcomes.

Key Evidence:

• "beneficial"

• "plasticity has a 'dark side'"

• "same mechanism"

Why others are wrong: B (Text 2.), C (Text 1.), D (Not mentioned.).
