Problem 2 - Entrance Test

Read the following paragraph and choose the best summary. Recent studies on neuroplasticity in adults challenge the long-held belief that the adult brain is fixed after adolescence. Research indicates that the brain can rewire itself through learning new skills, recovery from injuries, or adapting to environmental changes. For instance, individuals who learn to play a musical instrument show increased gray matter density in areas related to motor control and auditory processing. This adaptability suggests that cognitive decline in older adults may not be inevitable but rather a result of underutilized neural pathways.

Correct: C

The correct answer (Option C) correctly summarizes the paragraph by highlighting that adult brains can adapt through activities. Option A is contradicted by the premise. Option B is factually wrong, as the paragraph discusses learning, not surgery. Option D misrepresents the conclusion, which argues against inevitability.
