Question

certain mental puzzles than their monolingual counterparts. it is believed that people who are bilingual are so adept at problem solving because their brains have developed differently. these differences, revealed through brain scans and experiments, enhance their concentration, allowing them to complete some tasks with greater ease.
bilingualism seems to influence the brain across the span of a person’s life. differences first present themselves during infancy. studies have found that babies exposed to two languages from birth can acclimate to new situations quickly, responding to changes in their environment faster than those raised with only one language. other studies have found that bilingualism provides advantages in old age as well. bilingual adults tend to experience memory loss at a later age compared to monolingual adults.
what is the meaning of adept as used in the passage?
intelligent
slow
skillful

Explanation:

To determine the meaning of "adept", we analyze the context. The passage says bilingual people can solve problems with greater ease due to brain differences that enhance concentration. "Intelligent" is too general, "slow" contradicts the context (they complete tasks easier), and "skillful" fits as being good at problem - solving implies proficiency/skill in it.

Answer:

skillful
