Question

read the passage and then answer the question. scientists have found that bilinguals have many advantages over people who grow up hearing only one language at home. in a 2004 study, for example, bilingual participants performed better on 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? skillful slow challenged intelligent submit next up done for now? try these next:

Explanation:

To determine the meaning of "adept", we analyze the context. The passage says bilinguals performed better on mental puzzles and their brain differences enhance concentration for easier task completion. "Skillful" fits as it means proficient at something, matching the idea of bilinguals being good at problem - solving. "Slow" is the opposite of the described ability, "challenged" implies difficulty (contradicting the context), and "intelligent" is too broad; the passage focuses on proficiency in problem - solving, not general intelligence.

Answer:

skillful
