Question

select the text from the paragraph that best helps you understand that adept means skillful. there may be more than one correct choice. 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.

Explanation:

To understand that "adept" means "skillful", we look for context showing proficiency. The sentence "bilingual participants performed better on certain mental puzzles than their monolingual counterparts" and "allowing them to complete some tasks with greater ease" (along with "adept at problem solving") helps. The key text is "bilingual participants performed better on certain mental puzzles than their monolingual counterparts" (and also "allowing them to complete some tasks with greater ease" in relation to adept at problem - solving).

Answer:

• "bilingual participants performed better on certain mental puzzles than their monolingual counterparts"
• "allowing them to complete some tasks with greater ease"
