Question

select the text from the paragraph that best helps you understand that bilinguals means people who can speak two languages. 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 "bilinguals" means people who can speak two languages, we look for text that contrasts them with those who know only one language. The phrase "people who grow up hearing only one language at home" provides this contrast, as bilinguals would be those who don't just hear one language (implying they hear two, hence can speak two). Also, "monolingual counterparts" helps as "monolingual" means knowing one language, so "bilingual" participants (who outperformed monolinguals) must know two.

Answer:

• "people who grow up hearing only one language at home"
• "monolingual counterparts"
