Explanation:

The question asks for a detail that directly supports bilingualism having advantages. The first option states bilingualism may lower Alzheimer's risk, which aligns with the text's finding that bilingual adults showed Alzheimer's signs later, a clear advantage. The other options either state research context, a general link, or define the disease, not a direct advantage of bilingualism.

Speaking more than one language may lessen risk of Alzheimer's disease.
