Which term on the list is a test that helps identify problems with language?

• A. Diagnostic test
• B. Text as a Vehicle for Information
• C. Discourse management
• D. Diglossia

Answer: (A)

A diagnostic test is the best fit because it refers to an assessment tool specifically designed to uncover language problems and pinpoint where intervention is needed. It drills into particular language domains—receptive and expressive language, vocabulary, grammar, syntax, phonology, and pragmatics—and provides detailed results that guide targeted instruction or therapy. The other terms describe concepts rather than an assessment: using text to convey information, how discourse is organized in conversation, and the existence of two language varieties in a community. So the term that identifies language problems through testing is the diagnostic test.
