Trusted Tester 11B Language of Parts requires which of the following about content in a different language from the default?

• A. The language for content segments that differ from the default can be programmatically determined.
• B. The language for content segments that differ from the default cannot be determined.
• C. The language for content segments must always match the page language.
• D. Language of parts is optional for accessibility.

Answer: (A)

When content is in a different language from the page’s default, it needs a machine-readable way to indicate that language so assistive technologies can handle it correctly. This is about making the language of those parts determinable programmatically, typically by tagging the segment with its language (for example, using a lang attribute in HTML). That way, a screen reader or other tool can switch to the appropriate pronunciation, rules, and reading behavior for that portion.

This is why the best choice says the language for content segments that differ from the default can be programmatically determined. The other options clash with how multilingual content should be handled: the language isn’t something that can’t be determined, because marking it makes it detectable; it doesn’t have to always match the page language, since parts can legitimately be in another language; and it’s not optional for accessibility—providing a clear language marker for non-default language parts is essential for accessible reading.
