Explicit-location queries can include a bracketed city and a language tag.

• A. They always include a city and a language tag.
• B. They can include a bracketed city and a language tag.
• C. They never include language tags.
• D. They include only country codes.

Answer: (B)

Explicit-location queries are designed to carry location information directly in the text. A bracketed city shows exactly where the results should be focused, and a language tag tells the system which language to use for the results. Because these elements are optional tools for refining the query, it’s correct to say they can include a bracketed city and a language tag. You might see something like [Toronto] en-CA to fetch results rooted in Toronto in Canadian English, or you might see only one of those elements depending on what the query caller wants. The other statements are too rigid: some queries won’t include a city, or won’t include a language tag, and some responses rely on country codes instead of a full city name.
