Key phrases being "broad sets of documents" from the comment you're responding to and "reports or answers in writing to specific questions" in the FTC's blurb.
"Specific" doesn't mean "narrow." "What were the ingredients from every meal you've had in your life?" or "What is the current address of every person with the first name 'John'?" is a specific question.
All it means (in English) is that it's clear which information should be included in the reply, not a limitation on the range of information that can be asked for.
