What do you do when you truly have more than one question?

Use a summary ‘answer' rather than a synthesis only when you absolutely have to

Occasionally there are two questions, or even more. When that is truly the case – and you can't synthesise them into one single overarching question – go with it. Answer them and provide a summary answer rather than a synthesis to help the reader have true context.

A summarised answer might say something like this: “There were three issues we needed to resolve before we could proceed with Project x”

A synthesised answer might say something like this: “There are too many risks associated with Project X to proceed this month”.
