Sometimes it's not hard. "What color is the tongue of a giraffe?" can be answered in less than eight words trivially. Most models will give you paragraphs, bullet points, and followup questions.
I'm often okay if the answer is longer but not hiding the real answer; a couple of paragraphs that I can skim the answer from instantly is okay. When it really buries it I have to follow up to express the format and type of answer I want.
