How do I know when there is an indirect question?

Indirect questions have a 3 identifiable features to look out for! 1) They will be introduced by a question verb or a knowledge verb such as rogare (to ask) or scire (to know). 2) This will be followed by a question word such as quid (what), cur (why), and quo modo (in what way). 3) Finally, indirect questions in latin use the subjunctive. This means that the verb within the question will use the subjunctive forms. E.g. rogavit quid facerent. He asked what they were doing. Here we have the question verb (rogavit), the question word (quid), and our subjunctive verb (facerent).
