Complete the apprentice's diary entry about his chaotic first day at the magic tower by selecting the grammatically correct option.

The wizard furiously warned me ________ the glowing orb, asking how many times ________ to remind me.

The correct answer is not to touch / he had.

When reporting a negative command, we use "not to" + infinitive (warned me not to touch). For the reported question, we must use statement word order (subject + verb) rather than question word order, so "he had" is correct, whereas "had he" or "did he have" incorrectly retain the inverted structure of a direct question.
