Help the baffled detective write his official report regarding the prime suspect by choosing the correct phrase to complete the sentence.

The detective interrogated the squirrel, demanding to know ________ the acorns and why ________ at him with such disdain.

The correct answer is where it had hidden / it was looking.

In indirect (reported) questions, the word order changes from question format (verb-subject) to statement format (subject-verb), and auxiliary verbs like "did" are dropped. Additionally, the tenses backshift: the direct past simple ("where did you hide") becomes past perfect ("where it had hidden"), and present continuous ("why are you looking") becomes past continuous ("why it was looking").
