After months of watching De Lacey's family, the creature decided to introduce himself. The creature was surprised about what happened. Unlike the other people he had introduced himself to, De Lacey's family was kind and accepting, or so he thought.

The boldface verbs in the sentence use indicative mood. Since the interrogative mood of a sentence always asks a question, we can change the statement “Tom will have a moment of great inspiration” into a question. To do this, we can flip the helping verb, which in this case is will, to the front of the sentence so that it now reads “Will Tom have a moment of great inspiration?” This sentence now asks a question, therefore it now uses interrogative mood.
A commemorative speech has to do with celebrating something or someone. If you want to pay tribute to someone (and there isn't a specific topic you have to talk about), you should talk about someone important to you, someone whom you love and who inspires you - it could be a family member or a friend, or someone you look up to.
