So i'm writing a poem for class, and can someone please tell me if "And you shall excite" is an actual sentence?

yes. use it if you intend for it to mean "you will make people excited"

It can be a sentence, but if that's all, then it would be incomplete. Unless you say something like

"The ability to 'excite' interest in others)

Excite means to bring out or cause strong feelings of enthusiasm and eagerness (excitedness)

i   believe   the   answer   is   d

when making an inference, the reader should be sure to support the inference with

evidence

a is an educated guess about what will happen.

c. prediction

when new information proves that a reader's prediction is wrong, the reader should

make a new prediction based on the new information.
