The interrogation point needs careful consideration, for there is a general tendency in certain kinds of questions to substitute the period. For instance, a request is often put in the form of a question to make it seem unlike a demand, but the sentence requires the interrogation point, not the period. For example:

May I be excused during the second period to make up some work in history with Mr. Eddy ?

Will you kindly notify the committee at once if you cannot be present, since definite arrangements should be made with the caterer ?

IV. An interrogation point should follow every direct question, but is not required after an indirect question.

Did you recognize me?

You could not see?

"Did you see that robin?" asked Mary.

He asked who was ready to go.

Will you please hand me that book?
