Can someone tell me how to put a source in a paper?

this is how I think my teacher told me to do it:

“Tom was a dead man the minute Mayella Ewell opened her mouth and screamed” (Lee 241).

how do you do it if the quote is a question

What you have is correct.

If it's a question, it should be like this at the end: ... ?" (Lee 241)

=)

Then there should be no period after (Lee 241)

When the quotation is not a question, the citation should be just as you entered it in the first post. Only if there's to be a question mark somewhere (inside or outside the quotation marks) would you vary it. See the first example given here:

um..those don't really say what i'm looking for about the question

does it go: "Did you see that?" (author 73).

or: "Did you see that?" (author 73)

or: "Did you see that" (author 73)?

Either the first or second; definitely not the third, since the citation is not part of the question.

The first one bothers me because of using two end-punctuation marks in the same sentence.

The second seems to be the best of the three.

thank you

IT GOES "DID YOU SEE THAT?" BUT IT HAVES TO HAVE A SPEAKER LIKE "DID YOU SEE THAT?"ASKED APRIL. GET IT?

Yes, you are correct. When quoting a question, you would use quotation marks and include the question mark inside the quotation marks. Here's an example:

"Did you see that?" asked April (Author 73).

The question mark is placed inside the quotation marks because it is part of the quote itself.
