When quoting someone asking a question, do you put the question mark inside or outside the quotation marks?

When a plural word ending in s needs to be possessive, where does the apostrophe go?

In American English, the general rule is to place the question mark inside the quotation marks when the question is part of the quotation. For example:

She asked, "Do you want to go out for dinner?"

However, if the question mark is not part of the quotation itself, it should be placed outside the quotation marks. For example:

Did she say, "I will be there soon"?

Regarding the possessive form of plural words ending in "s," the general rule is to add an apostrophe after the "s" without an additional "s" after it. For example:

The girls' toys were scattered all over the room.

Here, the apostrophe is placed after the "s" because it is a plural possessive form indicating that the toys belong to the girls.
