Minor grammar point, plural vs. possessive. You made a mistake in this regard both in the thread title (twice) and in your post.
Questions, Operators = plural. Question's, Operator's = possessive. "boots and uniforms" (plural) "boots and uniform's" (possessive). What you were going for in all instances was the plural, what you used is the possessive. It's a little thing, but sometimes the little things matter.
