I have a question about constructions like this: "Omar y Cristina son nuestros panaderos," e.g. "Omar and Cristina are our bakers." I understand it is "nuestros" because it is the nosotros form of the possessive adjective. However, I'm confused about the gender. Why is it masculine here?

how do you know when to add the "que"  or is it interchangeable?

I guessed this correctly but when I clicked on the explanation of past participle examples in Spanish it did not explain why it is escrita? 

Can someone please explain?

What is the key to make the answer "fue" rather than "estuvo"? It was a one time thing, done and over.

I need to have my eyes tested.  The correct answer is "Me necesitan hacer una revisión de ojos."  But for some reason that just sounds odd to me.  I could understand "Me revisáron los ojos" as meaning "I got my eyes checked" -- something that got done to me by some un-named third party.  But it just sounds weird to say "me necesitan" something.  I guess because the other examples deal with having something done to me, and this example relates to the third party have a state of mind or need.  Is this format with necesitar common?
