ser vs estar multiple choice question and others

Question

Hello todo el mundo,

I have 2 questions. The first one is with creo que, which I believe is subjunctive. However, I think the answer should be C, but my teacher says A. C (sea) is subjunctive yo form of ser.

For the 2nd one, it is also subjunctive I think. The answer should be C, but I would like to confirm that answer. Thanks!!!

"no creo que" would be followed by the subjunctive - dennywells, Jan 9, 2014

"creo que" would be followed by the indicative. - dennywells, Jan 9, 2014

Answer 2

Yes, your teacher is correct. Es is a conjugation of ser, do you know when to use ser and estar? One hint: when in doubt, use estar. Estar is used for location and state of being. The other times, you will use ser. For your second question, you will use quiera. You are right, quiera is a subjunctive. Good work and keep it up! Hopefully I answered your questions!

I don't know how sound the advice for using estar over ser is. Personally, I see a lot more ser in writings of stories and such, and a lot more estar in conversations. - Helado_eclectico, Jan 10, 2014

But that's sort of like saying 'The British say yes more than no, so say yes to everything you are asked in England'. Still, you did explain their uses briefly, so props for that. - Helado_eclectico, Jan 10, 2014
