I need help understanding how to ask/answer questions using the word 'Que'.

If the question is ?Que' estudias tu'? is the correct answer: 'Yo estudio ___' and then whatever you're studying or could I simply answer 'Estudio ____'

Also, in these questions, does one add the gerund form to verbs? As in, ?Que' mira el?' Would I answer: 'El mira television' or 'El mirando telvision?

Yes, it is! Either "Yo estudio" with the subject pronoun or just plain "Estudio" says the same thing.

Look closely at the question ¿Qué mira él? Often the verb is the same in the answer: él mira....... In any event, the verb in the question is the Present Indicative and your answer will be as well. You have no reason to use the Present Progressive, which is a form of estar with the gerund ('ndo form).

To ask a question using the word "que" in Spanish, you usually begin with "¿Qué?" which means "What?" or "Which?".

For example:
- ¿Qué estudias tú? means "What do you study?"
- ¿Qué mira él? means "What does he watch?"

To answer these questions, you can use different structures depending on the context. Let's break down your examples:

1. ¿Qué estudias tú? (What do you study?)
- The most common and concise way to answer this question is by saying "Yo estudio ___" followed by the subject you are studying.
- For example: "Yo estudio matemáticas" (I study mathematics).
- You can also simply say "Estudio ___" without using "Yo" (I), but it's more common and clear to include it.

2. ¿Qué mira él? (What does he watch?)
- To answer this question, you can say "Él mira ___" followed by the thing he is watching.
- For example: "Él mira televisión" (He watches television).
- In this case, you use the verb "mirar" (to watch) in its base form because it is not an ongoing action. The gerund form (ending with -ando or -iendo) is used for continuous actions rather than describing preferences or habits.

Remember to match the verb form with the subject and context of the sentence. Using "yo estudio" and "él mira" indicates who is performing the action. Additionally, refrain from using the gerund form when describing habits or preferences unless specifically required.
