Which is right? Complete the sentenses.

2. What do you think? ... (Does she come / Will she come / Is she coming) home laty today.

3. When ... (does she come / has she come / did she come)home yesterday
..... (At / in) four o'clock

4. .... (Does she come / Has she come / Did she come) home yet.
I ... (don't know / didn't know / haven't know)

≡И так далее, объясните мне пожалуйста принцип подбора верных ответов.≡

Огромное спасибо

1)When does she come to home?-действие совершается обычно,значит Present Simple.2)Will she come home late today?-действие будет в будущем,значит Future Simple.3)When did she come home yesterday?At four o'clock.-Действие уже совершилось и закончилось,значит Past Simple.At four o'clock-с конкретным временем пишется предлог AT.4)Hasn't she came home yet.I don't know-Есть наречие времени yet,следовательно пишется Present Perfect в негативной форме.
