Answer:
4. A
5. C
6. B
Explanation:
4. Hacer una pregunnta means to ask a question. It would be the best answer because entregar un informe means to give in a document which has nothing to do with it. Llegar tarde would just make it worse because you wouldn't want to be late. Contestar means answer but how can you answer something when you don't even understand so yeah A would be your best choice.
5. C would be your best answer because pensar is past tense. Pienso would be used if it was you who's thinking. Pense would be past tense too.
I assume you mean the verb conjugation of the present perfect? It's used to talk about things that started in the past, but are still going on right now (in the present) or something that happened recently.
To form it use the past participle of haber + the past participle of another word. For example:
He visto las montañas de Perú
(I have seen the mountains of Peru)
Hemos vuelto para comprar la leche
(We have returned to buy milk)
Habéis cantado muy bien
(You have/You've sung very well)
