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)

I won't answer the questions for you, but I'll translate what they mean (if you still need help after this, leave a comment (: )
1.) At what hour do they leave the house? (3:00)
2.) What do Inés and Cecilia see? (shoes)
3.) Where did Inés lose the money? (In the sports shop)
4.) Did you return to the store to look for it? (Yes)
(Not sure how well I did on 4, If I remember right "buscarlo" is an example of a reflexive verb.)
Answer:
"Las lluvias de anoche no pudieron <em><u>apagar</u></em> el incendio que <em><u>destruyó</u></em> mas de 50 millas de arboles. Cientos de animales trataron de <em><u>escaparse</u></em> corriendo entre los arboles. Pero sabemos que muchos <em><u>se murieron</u></em> en este gran incendio forestal."
Hope this helped!
The best answer to this sentence is C. Preferiria because it's only talking about one person, like "yo" means "I'. And the rest of the answer choices are talking about more than one person..
Translated - I "would rather" (means preferiria) travel by road and I would stay in a youth hostel.
So.. yea the answer is C. Preferiria. Glad to help!! :)
