Lo. Lo (in this case) means “it”, in the masculine singular form.
So the answer is (a) because in English the word is “paid” and (b) and (c) just don’t make sense the sentence states that “I (paid) the ring at the jewelry store.” I hope this helps!
True. The spanish alphabet has the same vowels as the English alphabet.
in the first one I guess it doesn´t exists a correct answer, so you can mark whatever you want.
in the second one you have to put your name and age(sentence 1), write two things that you would like to do(sentence 2), next you have to write why would you like to do such activities(sentence 3) and in the fourth sentence you could you these example:
Hace mucho que no juego tenis.
Cierro
vuelvo
quitarse
me visto
pido
dormir
