In february, what is the temperature in Chile?
The answer is (hola el senor gonzales)
The correct way to write the sentence is;
Ustedes tienen que hablar cuando yo les pregunte algo.
o
Usted tiene que hablar y responder la pregunta que les ago.
The correct answer is aquella, because we would use the word if there was a difference in the distance. Like if you were in the right corner of a room, and the guitar was at the left corner of the room. And another reason is because aquella is feminine and in spanish, guitar is feminine.
