El oración de primo. "Mar Chiquita es una playa famosa" es cierta, porque Mar Chiquita es pequeño (y famosa).
The first sentence is true, because Mar Chiquita [Beach] is small (and famous).
Also usually the longest answer choice is correct ;)
Cognates are really simple. they are words that are almost the same in both languages. An example of a true one is: poem- el poema
A false cognate is asistir looks like asist but really it means to attend
The answer would be A.
Una computadora= The computer
The other answers would not have anything to do with una computadora since the other options are other subjects such as history, spanish, and science.
Hope this helps! :3
