If an author wanted to write a book that showed me the humor and the tragedy of life in a distant county he or she would likely write a

Tragicomedy?

(Why a distant contry? Is it relevant? If the focus is on the distance and difference of culture, then "tragicomedy" isn't probably the right answer. If the focus is in mixing humor and tragedy, then I suppose "tragicomedy" is right.)

"girls"

explanation:

a subject of a sentence is a noun or pronoun that shows who/what is performing the action (or verb) of the sentence.

in this case, the sentence states that the girls see. the girls are the ones who are performing the action, so they are the subject.

hope this !
