Hi
The answer to the first question is C. Tu n’aimes pas les shorts verts.
It means "You don't like the green shorts.".
The reason it is C is that in French when a noun that an adjective describes is plural, the adjective is plural as well. Verts is the correct plural form of green in French.
The answer to the second question is A. Vous aimez le pull étroit.
It means "You like the narrow sweater.".
The reason it is A is that the noun (pull) is masculine, and it isn't plural. So I picked the masculine adjective that isn't plural.
Hope this helps! :)
