Can someone please check these 4 sentences?

Question

a. La bibliothèque à New York est plus grande que la bibliothèque à Paris.

b. Les résidences des New York sont plus moderns que les résidences de Paris.

c. Le campus de New York est moins intéressant que le campus de Paris.

d. Les étudiants des New York sont aussi intelligent que les étudiants de Paris.

Answer 1

I'll send this to one of our French experts, SraJMcGin.

Answer 2

a. ok
b. rather than "des" = de New York...modernes (la résidence = feminine)
c. ok
d. again, rather than "des" = de New York...intelligents (plural subject "les étudiants" requires plural adjective = intelligents)

I"ll flag this and come back later to see if you have other questions.

Sra (aka Mme)

Answer 3

The sentences are correct or as corrected. But if you are working on, or have learned the demonstrative pronouns celui/celle/ceux/celles, then you can apply them to avoid repeating the subject in the same sentence.
For example, the first sentence could have been replaced by:
"La bibliothèque à New York est plus grande que celle à Paris."
Note:
celui: masc. sing.
celle: fem. sing.
ceux: masc. plur.
celles: fem. plur.
