The correct answer is interpersonal; linguistic

First, she can't easily make friends, so she lacks interpersonal intelligence - the one that determines how good we are understanding the  inter-personal, that is "between persons"  relationships.

Second, she is good at reading, so presumably she is good at language - that is linguistic intelligence.
