O, but which is the question?
Tomás y yo leemos unos libros. This is the right response becuase, the common action that people write; when it comes to books, is reading(leer). Also, you're talking in a plural form, becuase you are naming more than one person. That is becuase, it is leemos and not leer. To sum it up, the correct answer is leemos.
What are the options they give you??
