Leimos el Libra a los ninos

Answer 1

We read the book to the kids (leímos el libro a los niños)

Answer 2

Leimos el Libro a los ninos

Step-by-step explanation:

The verb here is "to read", the subject is "us", and the object here is a "book", the sentence is in past tense.

The only problem here is the gender of the object "Book" which is male, you can check that on the R.A.E. web page.
