This looks like a good exercise. 1c. should say "Our class learns..."; our class is a(one) group of people, just like a family is one group of people, so it is singular:)

This worksheet is useful to me as we are learning Pronouns. I do not think that the first answers should be written in capital letters because they do not follow capital letter rules.
