I'm not a native English speaker. We were supposed to use the verb *be* instead of the verb *belong* using possessive pronouns. The question is - *Do those toys belong to her?* The answer given by some is - *Do those toys are hers?* Isn't it simpler to say: - *Are those toys hers?* Sorry for bringing a confusing issue and not stating it properly. Thanks a lot. I appreciate your concern very much. I enjoy learning English.
