Passage Summary: A psychologist says little kids don't realize animals have feelings until they're older, so we shouldn't let them have pets until they hit that age.

Conclusion: Most children should not be given pets until they reach at least six years of age.

Reasoning: Children under six generally lack an understanding of animals' feelings and needs, viewing them selfishly instead.

Analysis: There is a significant gap between 'not understanding an animal's feelings' and 'should not have a pet.' The argument assumes that understanding an animal's needs is a strict requirement for pet ownership. To make this conclusion follow logically, we need a premise that says if a child cannot understand an animal's feelings, they should not have one. Look for an answer that explicitly links the psychological capacity for empathy to the appropriateness of having a pet.
