premise: Two people in a dense jungle area with trees and grass everywhere.
hypothesis: A couple are looking for their lost dog.
explanation_1: There are reasons might be in a dense jungle area beyond looking for their lost dog.
explanation_2: Because two people are together does not make them a couple. Being in a dense jungle area does not mean they are looking for their dog.
explanation_3: Two people aren't necessarily a couple. They are in a jungle, but we don't know why, so we don't know that they are looking for anything at all. The fact that we don't know that the two people are a couple and that we don't know if they are looking for something means that we also don't know that they are looking for a lost dog.
