premise: A group of seven individuals wearing rafting gear, white water raft down a river.
hypothesis: Seven men and women are in a yellow boat.
explanation_1: Individuals does not necessarily imply a mix of men and women.  White water rafting does not necessarily happen in a yellow boat.
explanation_2: It is not necessary that a group of seven individuals should include both men and women. A group of seven individuals raft down a river doesn't necessarily mean that they are rafting down in a yellow boat.
explanation_3: The seven individuals could have been all one gender, as opposed to men and women. Also, the boat/raft may have been any color other than yellow.
