premise: People are working with some white pipes.
hypothesis: Men are fixing the pipes.
explanation_1: People are not assumed to be men.  Working with pipes does not necessarily imply they are fixing them.
explanation_2: Just because people are working with it does not mean men are fixing the pipes.
explanation_3: people are not always men and working on something does not always result in it being fixed.
