Answer 1

Those questions may make sense in a different language, but what they're supposed to mean in English is almost impossible to understand.

It matters a lot that people help eachother.  If we did this then there would be no need for competition.  A lot less poor, animosity, and envy.  Also when one is hurt, they can be cured, helped or saved as well.
