zeynep_357, I made some adjustments and set a poll.
before edition:
there are both eagles and snakes in the caps. one of them reached there by soaring the other by groveling. the importance is not where you arrive
If those are plural we have a problem here.
"both" means "two" not "many" and also the second sentence says "One of them....., the other..." which means that we are talking about two animals (one and the other).
