Which sentence does not contain any errors?
a.
no one else on the team is allowed to use our captain erics' equipment.
b.
let's just say, however, that my sister's friends are very interesting.
c.
my two grandparent's houses are one level, but both have a basement.
d.
i normally do not want to step on anyones' toes.

It is B because all the others have errors 

B is the only sentence that does not contain any errors, because all grammar is used correctly and everything is where it is supposed to be and spelled correctly. Hope this helps ya:)

I’m just thinking something from the top of my head so it may not be much so if weathering didn’t exist, there wouldn’t be anything to break up earth’s crust naturally. so by assumptions, the rocks on earth would be larger than they actually are since there’s nothing to break them up into smaller parts.overall, i’m not really sure, but all i know is that it’ll mess up the rock cycle that we have now.hoped this .
