squirrels grow the fastest. She separates thirty young squirrels into two equal groups. She feeds one of the groups nuts and she
feeds the other group insects. The group of squirrels that eats the nuts grows faster than the group of squirrels that eats the insects

A. Are squirrels that eat nuts cuter than squirrels that eat fruit or insects ?
B.
Are squirrels that eat nuts happier than squirrels that eat fruit or insects?
C.
