Would you help me with these
1)I come out in a rash if I eat chocolate ("a rash" here means just one rash or means rashes, because it doesn't make any sense "to come out in just one rash"
2)All we gotta do is find the boat that took him (shouldn't be "finding" or "to find"? or it's fine)
It should be a rash, which means all of the affected area/s of skin.
