DUKB24

tricky one

notice that this question


each is the subject   ( rare use of each)


the non-underlined portion has a pronoun it


so whatever answers containing all should be eliminated , because the use of all will leave it without any antecedent






the use of with is problematic here


if you construed some as referring to colonies


that doesn't make sense,  colonies cannot have themselves ( you should understand this meaning very literally)


if you construed some as referring to unknown plurals


the sentence is not clear enough( we have no idea what the sentence is trying to say)
