Error Analysis :
All S-V pair are correct ------ correct
Verb ---- sentence stating fact , so all verbs are in present tense .---correct
Here , In " each of which ..... " modifier .
" Each "is referring to colonies , and " which " is referring to " each " ------- makes perfect sense .
So , at first glance , I could not find any error in original sentence .
POE :
a. no error .
b. " them " could be referring to animals . ----wrong
c. is better than choice a .
d. S-V error , each of them --- singular subject , but "consist " ---plural verb
e. no verb for the subject " each .."
Here my question is :
Choice A as such does not have any error , but choice C is correct as it is better constructed than choice A .
According to gmat-prep explanation , " each ... " is referring to animals ,hence choice A is incorrect , but as per my understanding how an animal can contain a female and worker ?? .
Is my analysis is correct ?? .
Thanks,
