To me, D is the very obvious choice

A, C and E can be easily eliminated

A - it is not clear what the "of them" refers to
C, E - "that" and "which" are incorrect - we need "of"

B contains a fair bit of unclear language.
"each with several breeding females" - each what? Each colony? Each animal?
"and their pups" - whose pups?

D is much more clearly written although personally I would right 'females who' rather than 'females that'

I find solving through the options easier. I use the stimulus to figure out the meaning and try to look for obviously glaring errors. Solving through the options is easier and simplifies the POE to a greater extent.

(A) : "them" usage is ambiguous. I see it referring to coteries or colonies or prairie dogs. You take your bet. Eliminated.

(C) has the same issue as (A). Eliminate (C).

We are left with (B) (D) and (E).

In (B) , "and their new pups" , their refers to what here .. coteries or breeding males. Eliminate (B).

Between (D) and (E), I would choose (D) because the "of roughly a dozen" concisely explains my point, although I see the official explanation pointing to a comma splice in (E). I missed that in the crunch of the situation.

, consisting in option D what does it refer to

comma + Verb ing : how aspect or result of the previous clause. But here representing colonies.( how can you consider this as correct )

verb+ing can represent immediate noun preceding it without comma but here case is different.

Please suggest me if my understanding have any gaps.

Prairie dogs live in tight-knit colonies, called coteries, of roughly a dozen of them, that consist of several breeding females that often stay together for their entire lives, one or two breeding males that tend to switch coteries frequently, and their new pups.

A. of roughly a dozen of them, that consist of several breeding females that often stay together for their entire lives, one or two breeding males that tend to switch coteries frequently, and their new pups.
B. of roughly a dozen animals, each with several breeding females that often stay together for their entire lives, one or two breeding males that switch coteries frequently, and their new pups.
C. that have roughly a dozen of them, with several breeding females that often stay together for their entire lives, one or two breeding males that tend to switch coteries frequently, and the females’ new pups.
D. of roughly a dozen, consisting of several breeding females that often stay together for their entire lives, one or two breeding males that tend to switch coteries frequently, and the females’ new pups.
E. with roughly a dozen animals, each coterie includes several breeding females that often stay together for their entire lives, one or two breeding males that tend to switch coteries frequently, and the females’ new pups.

This is a tricky one..!!

One way you approach this question is to know that most of the times, modifiers inside double commas can be removable and the sentence should still be logical and grammatically correct. Doing exactly that, we have this :

A. Prairie dogs live in tight-knit colonies that consist of several breeding females that often stay together for their entire lives, one or two breeding males that tend to switch coteries frequently, and their new pups. : At first read, seems ok but notice "their" is not clarified here. whose pups are those? females? males? i do not know.
B. Prairie dogs live in tight-knit colonies each with several breeding females that often stay together for their entire lives, one or two breeding males that switch coteries frequently, and their new pups. : Illogical, ELIMINATE
C. Prairie dogs live in tight-knit colonies with several breeding females that often stay together for their entire lives, one or two breeding males that tend to switch coteries frequently, and the females’ new pups. : They are staying in colonies with other animals?? ELIMINATE
D. Prairie dogs live in tight-knit colonies consisting of several breeding females that often stay together for their entire lives, one or two breeding males that tend to switch coteries frequently, and the females’ new pups. : Seems fine. confusing "their" is removed here. Should be correct. lets check E
E. Prairie dogs live in tight-knit colonies each coterie includes several breeding females that often stay together for their entire lives, one or two breeding males that tend to switch coteries frequently, and the females’ new pups.: Illogical, ELIMINATE

So we have D as our answer ..!!

I think it means two independent sentences cannot be connected with just a comma. before 'each' , there should be a semicolon or fullstop.

V Good question:
1. In such complex problems, always try to find the obvious differences among the answer options.
2. Check for SV errors and meaning errors.
3. Words like “them”, “it”, “their”, “each” etc must have proper logical antecedents. (A, B, C out)
4. Always prefer NOUN+NOUN modifier (as in end of option C,D,E)
5. Watch out of comma splice errors (Two independent complete sentences cannot be connected by using just a comma). Option E out.


Final answer: D

Final answer: D

What are 2 independent clauses here? can you please explain? There is comma in all the options, why it is an issue only in option E
