C means to convey the meaning that feeding on the decaying flesh and pulling with its mouthparts are different events. Whereas, the "pulling with the mouthparts" part is actually modifying the clause "feed on decaying flesh". That is, it is explaining how it feeds.

I think you would be able to appreciate the difference between:

He crossed the finish line, limping on one leg. and (He was limping while crossing the finish line)
He crossed the finish line and limped on one leg. (He limped after crossing the finish line)

Hi Ivy, E is wrong because those two actions should not be parallel.

Used by many natural history museum curators in the preparation of animal skeletons for display, dermestid beetles feed on the decaying flesh of animal carcasses, pulling with its mouthparts to strip the bone of any residual fat or muscle tissu

The idea is is to present how the beetle feeds ( Comma + ING modifier ), not to present two parallel actions.

If the sentence were "the beetle feeds on the flesh and sleeps ..." in this case those two actions should be parallel, they express what the beetle can do.
In this sentence however the structure is "the beetle feeds, (HOW it feeds) pulling ".

D. the dermestid beetle feeds on the decaying flesh of animal carcasses, pulling
E. the dermestid beetle feeds on the decaying flesh of animal carcasses and it pulls

Hope it's clear

Hi there,

Used by many natural history museum curators in the preparation of animal skeletons for display, dermestid beetles feed on the decaying flesh of animal carcasses, pulling with its mouthparts to strip the bone of any residual fat or muscle tissue.

Meaning Analysis: The curators use dermestid beetles in the preparation of animal skeletons for display because these beetles feed on flesh and by doing so, they pull the fat out of the bone.

Error Analysis: Notice this phrase in the non-underlined portion of the sentence – “…with its mouthparts…”. Singular pronoun “its” does not agree in number with its plural antecedent “dermestid beetles”. Hence, this antecedent must be changed to singular.

POE:

A. dermestid beetles feed on the decaying flesh of animal carcasses, pulling: Incorrect for the reason stated above.

B. dermestid beetles feed on the decaying flesh of animal carcasses and pull: Incorrect.
1. Same pronoun antecedent number agreement error.
2. The unintentional parallelism between “feed” and “pull” now separates these two activities as independent. It fails to connect the pulling with feeding.

C. the dermestid beetle feeds on the decaying flesh of animal carcasses and pulls: Incorrect. Same parallelism error as in choice B.

D. the dermestid beetle feeds on the decaying flesh of animal carcasses, pulling: Correct.

E. the dermestid beetle feeds on the decaying flesh of animal carcasses and it pulls: Incorrect.
1. Same parallelism error as in Choice B.
2. Pronoun “it” is not needed.

Hope this helps. :)
Thanks.
Shraddha.

The possessive pronoun 'its’ indicates that the subject must be singular. Hence A and B are out.

In C, the expression ‘in order to pull’ is altered intent.. It implies that the beetle feeds on the decaying flesh in order to pull. E flouts the llism norm by redundantly using the pronoun ‘it’. D is the correct choice.

The OA does not make sense. D should be correct as 'its' refers to singular noun.

I don't agree with the OA.
What's the problem with C in which it is stated that the beetle feeds on decaying flesh and pulls with its mouthparts to strip the bone of any residual fat or muscle tissue.
Any idea where I am going wrong.

In this problem, there are two main issues:

1. AB / CDE
plural / singular

The non-underlined portion refers to "its mouthparts", telling us that beetle must be singular. Eliminate A and B.

2. C / D / E
and pulls / , pulling / and it pulls
Feeding is the main action. Pulling fat and muscle tissue is part of the feeding process. The "ing" form of pulling in D makes this clear (we read everything after the comma as a modifier of the main action). In C and E, the conjunction plus main verb construction (and pulls or and it pulls) makes it sound like pulling is a separate action from feeding. This is incorrect. Hence C and E are wrong.
here's more about the comma + -ing modifier:
the "comma + ing" modifier should only be used when:

(A)
it MODIFIES THE ENTIRE ACTION of the preceding clause, and it APPLIES TO THE SUBJECT of that clause;

AND

(B)
one of the following is true:
(1) the "ing" action is SIMULTANEOUS with the main action;
- i ran down the sidewalk, flapping my arms wildly
(2) the "ing" action is a DIRECT CONSEQUENCE of the main action.
- i got a 100 on the most recent exam, bringing my average up to 91

another example:

joe ran down the sidewalk, flailing his arms.
--> correct (simultaneous)

my cousin took extra classes every semester in college, graduating in three years.
--> correct, because the "ing" is an actual consequence of the first action.

my cousin ate frozen food every day in college, graduating in three years.
--> incorrect, because there is no relationship (in particular, the second thing is not a consequence of the first thing, and isn't simultaneous either)

OA is definitely not A. Between D & E.

Shouldn't the parallelism be maintained between feed & pull? Not decaying and pulling? Pulling is done by the beetles right? and flesh is decaying. So D should be incorrect as well. Also, E is wrong because it is breaking parallelism by adding "it"

Can someone please explain this?

OA is "D"

- A & B - pronoun antecendant number error.

- C - in order to pull - changes in the meaning of the sentence.

- E - Changes the meaning by using the connector "and". The intent is to provide extra information and NOT to join two different activities.

D. the dermestid beetle feeds on the decaying flesh of animal carcasses, pulling

"Used by....display" modifies dermestid beetles , so it is preferred to have Dermiestid beetle immediately after comma. So C , D and E gets eliminated .

A --> decaying and pulling --> parallelism is followed
B--> decaying and pull -->parallelism is violated

Yep, actually, choice D is preferable over C as MacFauz said. Pulling.. is the modifier of the action feed on the decaying flesh.

A & B are both wrong for using the plural. "with its mouthparts" is in singular form and hence "the dermistid beetle" is correct

What I feel is that feeding on flesh and pulling to strip the bone are two independent things. The words "any residual" at the end is forcing me to think this way. The "any residual" is sufficient to strengthen my point that though beetle feeds on decaying flesh but it also pulls to strip the bone of any residual fat.

That would change the meaning of the original sentence. Unless there is no option which is grammatically correct and does not change the meaning, we always want to stick to what the original sentence means to say.

Hi @Marcab,

Let’s reason it out if feeding and pulling are two independent activities done by the beetles. The beetles feed on the decaying flesh of animal dead bodies. They pull out any residual fat or muscle tissue left on the bone from their mouthparts. And why do they pull any residual fat? They do so to feed themselves. This is how they eat. If the beetles are not hungry, they will not nibble on the body. So the verb-ing modifier “pulling” is telling us how these beetles feed themselves. Hence both these activities are related in that “pulling” is explaining how the beetles eat.

Hope this helps.
Shraddha
