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

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

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.

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"

Expert's post
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

I can find many reasons why E is wrong mate.....
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.

A. dermestid beetles feed on the decaying flesh of animal carcasses, pulling
B. dermestid beetles feed on the decaying flesh of animal carcasses and pull
C. the dermestid beetle feeds on the decaying flesh of animal carcasses in order to pull
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

Let us use E in the sentence. If you are using 'and' for parallelism, the 'it" after the 'and' is spoiling parallelism.... feeds on______ and pulls with __________ would have been better...
Secondly, if you are using 'and' to state two independent facts... pick the second statement (after and) and see if it is giving you a complete meaning.... it pulls what?
Finally, the big thing... understand the meaning of the sentence..... the beetle feeds on the decaying flesh.. in what way or how? pulling off the meat using its mouthparts.... so since we are explaining how the action is carried out we shouldnot be using 'and'.

Please refer to parallelism concept and your this confusion will not come up again....

Okay This explains it. Thanks!

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.

PULLING..... : is a modifier here. think like this Beetles by pulling......

A. dermestid beetles feed on the decaying flesh of animal carcasses, pulling
(Correct)
B. dermestid beetles feed on the decaying flesh of animal carcasses and pull
(pulling is the modifier part. It answers how beetles do it? by pulling...... ; so not pull)
C. the dermestid beetle feeds on the decaying flesh of animal carcasses in order to pull
(same error as B)
D. the dermestid beetle feeds on the decaying flesh of animal carcasses, pulling
(Wrong: THE dermestid beetle: This uses the word THE. In order ot use THE, noun or subject must unique in the world such as THE SUN, THE USA or it must be referred earlier in the sentence. Both cases are negative)
E. the dermestid beetle feeds on the decaying flesh of animal carcasses and it pulls
(same error as in B)

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

The middle part of sentence is separated by comma pair...thus it is an additional info sentence. Pulling is not in -ing format as comma present
infront of last sentence is from double comma modifier....hence pulling modifies the first sentence ( which does not make sense ).
This concept is used many places..Am I thinking correct ?

Hi,

Pulling is used as a verb-ing modifier only. It tells more info about the preceding clause in comma.
