The bridge oscillated vigorously under the fluctuating load of the oncoming vehicles,  the faulty load bearing mechanisms unable to damp down its vibrational energy, and was  on the verge of collapse.

A. the faulty load bearing mechanisms unable to damp down its vibrational energy, and was

The bridge was unable to damp down its vibrational energy not the faulty load bearing mechanisms

B. unable to damp down its vibrational energy by the faulty load bearing mechanisms and

Correct

C. the faulty load bearing mechanisms were unable to damp down its vibrational energy and were

Two independent clause joined by comma makes this is a run on sentence

D. it was unable to damp down its vibrational energy by the faulty load bearing mechanisms and was

Two independent clause joined by comma makes this is a run on sentence

E. the faulty load bearing mechanisms were unable to damp down its vibrational energy, was

its can refer to the bridge or to the load bearing. Hence we can eliminate this

IMO B

S1905 · Answer

A. the faulty load bearing mechanisms unable to damp down  its  vibrational energy,  and was - INCORRECT
- ambiguous pronoun antecedent: 'its' can refer to the bridge or the fault load bearing

B. unable to damp down  its  vibrational energy by the faulty load bearing mechanisms  and  -  CORRECT 
-its correctly refers to the bridge

C. the  faulty load bearing mechanisms were  unable to damp down its vibrational energy and  were  - INCORRECT
- Two independent clauses cannot be separated by just a comma: comma + FANBOYS required in such cases
- The meaning has changed - 'was' was intended for the bridge but here 'were' refers back to mechanisms - does not make sense

D.  it was  unable to damp down its vibrational energy by the faulty load bearing mechanisms  and was  - INCORRECT
- Two independent clauses cannot be separated by just a comma: comma + FANBOYS required in such cases

E.  the faulty load bearing mechanisms were  unable to damp down its vibrational energy,  was  - INCORRECT
- Two independent clauses cannot be separated by just a comma: comma + FANBOYS required in such cases
- 'and' required before 'was' -> The bridge oscillated vigorously AND was on the verge of collapse

Papai21 · Answer

We see that three things happened to the bridge in the past. The bridge oscillated. It was not able to stop the vibration. It was on the verge of collapse.
So we need to have all these in parallel and in past tense. Hence a "was" is required to make the underlined part parallel.
Thus answer choice (D) IMO

sanjitscorps18 · Answer

A. the faulty load bearing mechanisms unable to damp down its vibrational energy, and was
 --> Looks okay. Direct explanation for the oscillations are mentioned

B. unable to damp down its vibrational energy by the faulty load bearing mechanisms and
--> this suggests that the faulty load bearing mechanism was not able to do its job properly. HaHa!!

C. the faulty load bearing mechanisms were unable to damp down its vibrational energy and were
--> Comma splice, two independent clauses connected by a comma

D. it was unable to damp down its vibrational energy by the faulty load bearing mechanisms and was
--> 'it was' is an incorrect phrase beginning for a dependent clause. No comma before and at the end

E. the faulty load bearing mechanisms were unable to damp down its vibrational energy, was
--> there should be an "and" before was at the end

IMHO Option A

rajtare · Answer

akash2703 · Answer

Imo D

The bridge oscillated vigorously under the fluctuating load of the oncoming vehicles, the faulty load bearing mechanisms unable to damp down its vibrational energy, and was on the verge of collapse.

A. the faulty load bearing mechanisms unable to damp down its vibrational energy, and was
 Wrong meaning due to the (comma + and) construction, making a list of 3 independent items.
 
B. unable to damp down its vibrational energy by the faulty load bearing mechanisms and
 on the verge of collapse is parallel to under the fluctuating load of the oncoming vehicles. 
Distorts the meaning - The bridge oscillated vigorously on the verge of collapse.

C. the faulty load bearing mechanisms were unable to damp down its vibrational energy and were
 Run on sentence.
Parallelism issue: the faulty load bearing mechanisms were on the verge of collapse. Doesn't make sense.

D. it was unable to damp down its vibrational energy by the faulty load bearing mechanisms and was
 Correct. At first it looks like a run on but this whole clause is a modifier, modifying the bridge.

E. the faulty load bearing mechanisms were unable to damp down its vibrational energy, was
 The bridge oscillated vigorously under the fluctuating load of the oncoming vehicles,  the faulty load bearing mechanisms were unable to damp down its vibrational energy , was
Two main verbs in a sentence without a conjunction. Incorrect

Kushchokhani · Answer

"vibrational energy by the faulty load bearing mechanisms" is incorrect. vibrational energy is of the bridge. Hence, B and D are out. Also, D is a comma splice.
the faulty load bearing mechanisms were on the verge of collapse? No, it was the bridge that was on the verge of collapse. Also, this sentence is a comma splice. Hence, C is out.
E is comma splice, hence incorrect.
Answer is A.

GoalEver · Answer

Answer B for me.

A. the faulty load bearing mechanisms unable to damp down its vibrational energy, and was => the faulty load has nothing to do with the subject of the beginning of the sentence ( the bridge) so NO.

B. unable to damp down its vibrational energy by the faulty load bearing mechanisms and => yes the bridge was unable to....

C. the faulty load bearing mechanisms were unable to damp down its vibrational energy and were => the mechanisms were not on the verge to collapse, non sense.

D. it was unable to damp down its vibrational energy by the faulty load bearing mechanisms and was => Run-on sentence

E. the faulty load bearing mechanisms were unable to damp down its vibrational energy, was => same as A

So Answer B.

manish1708 · Answer

Answer: A

The bridge oscillated vigorously under the fluctuating load of the oncoming vehicles,  the faulty load bearing mechanisms unable to damp down its vibrational energy, and was  on the verge of collapse.

A. the faulty load bearing mechanisms unable to damp down its vibrational energy, and was  -->  Correct . first underlined clause properly justifies on why bridge is oscillating. The bridge oscillated... and was... are parallel and SV agreement is maintained.

B. unable to damp down its vibrational energy by the faulty load bearing mechanisms and  --> Incorrect. by the is the issue. this changes the meaning. unable to damp down vibrational energy is due to faulty load bearing mechanisms and not by using those mechanisms.

C. the faulty load bearing mechanisms were unable to damp down its vibrational energy and were  --> Incorrect. Bridge is singular, requires singular verb was and not were.

D. it was unable to damp down its vibrational energy by the faulty load bearing mechanisms and was  --> Incorrect. meaning implies that faulty load bearing mechanism is used to damp down vibrational energy. instead of by, due to would be better.
 
E. the faulty load bearing mechanisms were unable to damp down its vibrational energy, was  --> Incorrect. connector is required before was. comma was on...cannot stand by itself.

Fido10 · Answer

The correct answer is A

A. the faulty load bearing mechanisms unable to damp down its vibrational energy, and was 
This is the correct answer, additional infos are put between two comas, and then the twco independant clauses are linked by a coma + "an" 
 B. unable to damp down its vibrational energy by the faulty load bearing mechanisms and 
This answer is very wordy, 
 C. the faulty load bearing mechanisms were unable to damp down its vibrational energy and were 
It is the bridge that whas on the verge to collapse not the loadbearing mechanisms, Wrong answer
D. it was unable to damp down its vibrational energy by the faulty load bearing mechanisms and was
this clause "The bridge oscillated vigorously under the fluctuating load of the oncoming vehicles" and this clause " it was unable to damp down its vibrational energy" are not linked correctly, it should be a coma + "and", Wrong answer
 E. the faulty load bearing mechanisms were unable to damp down its vibrational energy, was 
We need "and" + a coma to connect the two independent clauses, not just a coma + verb, Wrong answer

av1901 · Answer

A. the faulty load bearing mechanisms unable to damp down its vibrational energy, and was
 Correct, the faulty load bearing mechanisms correctly referenced as unable to damp down its (singular referring to bridge as mechanisms is plural so no ambiguity) and the use of 'and was' also correct. ANSWER

B. unable to damp down its vibrational energy by the faulty load bearing mechanisms and 
 The faulty load bearing mechanisms are unable to damp down, not bridge unable to damp down by the mechanisms. ELIMINATE

C. the faulty load bearing mechanisms were unable to damp down its vibrational energy and were
 Subject verb agreement error leading to meaning error. This indicates that the faulty load bearing mechanisms were on the verge of collapse which is incorrect because it is the bridge which was on the verge of collapse. ELIMINATE

D. it was unable to damp down its vibrational energy by the faulty load bearing mechanisms and was
 Same reasoning as B. ELIMINATE

E. the faulty load bearing mechanisms were unable to damp down its vibrational energy, was
 Missing an 'and' before was. If there was a comma after 'bridge' then it would have made sense but not now. ELIMINATE

A.  the faulty load bearing mechanisms unable to damp down  its vibrational energy,  and was 
 Correct modifier usage..'and was' can be attributed correctly to the 'bridge'

B. unable to damp down its vibrational energy by the faulty load bearing mechanisms and  (was) 
 no main verb in the second independent clause

C. the faulty load bearing mechanisms were unable to damp down its vibrational energy and  were 
 Singular verb 'was' will be correct , since it refers to only one bridge

D.  it was unable  to damp down its vibrational energy by the faulty load bearing mechanisms and was
 Redundant structure..hence incorrect

Bunuel   angelscry97   bb

The reasoning in official explanation is matching with my reasoning above. I have just mentioned it briefly. May I please know exact reason for not getting kudos for this one so that I better take that into account for my upcoming explanations?

bb · Answer

Hi. I usually look for the explanation of the correct answer. However, since this is an SC, and you have used a POE, technically explanation of the correct answer is not necessary though you could say "A is correct as written" to be super clear in the future. I gave you kudos. They will be accounted for in the points within an hour. P.S. Please always clearly indicate why a certain answer is correct or incorrect and clearly mark the final answer
