classic Subject Verb agreement + parallelism question

E satisfies both - "The number"is parallel to "has".
"The number of ..."is parallel to "the number

though E is the best out of the lot but i find the ellipses in E rather weird

The number of car accidents caused by faulty brakes, like the number caused by faulty wiring, has increased significantly since regulations on manufacturing were relaxed.

firstly whats bothering me the comparison .secondly,and more importantly, the following ellipses is little disturbing

The number of car accidents caused by faulty brakes, like the number( of accident ) caused by faulty wiring, has increased significantly since regulations on manufacturing were relaxed.

EXPLAIN the correct answer as well as why other options are wrong..


HERE IS OE

The original sentence contains several errors. First, it is incorrect to refer to "the amount of car accidents" because "amount of" is used only with uncountable quantities, such as “amount of salt.” Since accidents are countable, the correct quantity reference is "the number of car accidents." Second, the original sentence compares “the amount of accidents” to “accidents caused by faulty wiring.” The correct (i.e., logically and structurally parallel) comparison is between the number of one type of accident and the number of another type of accident. Third, the present perfect "have been relaxed" is incorrectly used. This action occurred exclusively in the past, so the simple past "were relaxed" is needed.

(A) This choice is incorrect as it repeats the original sentence.

(B) First, it is incorrect to refer to "the amount of car accidents" because "amount of" is used only with uncountable quantities, such as “amount of salt.” Since accidents are countable, the correct quantity reference is "the number of car accidents." Second, this choice compares “the amount of accidents” to “accidents caused by faulty wiring.” The correct (i.e., logically and structurally parallel) comparison is between the number of one type of accident and the number of another type of accident. Finally, the antecedent of the plural pronoun “those” is ambiguous: it could refer to “car accidents” or “faulty brakes.”

(C) The plural verb “have increased” does not agree with the singular subject “the number.”

(D) This choice compares “the number of car accidents caused by faulty brakes” to “accidents caused by faulty wiring.” The correct (i.e., logically and structurally parallel) comparison is between “the number of car accidents caused by faulty brakes” to “the number of car accidents caused by faulty wiring.” Third, the past perfect "had been relaxed" can only be correctly used to indicate that the regulations were relaxed prior to some other action in the past. In this sentence, there is no other past action, so the use of the past perfect tense cannot be justified and the simple past "were relaxed" should be used instead.

(E) CORRECT. “The number” is correctly used to refer to car accidents, a countable quantity. Also, a logically and structurally parallel comparison is made between “the number of car accidents caused by faulty brakes” to “the number caused by faulty wiring.” Finally, this choice uses the correct simple past “were relaxed.”

QUESTION: Why is "have been" relaxed incorrect? The regulations are still relaxed, but why is "have been" incorrect? Why do we have to use "were"?

Thanks.


Were is correct because the regulations are relaxed only on a particular date say on 1.1.2010 but the effects are experienced for some time span in future.....


So we will say that ""since regulations on manufacturing were relaxed""...


That's precisely it! If the effects are still experienced in the future it doesn't matter whether the regulations were relaxed only on a particular date. You still need to use the present perfect to account for that continued effect, described clearly by the use of the word since.

I am not saying that this is the correct answer because it has other mistakes, but it hard to understand why the use of have been in incorrect for this particular answer choice.

Anyone wants to win some kuddos?

Amount (Singular) 'HAS' increased B,C are out right off the bat.
Comparison has to be "The Number" vs. "The Number"
Only E does this job correctly.
You don't even need to look at the last part of the sentence, were relaxed but just to check.
Has increased significantly since regulations WERE relaxed is the correct verb tense.
