Explanation please ? Why C is not the answer ?

Hi this is a good concept to test parallelism and ellipses concept.

Here is the original question

In order to improve reliability, Hyundai has used corrosion resistant coating on the inner body on the surface of Sonata; Hyundai's frames have been built to last and they are.

(A) have been built to last and they are
(B) are now built to last and they do
(C) are built to last and they have
(D) had been built to last and they have
(E) are being built to last and they do

Notice that there second sentence starts after a semicolon that means that the second sentence has to be an independent clause.

So per the original sentence the meaning is that coating results in improved reliability. The frames are made to last longer and indeed they do last.

So the sentence and verbs should be in the same tense and they should follow parallelism.

A is incorrect. If you complete the sentence it will read as " have been built to last and they are last". Notice the "last ". It does not make sense rather it should be they do last. So A is incorrect.

B correct.
C Tense changes and still parallelism is not good.
D There is no need to have past perfect tense. Per this choice the cars were made a long time ago and they are not making these cars anymore.
E Being is not good here. We just need a simple present to convey our idea.

Why is option C incorrect
C says:

Hyundai's frames are built to last and they have.

They have what? They have lasted; they have been lasting or something else?

In general, we are allowed to use ellipsis ("assume" words), only when there is no element of ambiguity in terms of interpretation.

Also note that "do" (in correct option B) is a proper "verb". It is interesting to note that do/does/did can stand for the main verb in the sentence: the main verb can be in any tense, but do/does depict the main verb in "simple present" tense, while did depicts the main verb in "simple past" tense.

By the way, the sentence under consideration seems to have been inspired by this official question.

p.s. Our book EducationAisle Sentence Correction Nirvana discusses this property of "to do" forms of the verb. Have attached the corresponding section of the book, for your reference.

Hello Sejal16,

We hope this finds you well.

Having gone through the question and your query, we believe we can resolve your doubt.

As EducationAisle has written, ellipses can only be used when there is no sense of ambiguity and the omitted verb has already appeared in the sentence.

Further, Option C also appears to use the present perfect tense verb "have (lasted)" to refer to a habitual action or information that is permanent in nature; remember, habitual actions and information that is permanent in nature are best conveyed through the simple present tense, and the present perfect tense (marked by the use of the helping verb “has/have”) is used to describe events that concluded in the past but continue to affect the present.

To understand the concept of "Simple Tenses" on GMAT, you may want to watch the following video (~1 minute):



To understand the concept of "Present Perfect Tense" on GMAT, you may want to watch the following video (~2 minutes):



All the best!
