Intellectual students most often find themselves in astounding conditions for some sentence structures. Grammar rules are very competitive as well as flexible, which students can’t apprehend. That’s why GMAT organizes logical tests to assess the potential of scholars on the basis of sentence correction.
The particular rule which we will talk about now is about the concept of sentence structuring from beginning to the ending in the exact same tense. This factor is always very helpful and also appropriate in most of the situations. Irratically placed tenses in an irregular manner in the same sentence seems very illogical.
Ron watches Frozen on repeat and liked it whenlsa sings
This sentence doesn’t add up in a logical way as it jumps from present tense to past tense and ain from past tense to present tense in a unstructured way. In the sentence “watching the movie” is in present tense, but afterwards “liked” is in past tense and at last ain you can see “sings” is in present tense. Hence, tense related to this sentence is changing frequently and unreasonably.
The proper structure which should be given to this particular sentence is-
In present tense
Ron watches Frozen on repeat and likes it when Elsa sings.
In Past tense
Ron watched Frozen on repeat and liked it when Elsa sang.
Moreover, both the sentences are cohesive in nature that gives an illustration of Ron’s prospect on movies based upon eminent animation.
An example is given below which will help you to get frequent about varying verb tenses. This will help you throughout your GMAT tests and expertise on sentence correction.
Attempts to standardize healthcare, an important issue to both state and national officials, has not eliminated the difference in the quality of care existing between upper and lower income families.
(A) Has not eliminated the difference in the quality of care existing
(B) Has not been making a difference eliminating the quality of care that exists
(C) Has not made an elimination in the quality of care that exists
(D) Have not eliminated the difference in the quality of care that exists
(E) Have not been making a difference eliminating the quality of care existing
This sentence has more than one topic regarding the errors which you should recognize. “…an important issue….” is actually a modifier which generally is mistreated by students despite the subject. Therefore, basically the sentence comprehends “Attempts to standardize healthcare has not eliminated…..” and it put emphasis on the actuality that is- “attempts” is key subject and as a result the verb should be plural in place of singular.
By all these deductions, one thing is sure that the answer options A, B and C should be eradicated. So, the appropriate answer will be remaining choices D or E.
As you can notice, there are verb tense differences lies within the answer choices D and E. In the choice D, the whole sentence illustrates subjects in the past however the result is implicated in the present which is a blunder in the stucture of the sentence. But, you can’t just eliminate this option as it seems logical rather go for a comparison between choice D and E. In option E, you can find persuasive feeling since the cerb is actually a participle, it means existing in nature. Though, original meaning of the sentence seems different and unintended. As a result you should eliminate option E and the answer is choice D.
