A March 2000 Census Bureau survey showed that Mexico accounted for more than a quarter of all foreign-born residents of the United States, the largest share for any country to contribute since 1980, when about 30 percent of the country’s foreign-born population was from Germany.

B. the largest share that any country has contributed

Hello folk,

could someone clarify this for me pls:

"Mexico accounted", "about 30 percent of the country’s foreign-born population was from German" - past simple
"the largest share that any country has contributed" - present perfect

is that correct to use present perfect and past simple in this case?

Hi Experts, In option B - Isn't the underlined portion a IC? It has subject largest share that and Verb Has... Im little confused.

The underlined portion is an absolute phrase modifier. An absolute phrase modifier modifies an entire clause in some way and has the structure noun / noun phrase + noun modifier.

Here,

Absolute phrase modifier: the largest share that any country has contributed since 1980. (noun = the largest share, noun modifier = that any country has contributed since 1980).

The above absolute phrase modifier modifies the clause "Mexico accounted for more than a quarter of all foreign-born residents of the United States".

Please let me know if you still have doubt.

Hi daagh sir,
I have doubt-
If a sentence for example- Susan: " My daughter has been dancing everyday since 2001", is quoted by someone else the sentence becomes susan said that her daughter had/ has been dancing everyday since 2001.

Doubt A)- which one is correct, has or had? ( Because the actual question on this thread is from gmat verbal review 2017 question number 203. And the answer key explanation says both are correct)-This is a doubt related sequences of tenses in which we generally shift the action in past. But be if the action is still true can the action be presented in present perfect?

Doubt B) If any both had and has is correct, but we are unaware of the fact is the situation still valid or not ( example- I am not aware is susan daughter still dancing everyday), is there any rule which states that we use HAS>>HAD?

Doubt 1. It may please be remembered that if you use either a past perfect tense (including past perfect progressive) or past tense, then the action is already completed. On the contrary, if there is an iota of doubt whether the action is extended until at least today, then present perfect is required, even if there are two different tenses to describe two-time lines like as in Susan's daughter's case. Had danced or had been dancing are all wrong since the dancing has been occurring since 2001 until today.

Doubt 2. example- I am not aware is Susan daughter still dancing every day) -- Is this your second sentence?

I am not aware whether Susan's daughter is still dancing.
--- All the tenses are is present tense are used properly. So, where is the confusion?

Thank you sir for your response. Just to clarify - even in the sequence of tenses when I am quoting something that was said in past by person X and the event that person X was speaking of was in present perfect with respect to person X, WE SHOULD NOT SHIFT SENTENCE IS PAST PERFECT if we have a smallest doubt that the event is true today also. RIGHT?

I was going by general rule to shift everything 1 step in past. Present---> past, Past ---> past perfect, and future tense (will) ----> conditional (would)

And for DOUBT B) I got the clarity from answer you provided for DOUBT A sir. Thank you for that.

I was able to eliminate option A and C.
But i am stuck at option D and E.
It seems to me that 'having' here correctly modifies the previous clause.
I know it looks wordy, but what exactly is the reason to eliminate D and E.

The word Since in the sentence is an indicator that prefect tenses must be used and so only option B does. Is my reasoning correct?? Thank you

C D and E can be eliminated by a mojority.
Between A and B has to be A.
B is tempting because of the usage of present perfect tense with the usage of " since ". Indeed thats a correct usage, however a thing to notice in B is that usage of verb tense makes it an independent clause, and we must have proper connectivity between two clauses. This is the reason B is incorrect.
A correctly uses modifier correctly to modify a quarter of all foreign-born residents.
On the type of modifier used in A, it seems to me a noun+noun modifier(not 100% sure).

Explanation provided in the Verbal review
B) This form of the appositive is the most efficient way to express the comparison.Depending on when the sentence was written and what the writer intended to express, the verb form could be either had contributed or has contributed.The use of has contributed implies that, from the perspective of the sentence, the comparison between German-born US residents and those from other countries still holds true.
