still not sure why D is wrong. gramatically it looks fine. IMO, the law stopped the immigration because it introduced the literacy requirement and this helped in halting of the immigrants. why is D wrong?
It is my suspicion that this is an unfair question. It requires too much specific contextual knowledge. However, we can still practice the interpretation of *meaning* here.
Quote:
The Immigration Act of 1917 halted immigration from most Asian countries into the United States by imposing a literacy requirement for immigrants entering the country.
This version of the sentence says the literary requirement was the method by which the law halted immigration.
Quote:
The Immigration Act of 1917 halted immigration from most Asian countries into the United States and imposed a literacy requirement for immigrants entering the country.
This version of the sentence says the act did two things: halted immigration of most Asian countries, AND imposed a literary requirement for immigrants entering the country.
Let's consider some simpler sentences:
In his biathlon, he swam half a mile by running a half marathon.
In his biathlon, he swam half a mile and ran a half marathon.
Here, the second must be correct. The first is not technically grammatically wrong, it just says that running is the method he used to swim... that makes no sense. Now consider this pair:
She trained for his marathon by running 20 miles every week.
She trained for his marathon and ran 20 miles every week.
Here the FIRST sentence must be right. The '20 miles a week' is clearly how this person trained for her marathon. The second sentence says two things she did, but their relation to each other is not nearly as strong.
So in this sentence, we need to ask if the literacy requirement is HOW immigration from Asian countries was halted. Again, this requires a lot of outside knowledge--too much for a GMAT question, I think--to say 'no.'
Immigration being halted from 'most Asian countries' means you could not immigrate from certain *countries*. The only way a literacy requirement could stop immigration from a whole country is if the entire country was not literate in English. That just won't be the case. More likely the law simply halted immigration from that country--"No immigrants allowed from Malaysia"--and also imposed literacy requirements for all immigrants.
If the sentence said "The Immigration Act of 1917 prevented most Asian immigrants from entering into the United States by imposing a literacy requirement for immigrants entering the country" we might have a different story. A literacy requirement could conceivably stop most IMMIGRANTS. But it would not halt immigration from COUNTRIES.
Again, I think this is too much outside knowledge for an official question. But do note--I'm using some pretty rock-solid GMAT SC skills to pinpoint *why* it's not a fair question. In order to use my outside knowledge to explain why D's meaning isn't quite right, I have to be super specific on what D's meaning *is*: these 'literacy requirements' someone halt immigration from WHOLE COUNTRIES, as if EVERYONE IN THE COUNTRY IS ILLITERATE IN ENGLISH. My experiential knowledge tells me there's no way that's feasible.
I also would note, I disagree with some of the explanations in this thread. For example, while it's common to say an answer is wrong because it 'changes the meaning of the sentence,' that's not really why an answer is wrong. The original sentence's meaning sometimes *must* be changed. Better is to say the meaning of a sentence is ILLOGICAL or clearly doesn't capture the sentences INTENDED MEANING (and intended meaning comes from the *whole question*, not just the sentence as written).
I also disagree that the GMAT 'prefers' parallelism. There are times, and questions, where grammatically correct parallelism is incorrect because the meaning within the structure is wrong. See the questions above with the 'biathlon' and 'marathon.' Parallelism is right in one and wrong on the other, and it's purely meaning that determines which.
