Hi All,

More than 30 years ago Dr, Barbara McClintock, the Nobel Prize winner, reported that genes can “jump”, as pearls moving mysteriously from one necklace to another.

Image

“Like” and “As”, both are used to convey comparison is a sentence. However, there is a difference between their usages. “Like” is always followed only by a “noun” or a “pronoun” whereas “As” is always followed by a “clause”.

Going by this rule, the original sentence is incorrect because here “as” is not followed by a clause. This error can be rectified either by placing a clause after “as” or by replacing “as” with “like”.

POE:

Choice A: as pearls moving mysteriously from one necklace to another. Incorrect for the reason stated above.

Choice B: like pearls moving mysteriously from one necklace to another. Correct.

Choice C: as pearls do that move from one necklace to others. Incorrect. Firstly, “that” is relative pronoun that modifies a noun. So “that” should touch the noun it modifies. But in this choice, “that” is away. Also, the use of “others” is not correct here. The intended meaning is that pearls move from necklace to another necklace. Using “others” make it ambiguous as to where the pearls move to.

Choice D: like pearls do that move from one necklace to others. Incorrect. Apart from repeating the “that” and “others” errors of choice C, this choice has another error. “like” has been followed by a clause here.

Choice E: as do pearls that move mysteriously from one necklace to some other one. Incorrect. This sentence distorts the meaning of the sentence. By using the modifier "that move" and verb "do" for pearls, it appears that pearls to two actions - pearls jump and by the way these pearls also move mysteriously...This is not the intended meaning. The author actually wants to say that genes jump like the pearls. And then he describes the manner in which these pearls jump - by moving mysteriously.

Image

1. “Like” is followed by a noun and “as” is followed by a clause.
2. Be careful of any change in words that appear in the original sentence.

Hope this helps.
Thanks.

Hi

Would it be correct to claim that "other" and "some other" in some of the options are incorrect because they require nouns after them? e.g. some other JEWELRY

Thanks

Dear mikemcgarry sir

would option C been correct , had one to others been replaced with one another?

Thanks & Regards

Hi sonusaini1,

Thanks generis for tagging me here! Yes, I can respond for Mike :)

It would not make sense to replace "others" with "one another" here:

as pearls do that move mysteriously from one necklace to one another

But it would make sense to replace "others" with "another" (then it is clear that the pearls are moving from one necklace to another necklace). It's not necessary to repeat the noun (necklace), since the parallelism makes it clear:

as pearls do that move mysteriously from one necklace to another

If "others" had been replaced with "another", then C would definitely be a bit better, but it still would be too wordy compared to B (that was the original reason why we eliminated C). The "that" clause in option C is still incorrect, and so B would still be the correct answer in this case.

I hope that helps! :)
