Explanation for Question 42 From the Writing Section on the 2020 October Sat
So question 42 is asking us, which answer choice puts emphasis on carbon and 2 makes the oxygen and the hydrogen not look as important right now. 3 If we look at question or answer twice a, we see that carbon atoms 4 are placed in the forefront, the sentence, 5 their first thing that said, but also we put the oxygen and the hydrogen 6 inside of this phrase that set off in dashes, 7 right? And this is called an a positive phrase. 8 And these are non-essential essential phrases that we put off in dashes or sometimes 9 in commas. And they basically say that whatever's in here is not essential to 10 the sentence and by putting oxygen and hydrogen and the non essential part, 11 we're basically saying that they're not as important as the carbon, 12 which is consistent with what the, what the question wanted us to say. 13 Now, if we look at BBC that says carbon oxygen and hydrogen, 14 and here carbon has said first, that's true, but oxygen and hydrogen are in 15 the normal part of the sentence, whereas an a they're set off into a 16 non-essential part. 17 So be as not as good as in the answers, 18 a because oxygen hydrogen, hydrogen still seems somewhat important in answer 19 choice B. Now C says the frame of the sugar had used not only 20 carbon, but also oxygen and hydrogen, 21 the way the sentence is written, it actually puts more emphasis on the oxygen 22 and hydrogen by saying that they use them in addition to carbon. 23 Right? So see it as the opposite of what we want. 24 And finally, D in conjunction with the carbon atoms, 25 we also use oxygen and hydrogen. 26 This is similar to seeing that there's at least equal emphasis on both 27 of these answer choices on both the oxygen and the hydrogen and the carbon, 28 if not more emphasis on the oxygen and the hydrogen, 29 which is again, not what we want. So our best answer here is going 30 to be a, because we set the oxygen and the hydrogen off in the 31 positive phrase,
