Explanation for Question 47 From the Reading Section on the 2019 October Sat
The question 47 says information in the passage best supports which statement about 2 lignin. So if we look back in the passage here, 3 we can see that there's a piece of evidence that directly supports one of 4 these answer choices. And then we'll talk about some of the other answer choices. 5 So if we look starting in line 37, 6 it says lignin is a very brutal natural polymer. 7 So it needs to be tough. And so this evidence is going to directly 8 correspond to the correct answer in this question, 9 which is going to be answer choice D so it says, 10 and it's unaltered state. It breaks too easily to be used in high-performance thermoplastics. 11 So, like I said, that evidence that we just read that 12 in its natural state. So unaltered and natural here are synonymous. 13 It needs to be tough and it breaks too easily. 14 So it needs to be tough. 15 And it's brittle, I think is what it says in the passage. 16 So brittle is synonymous with breaks too easily. 17 And so it would have to be tough. So like I said, 18 that piece of evidence directly corresponds to this answer choice, 19 but let's talk about some of the other ones. So answer choice a says 20 it is too expensive to use as an industrial polymer without being diluted with 21 more common polymers. So answer choice is going to be incorrect because 22 lignin is actually mentioned in a discussion referencing more economically 23 viable options as opposed to fossil fuels. 24 And you can find that reference in the third parag...
