Explanation for Question 31 From the Reading Section on the 2019 March Sat
All right. Uh, question number 31 is asking us for evidence 2 in favor of the answer to question number 30. 3 If you recall from question 30, we were looking at an assumption about the 4 bionic leaf that has yet to be substantiated. 5 So we're going to go through these answer choices for 31 lines supported to 6 47, 48 to 52 53 to 56 and 56 to 60. 7 And see which of those speaks to an assumption that the author is making, 8 then they aren't really backing up too well. 9 So let's take a look at answer choice, eye lines, 10 40 to 47. First 40 to 47 is here. 11 Um, the bacteria combine the hydrogen with carbon dioxide as they divide 12 to make more cells and then, 13 um, produce isopropanol, which can be burned in engine. 14 So this is just an explanation of the process. 15 It's not really an assumption that isn't being backed up. 16 So answer choice a is out answer choice. 17 B is lines 48 to 52. 18 That's here. The advantage of interfacing the inorganic catalyst with biology is that you 19 have an unprecedented platform for chemical synthesis. 20 So this is a perspective expressed by this speaker. 21 Um, and it's something that is not necessarily unsubstantiated since 22 we've seen evidence that there are advantages to this technique and that 23 there are a lot of opportunities arising from the technology that was used to 24 make the bionic leaf. So we can eliminate B as well. 25 Choice C is lines 53 to 56. 26 So that's here. Um, life has evolved for billions of years to produc...
