Explanation for Question 30 From the Reading Section on the 2019 March Sat
Question number 30 reads as presented in the passage, 2 the researchers make which assumption about the bionic leaf that has yet to be 3 substantiated. So we are looking for an assumption that they create on 4 something that they're kind of making it a little bit of a leap of 5 faith on that might not necessarily be the case. 6 So we're going to find this towards the end of the passage when the 7 author is talking about potential future applications for this technology. 8 Um, and here we see, 9 um, starting in this third to last paragraph, 10 a lot more discussion of the technology, 11 what it can be used for in the future and those sorts of considerations. 12 So we see at the end of this paragraph, 13 um, you open the door to making many of the natural compounds we rely 14 on every day, and then some examples left listed after that. 15 So this is an example of a really big assumption that the author makes 16 or rather this, um, the speaker that is quoted by the author. 17 Um, it's not necessarily proven through this article that, 18 um, that of bionic leaf can be used to make all of these other 19 different types of compounds. That's not something that's really discussed. 20 So while this is expressed by the passage as an area for future 21 use of this technology, it's not necessarily clear that this will actually function 22 as the speaker says it well. So this lines up really well with answer 23 choice B, which says the leaf can be 24 used to produce chemical compounds oth...
