Explanation for Question 26 From the Reading Section on the 2019 October Sat
Question 26 says which choice provides the best evidence for the answer to the 2 previous question. And we determined in an earlier video that the correct answer to 3 the previous question question 25 is going to be answer choice a that 4 the passage must strongly suggest that there is a relationship between the presence of 5 plants rooted near rivers and the size and composition of particles from vegetation and 6 rocks. So let's look at the lines of evidence given to us as answer 7 choices in question 26 and see which one best supports this idea. 8 The elements that we're looking for here is the relationship between plants rooted near 9 rivers. So any mention of that, 10 and we're looking for the size or composition of particles. 11 So if we start with answer choice a, 12 it says as soon as the plant's got a foothold on land and rooted 13 vegetation started, that changed the landscape. 14 So here you have a reference to the rooted vegetation, 15 but we don't see anything in reference to the size or composition of particles 16 surrounding rivers. So answer choice a would be incorrect because it only has one 17 of the elements that we're looking for. Not both. If we look at answer 18 choice B, it says, but at the time separating the Silurian and Devonian 19 periods, some 420 million years ago, 20 the picture found and preserve sedimentary rock changes. 21 And this case, we have kind of some reference to the sediment. 22 We don't have any reference to the rooted vegetation or h...
