[Video] Q25: Which choice provides the best evidence for the answer to the previous question?

Explanation for Question 25 From the Reading Section on the Official Sat Practice Test 7

Question 25 asks, which choice provides the best evidence for the answer to the 2 previous question. So we determined in an earlier video that the correct answer to 3 question 24 was going to be answered choice D that the recent usher word 4 used Northern bald Ibises as a subject of his study was because they were 5 easily accessible for Usherwood and his team to track and observe. 6 So let's look at the lines of evidence given to us as answer choices 7 and question 25 and see which one best supports that idea. 8 So we're looking for the idea of the 9 Ibis as being easily accessible. 10 So we'll start with answer choice a lines three through seven, 11 say a study of our, a new study of IVUS is finds that these 12 big winged birds carefully position their wingtips and sink they're flapping, 13 presumably to catch the proceeding birds, 14 updraft and save energy during flight. 15 So answer choice a doesn't really contain any reference to Usherwood or his team. 16 And there's no really idea here that the Ibises are easily accessible for scientists 17 in general. So answer choice a would be insufficient to support that answer. 18 If you look at B, it says squadrons of planes can save fuel by 19 flying in a V formation and many scientists suspect that migrating birds do the 20 same. So this sentence is more centered around those, 21 uh, squadrons of planes, right? And again, 22 there's no reference to the accessibility of irises. 23 So B would be incorrect if you look at C, 24 it ...
