Explanation for Question 30 From the Reading Section on the Official Sat Practice Test 7

Question 30 asks the author uses the phrase, 2 aerodynamics sweet spot in line 63, 3 most likely to do what? So let's look back in the passage at the 4 sentence that this phrase is contained and get some context and then see if 5 that will help us answer this question. So looking at the sentence, 6 it says, scientists do not know how the birds find that aerodynamic sweet spot, 7 but they suspect that the animals aligned themselves either by sight or by sensing 8 air currents through their feathers. 9 So if you've read on a little bit, 10 it says, alternatively, they may move around until they find the location with the 11 least resistance. So you can see that they're kind of paralleling this aerodynamic 12 sweet spot with the location, 13 with the least resistance. And the way that you can interpret that from these 14 lines is that they're talking about, they don't know how the birds find this 15 aerodynamic sweet spot, but a way that they might do that is that they 16 move around until they find that location. 17 Right? Ideally these birds are looking to be in the aerodynamics sweet spot. 18 They're also looking to be in the location with the least resistance. 19 So you can kind of equate those two things to each other. 20 So let's look and see in the answer choices, 21 if any of them outline that idea. 22 So answer choice a says to describe how the proper structural design, 23 the proper structural design of an airplane helps to save fuel answer choice is 24 going to be inc...
