Explanation for Question 27 From the Reading Section on the Official Sat Practice Test 10
Question 27 says which choice provides the best evidence for the answer to the 2 previous question. So it's paired with 26, 3 which tells us that the fact that gentle pressure is sends not only by 4 fast fibers, but also by slow fibers is best supported by the findings of 5 allowed since 1993 experiments. So answer choice C is what we're trying 6 to prove here. If we go look at the lines of evidence that they 7 give us in 27, we can see which one best supports 8 that. So if we look at answer choice, 9 a lines 22 through 26, it says using a technique called micron urography 10 in which a fine filament is inserted into a single nerve to capture its 11 electrical impulses. But scientists were able to measure how quickly or slowly the nerves 12 fired. So answer choice aid. 13 Doesn't give us any information about how pressure is sensed by the nerves. 14 It's merely explaining a way to measure how nerves 15 fires. So it doesn't give us that necessary element of pressure and answer choice 16 a. So that's why that's incorrect. If we look at answer choice B, 17 it says they showed that soft stroking prompted two different signals, 18 one immediate and one delayed. So in this case, 19 this soft stroking can be assumed to be pressure or 20 can be synonymous with pressure. And it is, 21 it goes on to tell us how those sensations are received or interpreted. 22 So be it could be a good answer choice here. If we look at 23 answer choice C, it says the delay allows and explains means that ...
