Explanation for Question 23 From the Reading Section on the Official Sat Practice Test 10
Question 23 says which choice provides the best answer for the answer, 2 the best evidence for the answer to the previous question. 3 So it's paired with question 22, which says that based on 4 the passage textbook authors in the early 1990s, 5 would most likely have expected which condition to result from blocking a fast fibers. 6 And the correct answer to that was answer choice D that the ability to 7 perceive vibrations would be impaired. So if we look at the passage, 8 we can examine these lines of evidence that they give us for answer choices 9 in 23 and see which one best supports that. 10 So if you look at answer choice a lines, one through four, 11 it says, and the early 1990s textbooks acknowledged that humans had slow conducting nerves, 12 but asserted that those nerves only responded to two types of stimuli, 13 pain and temperature. So if we look back at question 22, 14 question 22 is asking us about fast fibers. 15 So any answer choice that gives us evidence that has to do with slow 16 fibers, but not fast fibers is going to be incorrect just as a does. 17 Um, and telling us about the 18 responses that slow nerves that Sloan or fibers 19 respond to. So is incorrect for that reason. 20 If you look at answer choice B it's lines, five through seven or four 21 through seven, it says sensations of pressure and vibration were believed to travel only 22 along myelinated, fast signaling nerve fibers, 23 which also give information about location. 24 So this is giving us t...
