Explanation for Question 31 From the Reading Section on the Official Sat Practice Test 10
Question 31 says according to the passage, 2 G L differed from allowance, other tests, 3 subject in terms of what? So it would be go back into the passage 4 and look at where the author is comparing GL and 5 allowance. Other test subjects. We can find the answer to this question. 6 So we find it in the last paragraph where it says that they're 7 using MRIs to examine which areas of the brain light up. 8 And then it goes on to tell us that in normal subjects, 9 both the somatosensory and insular courtesies were activated, 10 but only the insular cortex was active when researchers brushed G L 11 arm. So the difference between normal test subjects in GL 12 is the number and the kind of cortex that lights up. 13 So in normal, you have some medicine and insular courtesy, 14 so two, and then in GL you only have the insular cortex. 15 So one that light up on the MRI. 16 So if we go back and look at the answer choices in question 31, 17 it says that answer choice a says, 18 the number of the cortisol is activated in the brain during gentle brushing is 19 how GL differs, which is exactly what we just talked about. 20 Right? So GL only has one quarter cortex light up while normal subjects have 21 two. So that's a good answer here. 22 B says the physical dimensions of this amount of sensory cortex is where they 23 differ. So that paragraph doesn't say anything about the physical dimensions 24 of this amount of sensory cortex, whether it's bigger or smaller, 25 more a morphous, what have...
