[Video] Q51: Which choice provides the best evidence for the answer to the previous question?

Explanation for Question 51 From the Reading Section on the Official Sat Practice Test 8

Okay, so we're going to do number 50 and 51 together since they're buy 2 one, get one free questions. Um, 3 if you says based on the passage, what potential criticism might be made of 4 vocals testing of Hodel and see ever's model. 5 Remember his model, his testing of the model did not include anything about calcium. 6 Remember he only looked at electricity, he did not touch calcium. 7 So I'm already thinking that's probably what it's going to be. 8 Right? Like the fact that he doesn't even test for calcium is an issue 9 because that was at the main point of the model by holding NC Evers. 10 Um, so let's see if that's talked about, 11 it says that the evidence will be found somewhere in the later half of 12 the passage between 66 and 77. So let's just read those lines. 13 So it starts here, um, 14 the first semester, if that is indeed electricity, 15 that causes the unified to have to close to test the model. 16 They wake up verify electrodes and, um, 17 applied and, uh, current to the libs of the trap. 18 This made the trap close without any direct touch to the trigger hairs while 19 it didn't measure calcium was the current likely lead to increases. 20 Okay. So why is 74, 73 I'm already like, 21 wow, that probably is the answer because line 73 touches on the fact that 22 they didn't even look at calcium levels when they modified this experiment by altering 23 the amount of electric current, um, bulk could determine the exact electrical charge needed 24 bubble, blah, blah, b...
