Explanation for Question 51 From the Reading Section on the Official Sat Practice Test 6
Question 51 says, according to figure one in 2017, 2 the cost of which of the following fuels is projected to be the closest 3 to the 2009. Us average electricity costs shown in figure two. 4 So answering this question is going to take two steps. 5 The first one is to determine the average electricity costs in 6 2009 from figure two. And then the second step will be to compare that 7 to the prices of fuels in figure one. 8 So let's look back here. 9 If we start by looking at figure two, 10 we can quickly identify, it gives us an arrow with a very nice presentation 11 there that the 2009 U S average electricity costs is $120 12 per megawatt hour. So the cost, 13 again, that we're looking for is $120. 14 So that was step one that I talked about earlier. 15 So step two is going to be comparing that to the prices of fuels 16 in figure one. 17 So if we scroll up again here, 18 we can draw a little bit of a line at 120. 19 So this line here is probably well is at 125. 20 So we can assume that align at 120 would probably 21 be right about there. So we can quickly see that 22 the closest fuel to that is going to be advanced nuclear on 23 the kind of under $120 side. 24 And you can see that over it is going to be the solar photovoltaic, 25 right? So you have it here or here, 26 but we can clearly see from this, 27 that just in general terms of closeness, 28 that the advanced nuclear is going to be the closest to that $120 mark. 29 So let's look back at the answer choices and see if that is in 30 fact given to us. 31 So we can see that advanced nuclear is given to 32 us as answer choice D so with all that being said, 33 answer choice D would be the correct answer to question 51.
