Explanation for Question 26 From the Reading Section on the Official Sat Practice Test 7
Question 26 asks what is the most likely reason the author includes the 30 2 centimeter measurement in line 30. 3 So let's look at what this 30 centimeter measurement is made in reference to. 4 And then we can determine the correct answer for this question. 5 So it says the, has GPS determined each bird's flight position to within 30 6 centimeters and an accelerometer showed the timing of the wing flaps. 7 So just a reminder, what we're looking at here is this 30 centimeter measurement. 8 And so what they're saying here is that the technology tracks the birds to 9 within 30 centimeters of their actual position. 10 So this is more of just like an evaluation of the accuracy of this 11 GPS technology. It can track the birds to within 30 centimeters of their actual 12 position. So let's look at the answer choices here and see if any of 13 them address accuracy. So it says to demonstrate the accuracy with which 14 the data loggers collected the data. 15 So that's pretty right on with what we were just saying. 16 Answer choice B says to present recorded data about how far and IVUS flies 17 between successive wing flaps. That's going to be incorrect again, 18 that 30 centimeters was made in reference to where 19 the bird is within a certain measurement. So not how far they're flying CSUs 20 to provide the wingspan length of a juvenile Ibis again, 21 incorrect. And then if we look at D it says to show how far 22 behind the microlight plane, each IBUs flew again, 23 incorrect. So answer choice a is going to be the correct answer for question 24 26, because it appropriately indicates that that 30 centimeters is a degree of 25 accuracy measurement.
