Explanation for Question 40 From the Reading Section on the 2017 May Sat
Question 40 says, according to the map, the population of which of the following 2 regions has the highest percentage of shared white lineages with the 3 trellis individuals. So again, 4 we're looking for the highest percentage of shared why lineages. 5 So let's take a Gander at the map so 6 we can see here that on the Y axis, 7 this is going to be difficult. This is a large map. So on the 8 Y axis, we have percent of shared Y chromosome lineages. 9 And we can see that as that percentage is increasing the colors, 10 getting darker with the darkest color, 11 representing 2.2 percentage shared. 12 So if we look at the map, we're merely looking for areas of the 13 map, right? Remember we're looking for the highest percentage. 14 So we're looking at areas of the map with the darkest color. 15 In this case, we can see that it's in like Southern and central Portugal. 16 And we can see that it's kind of in like south central 17 Turkey and also in Cyprus. 18 So let's look and see if any of those regions is an answer choice 19 for this question. Remember we have Southern central Portugal, 20 Portugal. We have Southern central Turkey and we also have Cyprus. 21 So if we look back, we can see that the only one of those, 22 thankfully, that is an answer choice here is going to be Southern Portugal. 23 And if you compare that to the three other places on the map, 24 you have British Isles with barely any color and Southern Germany and Northern Italy 25 with only a little bit of darker color. So with all that being said 26 to answer choice a is going to be the correct answer to question 40.
