Explanation for Question 20 From the Reading Section on the 2019 May Sat
Question 20 says, according to the figure water demand in Bogota in 2005 was 2 approximately what? So let's look back at the figure here. 3 Remember, we're looking for water demand in 4 2005. And again, 5 since the question starts off with the phrase, 6 according to the figure, the answer is probably going to come like very directly 7 from the figure. So if we look back here at the figure, 8 we can see that the water demand is listed on the Y axis. 9 And we can see that the years are along the X axis. 10 So remember, the year that we're looking for is 2005, 11 and we can really just trace this point back to the Y axis. 12 So if we do that, that's not really a straight line, 13 but it's good enough. So we can see that it falls right about here 14 and that the units on the Y axis are in 0.5. 15 And so since this falls between two 0.5 marks, 16 right, this would be about 14.5. 17 So halfway between 14 and 14.5 is about 14.25. 18 So let's see if that's an answer here. And it is so answer 19 choice B is the correct answer here with 14.25 cubic meters per 20 second.
