<p>On the second edition, test1 section 9(reading section, page 426), could anyone provide explanations for questions 11, 16--I have looked at CB online explanation but still doesn't make much sense to me.</p>
<p>btw, I put C for 11 and D for 16.
Thank you!</p>
<p>11 is A because profligacy means the guy spends toomuch money, thus wastes his time in undignified pursuits. </p>
<p>16 is B because she thinks that her uncle is predicting a bleak future of an unmarried life.</p>
<p>^lol</p>
<p>11)
let ‘a’ represent the area of the small rectangle and ‘A’ represent the total area of full rectangle.</p>
<p>2a = area of next rectangle
Each rectangle has twice the area of the last so,
2(2a) = 4a = area of next rectangle
2(4a) = 8a = area of next rectangle
16a = next rectange
32a = next rectangle
(6 different areas, a, 2a, 4a, 8a, 16a, 32a)
The total rectangle is made up of rectangles with areas of a, 2a, 4a, 8a, 16a, 32a. There’s two rectangles with area of ‘a’ though as shown, so the total area ‘A’ is</p>
<p>A = a + a + 2a + 4a + 8a + 16a + 32a
A = 64a
A/64 = a<br>
So, The area of the shaded rectangle has an area 1/64 of the total (B)</p>
<p>16) you got the right answer.</p>
<p>Huh? He said it’s a reading section.</p>
<p>@cjgone, I think you might be looking at a wrong test or the book (mine is second edition)</p>
<p>@garfieldliker, I still can’t understand why the answer is A, I can’t make the connection between him spending money to undignified pursuits.</p>
<p>Haha, I fail. I have 1rst edition, and page 426 is section 9 has questions 11 and 16 for math. :P</p>
<p>
Lol, I read your answers completely out of context.</p>
