Based on the chart, which of the following statements is true?
- 00:25
And here are the potential answers...
- 00:30
We are being asked to just read a graph and deal with a bunch of random questions which…
- 00:34
we really have to cover one by one.
- 00:36
So… as Nike suggests… let’s just do it.
- 00:40
Potential answer A:
- 00:42
Amount of time on homework: 13%
- 00:44
Amount of time on free time: 17%
- 00:47
Total 30%
- 00:49
Amount of time sleeping: 33%
- 00:52
So A is false – this girl must be beautiful – she certainly gets enough beauty sleep.
- 00:56
OK, try B.
- 00:58
Homework: 13%
- 00:59
Free time: 17%. Total 30%
- 01:02
Versus time spent at school: 25%. Clearly not equal.
- 01:07
OK, C.
- 01:08
Free time at 17% plus sports at 8% plus eating at 4% totals 29% - nope – she slept 33%
- 01:15
of the time so C is false as well.
- 01:18
D had better be true or we’re in bad shape.
- 01:22
D.
- 01:23
Homework: 13%, free time 17% is – yes – less than the 33% she spent sleeping.
- 01:29
So thank goodness… D is true.
- 01:31
As in… “Denial.”
