Let’s see if you can shmoop what we’re layin' down...

00:07

In a math class, the teacher gives the students a pop quiz every week.

00:11

We know… she must have been commissioned by the devil.

00:17

The number of problems on each quiz is always the same.

00:20

If each problem on the quiz is always worth five points and takes an average of three minutes to finish,

00:26

what other information is needed to find the number of problems on each weekly quiz?

00:31

And here are the potential answers...

00:36

OK, so this question is all about just reading and deducing the broader, factual story here…Sherlock.

00:42

By glancing at options C and D, we can see that we really just need to test the validity

00:46

of A and B to get our answer…

00:48

A suggests that we’d need the total number of points on each weekly quiz.

00:52

That makes sense. Say we know there are 50 points possible. We already know that each

00:57

problem is worth 5… 50 divided by 5 is 10, and we’d know there are just 10 problems.

01:03

A gets through to the lightning round.

01:07

What about B?

01:08

Here, it’s suggested that all we’d need is the amount of time allowed to complete the quiz.

01:13

Hey, what do you know… that works, too. If we’re told the class has an hour, we

01:17

can take 60 minutes divided by 3 minutes per problem to get… 20 problems.

01:22

B is also through to the lightning round.

01:26

Unfortunately for our two ultra-competitive contestants… there is no single winner here.

01:31

Both A and B are correct, so we’ve got ourselves a tie.

01:34

And we’ll want to go with choice C for our final answer.

01:37

As in C, “Class… NOT dismissed…”
