Transcript

00:03

Here’s your Shmoop du jour, brought to you by royal jelly.

00:07

Whether it’s on toast, bagels, crackers, or candy crush you’ll eat like a queen.

00:14

Here’s a passage about honey bee communication.

00:17

It’s all the buzz right now.

00:29

“Which of the following is NOT a chemical represented in a peak in Figure A?”

00:35

And here are the potential answers...

00:42

Figure A, being the top half of the chart we just saw, has 4 main peaks.

00:47

The end of the passage describes what each of those peaks represents,

00:51

so it should just be a simple matter of matching them.

00:55

So let's go.

00:56

Option A: Z-9-tricosene <<try-co-zeen>>. Try-co-say that 5 times fast.

01:01

Looking back at our list in the passage, it’s definitely in there. Sorry, A.

01:06

Option B: Tricosane. Try-co-say… okay, sorry.

01:12

Looks like tricosane is in the passage, too.

01:15

So long, B.

01:17

Option C: Z-9-pentacosene <<pen-tuh-CO-zeen>>.

01:20

Yeah, that’s there too. That just leaves…

01:23

<<interrupted by screeching hawk>> Oh goodness. I hope he’s okay.

01:26

Option D: Pentatricosane <<pen-tuh-try-CO-sane>>.

01:29

In the passage we see the similar-sounding pentacosane <<pen-tuh-CO-sane>>.

01:33

Not the same, though.

01:34

That means our answer is D. <<distant hawk screech>>

01:38

Aaaand it’s time to get out of here.
