Looks like we’re being asked to take into account the results of the study and see what

00:41

we can predict with that information. Classic science move.

00:45

Knowing what we know about the waggle dance—

00:47

namely, that it produces a smelly chemical to communicate information about food—

00:52

which of the potential answers is a good prediction?

00:55

Let’s start at the bottom, a very good place to start…

00:58

Option D predicts that the chemicals produced by the waggle dance should cause the bees to mate.

01:04

Hope not. With all that dancing and making out, nobody would ever get anything done.

01:09

More to the point, this prediction isn’t based on anything we’ve learned

01:12

about the waggle dance. So long, D.

01:14

Option C predicts that the waggle dance should cause the bees to mate.

01:19

Again, the passage says the purpose of the waggle dance has to do with

01:22

communicating information about food.

01:25

It’s not C.

01:26

C’mon guys, let’s keep it classy.

01:28

Option B predicts that all bees should produce the waggle dance chemicals.

01:32

Nope. Whether or not all bees are capable

01:35

of producing the chemicals isn’t a prediction based on what we’ve learned.

01:39

Option A predicts that if air with the chemical is introduced into the hive,

01:44

it should be the same as getting the signal from the waggle dance.

01:48

This one certainly takes into account what we learned from the experiment,

01:51

which is more than we can say for the other options. A it is!

01:55

Interesting thing about bees—if a beekeeper ever shows you a hive,

01:59

there’ll probably be a small dot of paint on the queen’s back to help keep track of her.

02:03

Beekeepers didn’t invent that; it was originally invented to keep tabs on Queen Victoria.
