Here's your shmoop du jour, brought to you by plant biology. You'd better be-leaf it.

Here's a passage about plant patterning and two viewpoints given by scientists. It's a

00:13

little bit of reading, "soil" wait over here.

00:25

According to Scientist 1, why do plant patterns come in waves or periods?

00:30

And here are the potential answers:

00:35

This question is asking us to read through Scientist 1's passage. Take a break, Scientist 2.

00:40

We're specifically looking for the reason Scientist 1 believes plant patterns come in waves.

00:46

Scientist 1 said a mouthful, but what it seems to boil down to is that patterning is caused

00:50

by auxin. Option A says that, too. There's a pretty good chance this is our answer, but

00:55

let's examine all options before calling it a day.

00:58

B suggests stress would be the cause of patterns appearing in waves. Scientist 1 didn't mention

01:04

stress at all. In fact, stress is the furthest thing from his mind right now.

01:08

Option C says natural disorder is responsible. Scientist 1 didn't say anything of the sort,

01:14

so nope. How about D? PIN1 clustering? We've already

01:18

looked at that viewpoint enough times that you can probably guess the answer here. Scientist

01:22

1 didn't say a word about PIN1 clustering.

01:23

In fact, the nice thing about those capital letters in PIN1 is it makes it really easy

01:28

to skim back over Scientist 1's viewpoint and look for them. So let's triple-check.

01:32

Nnnnnnnnope, not seeing it. There we have it, option A!
