Thank you We sneak and here's your shmoop du jour

00:05

brought to you by sea ice Fortunately you don't need

00:08

to bother learning what that is because well it probably

00:11

won't be a thing in twenty years way We're just

00:14

getting chill Check out this passage and felling after if

00:17

only marivan in the new polar bear study scientists study

00:20

confirmed the hybridization entry of government you nevada in norway

00:25

and their chart hands death Okay it can reasonably be

00:29

inferred from the passage in graphic that polar bear population

00:32

increased during which of the following periods and hear the

00:35

potential answers all right about a bunch of dates right

00:37

there Approximate dates Ah yes this would be referring to

00:41

the great polar bear migration from europe When the famed

00:44

polar bear explorer ferdinand mammalian happened upon the north pole

00:49

and claimed it in the name of oh they didn't

00:52

migrate there from anywhere else Then how is there any

00:56

increase in pop You all right Well we're with you

00:59

Okay This is actually a tricky one We're asked refer

01:02

to both the passage and the graphic to determine what

01:05

time period featured the greatest spike in polar bear population

01:09

Well why can't we just look at the graphic Because

01:11

this graph isn't measuring polar bear population it's measuring sea

01:15

ice cover Uh sneaky So what we'll need to do

01:18

then is look at the passage first and see if

01:20

we can find some relationship between sea ice cover and

01:23

polar bear population Hey there hold the elevator Check out

01:27

the tail end of paragraph two Scientists also found that

01:31

polar bear populations expanded and brown bear populations contracted in

01:34

periods with mohr ice Well that's what We wanted to

01:37

know more ice equals more polar bears Okay now we

01:42

can take a look at the graphics well option They

01:44

would have us believe that population soared from eighty three

01:47

to eighty six Yet if we take a look at

01:49

the graph and find those points well now looks like

01:51

the sea ice cover goes down over that period of

01:54

time Meaning so does the number of polar bears option

01:56

b eighty eight to ninety Same deal an option d

01:59

o c so seven Yikes Hope these guys are good

02:02

swimmers Option c the period of time from ninety four

02:05

ninety five is the only one where the line seems

02:08

To be trending upward on the graphic hitting its high

02:10

point in ninety five with more sea ice cover we

02:14

can assume there were also more polar bears per the

02:16

passage so we can confidently select option c is our

02:20

final answer And hey there mr polar bear Sorry about

02:22

teasing you early about your melting homeland We realized Now 00:02:25.95 --> [endTime] that joke was pretty yet cold Oh
