potential answers all right about a bunch of dates right

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

- 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

we can find some relationship between sea ice cover and

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
