We are comparing the likeness between two items, so 'like' is appropriate
I'll take B, as we're comparing the "increased speed of earth's rotation" to "increase speed of figure skater"

B for me.

a tough one I just wanna mention sth about its meaning first.
The act of drawing in two arms to increase one's spead is effective only when he/she is in rotating motion----> the correct sentence must contain " spinning" to describe such motion.
As I notice there's a comma in the original sentence, IMO, " just as" after a comma is ok but not for "like" ( anyway, I checked it out in my SC book).
I would go for E after all.

'just as' is required because we are comparing dissimilar items;
E fits better

E for me

I think when we give an example, we should use "as" instead of "like"...

E is more concise..

E is wrong because "just as" makes too similiar of a comparison. If we were comparing the rotation of the earth to that of Mars (two planets with nearly identical rotation speeds) then "just as" would be acceptable. But here, a figure skaters centripetal motion is only somewhat "like" the earths in a very fundamental way.

C over B for the active voice construction.

I was confused about "just as" at first ....it compares two very alike objects ....but ...uhm ....still keep my original answer anyway

To take this SC analysis one step further, how can we automatically assume that the figure skater is a woman and therefore use the pronoun "her?"

Missed that

Still think B or C are the best of the lot. How can we possibly make such a similiar comparison between a spinning skater and rotating planet?

In both C and E, the skater causes the faster spin, whereas in B the faster rotation/spin are resulting actions.

I waiver between B and C, but definately not E.

Matt got a point when he pointed out that both things are not alike at all. So normally D and E should not be correct.
However I feel E is the OA, I feel other sentences are weird.

I think E is correct.

Like is for similar items, so A,B,C are ruled out.

D compares build up of ice and water with spinning skater 'WHO'

X) the buildup ... speed up the rotation as a skater increases speed by...
Y) the buildup ... speed up the roration like a skater ...

X seems fine to me.

However, from Y, I don't get what are the two things being compared.
buildup and skater? rotation and skater?

What`s the point in posting such a controversial SC without providing its explanation? We need to know why E is right and why the others are wrong in order to learn from this example.

(B) like the increased speed of a figure skater when her arms are drawn in
(C) like a figure skater who increases speed while spinning with her arms drawn in
(D) just as a spinning figure skater who increases speed by drawing in her arms
(E) just as a spinning figure skater increases speed by drawing in her arms

Matt, even if you didn't agree with E, you should still pick it cause it contains fewer errors.
B can't be correct answer coz it somehow changes the meaning ....You should know that the drawing in one's arms to increase speed applies only to spinning motion. B doesn't mention a spinning motion,right?!
C somehow shifts the meaning as well. No one says that one can increase speed ( in general) by spinning and drawing in his/her arms . C would be correct if it were like this " like a figure skater who increases spinning speed by drawing in her arms"
Hope you catch the point

Originally C, then changing to E...E also compares the action of the skater and not "her"...just as a spinning figure skater increases blah blah...

Good one.
