I'm sticking to A here.
"have shown" over "showed".

A, B, C are plain run-on sentences (two independent clauses joined by nothing)
D & E make no sense.

Cannot be 'B'.

It changes the meaning of the original statement.

B. Chinese scientists have shown a fossil bird found in the Yixian mountains of northern China.

While, they have demonstrated from the fossil bird found.

If fact, the answer seems to be E to me.

i think E is wordy & seem to have an issue with "100 million years ago, which..."
In E, the first which refers to "100 million years ago". Ideally it should be referring to birds feather.

My choice would be btween A & D, but i would go with D.
Birds' feathers appear to have evolved from dinosaur scales well over 100 million years ago, when the Chinese scientists found a fossil bird in the Yixian mountains of northern China

use of "when" refers to 100 million years ago...

makes sense ???

Agree that E is wordy etc, but the problem with D is - it omits the point that this fact is actually used to demontrate that the feather indeed came from scale .. blah blah...
So in a way, it changes the meaning as well...

A. Chinese scientists have shown, based on a fossil bird found in the Yixian mountains of northern China.
Run-on sentence.
B. Chinese scientists have shown a fossil bird found in the Yixian mountains of northern China.
Run-on sentence.
C. Chinese scientists showed, based on a fossil bird found in the Yixian mountains of northern China.
Run-on senctence.
D. when the Chinese scientists found a fossil bird in the Yixian mountains of northern China. it distorts the meaning of the original sentence
E. which the Chinese scientists say can be proven from a fossil bird which they found in the Yixian mountains of northern China.

Well this sentence is wordy but gramatically correct and the best choice. hence E for me.
Javed.

Really? I thought we'd circumnavigated the globe already - with the gamut of choices already covered - didn't you hear the choices were freaking wrong? Make no mistake - I kinda agree - the choices do look weird. But who said English was easy?

Do you have the OA?

buzzgaurav got it

OA is A.

A gives an understanding that Chinese scientists are based on ...

This is an 800 score question, which I know is not a good source

The question really is dubious.
Anyways, nice discussion as always.

Buzz.. I got a googly for ya; in A - weren't the chinese scientists based on a fossil bird??

Aim - where did you pick this gem up from?

In fact the other day I was skimming through the Ask Hjort section. One remarkable nugget from him goes something like this - it's TRULY hard to create a GENUINELY TOUGH question; the other varieties that are hard because of arcane logic simply can't be helped! (I couldn't quote him verbatim so the effect is only half that of the original but I'm sure you get the idea)

I know what you mean Dwivedys, but I just picked the one that had the least mistakes (though A in itself has a modifier problem).
The rest of the choices were sounding so grossly awful that I just discarded them at first glance.

But A is a run-on sentence A can't be the answere. Can somebody explain why A is the answere..?
