I am unable to understand what option D even means? Can someone pls explain?

Thank you for the question Bixy34,

D was a pretty tricky answer but in its trickiness it ended up requiring an additional assumption which the question writer missed and thus made it a great tricky question but with a flawed assumption. I have updated and changed the answer choices to make the question more straightforward, though I feel this will still be a fairly tricky question as it is "undermine" and on the harder side.

Hi everyone,

It is unclear why B is "irrelevant". B implies that fullerenes' origin can be extraterrestrial. If so, studying them tells us nothing about Earth’s formation conditions → that undermines the argument.

To me both B and D can undermine the argument and it is unclear to me how we select the answer choice that undermines "most seriously". Any ideas on that?

Hi. Thank you for the question. I would probably say that a piece of evidence can either strengthen the argument, undermine the argument or have no impact on the argument.

Thus all irrelevant comments would have no impact on the argument which would be neither undermine nor strengthen.

Hi, and thanks so much for your answer!
I just wanted to add that I feel option B also weakens the argument, so it’s not entirely clear to me how we’re supposed to choose between B and D. Honestly, I can see valid points for both. The fact that the answers are pretty evenly split (29% for B and 35% for D) kind of reinforces that confusion for me.

Thank you for the comment.

Re-reading it and thinking for a long time, I agree that it is a possible weakener as well. Thank you for bringing it up.

On a side note, the whole the spacecraft irks me. Why meteorite needs to be colliding with a spacecraft is beyond me or how some of the remains of a meteorite would have been recovered. That just seems un un-plausible condition to me so I am probably biased this way. I will update it to make meteorite crashed to the earth type of thing...

So I am going to have to seriously update the answer choices. And as a thank you for your help pointing it out and sticking to your guns, I am providing you with a 2-week extension to your tests.
Thank you,
BB
