Although the first humans came to Australia 56,000 years ago and undoubtedly brought new diseases with them, human-borne diseases probably did not cause the mass extinction of large land animals and birds that took place over the following I0,000 years. After all, more than 55 different species disappeared at about the same time, and no one disease, however virulent, could be fatal to animals across that many different species

Which one of the following arguments exhibits flawed reasoning that is most parallel to that in the argument above?
(A) Even though high-interest rates can lead to
an economic downturn, high-interest rates probably did not cause the current economic downturn. It is true that rates have been on the rise, but high interest rates are not always economically harmful.
(B) Even though I can fix some things and you can fix some things, the two of us will be unable to repair our apartment without outside help. The apartment has both a broken window and a broken bedroom door, and neither of us is able to fix both doors and windows.
(C) Even though Lena, Jen, and Mark would like to go out to dinner together after the movie tonight, they will probably go straight home after the show. Of the five restaurants that are in the immediate vicinity of the theater, there is not a single one that all three of them like.
(D) Even though this painting is highly regarded by critics, it cannot legitimately be deemed great art. Most art that was produced in the last hundred years is not great art, and this painting, beautiful though it is, was probably painted only 40 years ago.
(E) Even though the influenza vaccine does not always prevent influenza, it sometimes reduces the severity of its symptoms. Therefore it is incorrect to say that some people who receive the vaccine derive no benefit from it.
LSAT
The argument rests on a tiny thing you need to notice.
First humans brought new diseases.
But no one disease can be fatal to 55 species so together, the new disease probably did not cause the mass extinction.
Notice the distinction between disease and diseases. Human brought new diseases but since no one disease could have killed all these species, the diseases together would not have killed all.
(B) Even though I can fix some things and you can fix some things, the two of us will be unable to repair our apartment without outside help. The apartment has both a broken window and a broken bedroom door, and neither of us is able to fix both doors and windows.
Option (B) makes the same mistake - since neither one of us alone can repair both the things, together we cannot repair both the things.
