Which of the following most logically completes the argument?

Bacteria might have developed on Mars early in its history. Theoretically, such Bacteria could have been to Earth by a meteorite. But, strains of bacteria from different planets would probably have substantial differences in protein structure that would persist over time. No two bacterial strains on Earth are sufficiently different planets. So if bacteria that originated on Mars were brought to Earth by meteorite either such bacteria died out or_____________.

(A) other strains of bacteria were carried from Earth to Mars early in the history of Mars.

(B) all bacteria now on Earth are descended from transported Martian bacteria.

(C) meteorites are not the only means by which bacteria could have been transported between Mars and Earth.

(D) the environment of Mars was more hostile for bacteria than was that of earth at the same time.

(E) any martian bacteria that did arrive on earth did so only after all bacteria had disappeared from Mars.

But the fact is that structure of protein doesn't appear from two different planets...

So we have 2 possibilities -

1. All the bacteria from the orange planet (Mars) died and we now have the bacteria from the green planet { Expressly stated in the stimulus in blue }
2. There are no bacteria from the Green Planet and all bacteria found on earth are descendents of the bacteria from Mars..


Option (B) is clearly our assumption point (2)

What B is basically stating is that we can't tell the difference because if the bacteria didn't die we would be able to notice it UNLESS it all came from Mars- in which case how could we know the difference?

The answer is B


The reasoning given for the argument is that bacteria that originated in mars and brought to earth by meteorite must have difference and the differences will persist .
Bacteria from a given planet are similar thus if the bacteria that originated in mars and brought to earth is not different from the bacteria found on earth then the bacteria from mars must have died out .


If the bacteria from mars is living then it must show difference with bacteria from earth .

If there is no difference then all bacteria on earth are from Mars .

NandishSS, is this an official question or an adaptation of this official question? If it is an official question, please transcribe it EXACTLY as it appears in the source. If it is an adaptation, the source should be "Other" or "Self-made". Please refer to the Rules to post on the Verbal Forum before submitting a post.

Also, please try to make your questions a bit more specific or, at the very least, to let us know your thoughts so far. That way, you are more likely to get a valuable and timely response.

Thanks!
