Hi
I am not convinced with OA. Pl help where my thinking is incorrect.
Argument Says:
The greatest chance for the existence of extraterrestrial life is on a planet beyond our solar system. The Milky Way galaxy alone contains 100 billion other suns, many of which could be accompanied by planets similar enough to Earth to make them suitable abodes of life.
So, Conclusion is "The greatest chance for the existence of extraterrestrial life is on a planet
beyond our solar system." I think main phrase to focus is
beyond our solar system.
Now Option B Says "Life cannot exist on other planets in our solar system." If We negate this : Life CAN exist on other planets in our solar system, argument breaks. We do not require to go beyond our solar system
Whereas E says : It is likely that life on another planet would require conditions similar to those on Earth. Negating this option: It is NOT likely that life on another planet would require conditions similar to those on Earth. So Life can exist anywhere in out Solar System or beyond our Solar System Hence Argument does not breaks apart.
Please help to correct my reasoning.
