Question

Statement: NASA has logged another extraterrestrial first on its latest mission to Mars: converting carbon dioxide from the Martian atmosphere into pure, breathable oxygen. The instrument that was used for the purpose works through electrolysis, which uses extreme heat to separate oxygen atoms from molecules of carbon dioxide, which accounts for about 95% of the atmosphere on Mars.
Assumptions:
I. There is no natural oxygen in Mars’ atmosphere.
II. Mars can now successfully support terrestrial life.

In each question a statement is given, followed by two assumptions, numbered I and
II. An assumption is supposed or taken for granted. You have to consider the statement and assumptions and decide which of the assumptions is implicit in the statement.
A Only I is implicit
B Only II is implicit
C Both I and II are implicit
D Neither I nor II is implicit
E Either I or II is implicit
