could anyone help me Organic molecules are sometimes found within meteorites that crash into Earth. Which conditions on meteorites in space are similar to those that likely prevailed on Earth early in its history? A. no oxygen B. very cold temperatures C. absence of liquid water D. high levels of carbon dioxide E. presence of inorganic molecules F. high levels of ultraviolet radiation
Is more than one answer possible for this question?
yes
B, D, and F C, D, and E A, E, and F A, B, and C
So what choices can you eliminate?

this is the way the questions is
OK, do you know whether A is true?
no
for me the answer is C, D, and E
A is true. there is no oxygen in space, and there was no free oxygen in the Earth's atmosphere or water.
B is true for space, but not for early Earth - Earth started out hot and took a while to cool after it's formation, until it reached a temperature where water could condense and form oceans.
So A is true, and B is false. There is only one answer choice left that includes A and does not include B.
