The topic at hand is why Mars atmosphere lacks water. The reason for that is given in 4 and 2. Sentence 1 also talks about the water being lost, but the word ‘was lost’, suggest that there is a sentence before that talks about the why water in the land is missing. Such a sentence does not exist. Hence we can determine that sentence 1 is the odd one out.
