   Without the existence of other life forms, human life would never have

   This is not a rule that can prove "same origin", so it's functionally useless to us. We need some proving-mechanism for "same origin", like if xyz is true ? same origin On Sufficient Assumption, the correct answer combines with some piece(s) of existing evidence and allows us to derive the conclusion. We can't derive "same origin" if neither the evidence nor the answer choice use that term.

   Any two living things made of the same basic kinds of matter have

   Why this is right

   Can it really be this easy? They're only giving us one answer that has the Conclusion's wording in it? Yes, it can! That's the joy of Sufficient Assumption. The correct answer combines with stuff we know from the evidence to allow us to derive the conclusion. If we're concluding something about "Z", then either the premise or the correct answer needs to mention Z. So if the premises never mentioned Z, then the correct answer absolutely has to. This gives us a proving-mechanism for "same origin": If two living things are then they have made of the same basic ? the same origin kinds of matter We know that human life is made of the same basic kinds of matter as all other known life (since all known living things are made of the same basic kinds of matter). According to this rule, if two things are made of the same basic matter, then they have the same origin. So this proves that human life has the same origin as all other life.

   Skill tested: Sufficient Assumption · how this choice captures the argument's function is the move to repeat next time.
