Hi @g_cirelli,

Thanks for the question! I would actually break this sentence up into two different claims. The first claim is that “The presence of such a sea is thought by scientists to be a primary factor in the early development of life.” This is just a premise. It’s used to support the conclusion, but nothing supports it. The second claim is that “there is reason to believe that there may be life on Europe.” This is the overall conclusion of the argument. We’re led to believe this from the other premises, such as the presence of a warm sea that’s been documented.

Hope this helps! Feel free to ask any other questions that you might have.

The presence of such a sea is thought by scientists to be a primary factor in the early development of life, so there is reason to believe that there may be life on Europa"
I chose E because the question stem just asks what role does the fact that warm water has been discovered play and so wouldnt the fact that there are warm waters just support "The presence of such a sea is thought by scientists to be a primary factor in the early development of life" (which is the subsidiary conlusion ) which in turn supports conclusion "so there is reason to believe that there may be life on Europa"
Please help clarify. thank you
