Introductory sentence (B) $\rightarrow$ Specific problem in Europa (A) $\rightarrow$ Reaction to that (E) $\rightarrow$ Comparison to Earth's exception (C) $\rightarrow$ Explanation of the exception (D).
Step 3: Detailed Explanation:
B starts the topic (energy source). A applies it to Europa (no sunlight). E comments on the difficulty of A. C brings in Earth's ocean depths as a model. D describes the inhabitants of those depths mentioned in C.
