   The final ingredient here is a great fit, so this survives the first pass. But the opening ingredient sounds more like the 2nd paragraph than like the beginning of the passage. We don't get into the "complications / difficulty" of classifying lichens until Paragraph 2.

   definition of lichens; discussion of new discoveries concerning lichens’ evolutionary history; application of these findings in support

   The final paragraph applies these new findings to an evolutionary theory, but its doesn't support the theory. "It provides evidence to help overturn the long-standing evolutionary assumption".

   definition of lichens; discussion of the difficulty in classifying their fungal components; resolution of this difficulty and implications

   Why this is right

   The last ingredient checks out (implications of research), so we read the rest. Do we start by defining lichens? Yes, that's our first sentence. Do we proceed to discuss the difficulty in classifying their fungal components? Yes, the first half of P2 does this. Do we present a resolution of this difficulty? Yes, the second half of P1 and P2 do this. Do we end with implication of the research? Yes, P3 does this. This answer is a little annoying because it skips over most of the 1st paragraph without mention, but it still ends up being the answer whose descriptions all match the passage and whose start-to-finish progression best captures the beginning-middle-end of the passage.

   Skill tested: Organization · how this choice captures the passage's function is the move to repeat next time.

   discussion of the symbiotic relationship that constitutes lichens; discussion of how new research can distinguish parasitic from symbiotic

   The last ingredient (implications) looks good, so we check out the rest. Did the passage begin by discussing the symbiosis that constitutes lichens? Yes, 1st sentence does that. Do we then discuss how new research can distinguish parasitic from symbiotic fungi? No. We discuss how new research can disentangle the fungus from the algae, so that we can look at the specific DNA of the fungus.

   explanation of the symbiotic nature of lichens; discussion of the problems this poses for genetic researchers; delineation of the implications these

   Bad Last Ingredient Incomplete: lacks new study's findings The last ingredient looks good at a glance (implications for evolutionary theory), but the last paragraph is saying "here are the implications of this new stuff we found out about the fungus family tree". This answer is saying the last paragraph is discussing "the implication of problems posed by the symbiotic nature of lichens". The 1st ingredient matches the 1st sentence. The 2nd ingredient matches the first half of P2. But nowhere in this answer is the second half of P1 and P2, where we announce that a new study has transcended these problems and discovered some of the info we had been seeking! And then the 3rd ingredient should be talking about the implications of that info we discovered, not implications of problems.
