Question Type:
Determine the Function
Stimulus Breakdown:
Conclusion: The increased efficiency of energy transportation will probably improve industrial productivity.
Evidence: Something similar happened before -- oil and gas had increased efficiency (in the form of lower shipping costs) and industrial productivity improved.
Answer Anticipation:
They're asking us about the 2nd claim, which happens to be our Conclusion, so our prephrase is pretty easy: What role does it play? It's the Main Conclusion.
Knowing that it's the conclusion quickly eliminates C/D/E.
(How did we know it was the Main Conclusion? It has an opinion indicator, "probably", and it is supported, as indicated by the premise indicator "for")
Correct Answer:
A
Answer Choice Analysis:
(A) Yes! On a first pass just keep it, since it correctly calls our claim "a conclusion". The second half of it is accurate, since part of the Evidence (partial support) involved describing shipping costs as a function of how much material is lost in transit.
(B) Need to look closer … you COULD call a conclusion a "generalization", but this answer choice incorrectly says that the first sentence of the argument is an illustration of our conclusion. An illustration, or "example", of our conclusion would need to be a situation in which "improved energy transfer led to improved industrial productivity". The first sentence says no such thing. It doesn't even discuss industrial productivity. Although the first sentence does give some supporting context to the conclusion, we just can't call it an illustration of that claim.
(C) Our claim is a conclusion, not an assumption. Also, "assumption" will ALWAYS be a wrong answer on this question type, since by definition an assumption is "unstated".
(D) Our claim is a conclusion, not premise/evidence.
(E) Our claim is a conclusion, not premise/evidence.
Takeaway/Pattern: The four big premise indicators are F.A.B.S = "for, after all, because, since". Whenever we see "for" or "after all" indicating a premise, we know that the previous idea was a conclusion. On several tricky ID the Conclusion questions, LSAT has used this same template. Start with a fact, and make the second claim an opinion (usually indicated by an opinion indicator like "probably") that seeks to explain that first fact or draw some implication from it.
