QUESTION TYPE: Principle – Strengthen
CONCLUSION: The author should collaborate with another writer on their next book (any other writer).
REASONING: The author’s recent book sold well, and it was produced as a result of collaboration.
ANALYSIS: This argument doesn’t prove much. We don’t even know if the collaborated-on book sold better or worse than the author’s other books. It sold well, but other books could have sold even better.
Further, there are other reasons the book could have sold well, apart from the collaboration. And collaboration with a different author might not produce the same results.
___________
- The argument’s conclusion doesn’t specify that collaboration should be with the same writer. This is too narrow.
- The conclusion is that the next book will sell well. This answer choice only tells us that collaboration is a necessary condition for good sales, not a sufficient condition.
- CORRECT. This rephrases the conclusion in general terms, and certainly supports it.
- Because this doesn’t offer a comparison to writers who do collaborate, this doesn’t help.
- We don’t know if this guy or his collaborator are good writers.
