Journalist: It is unethical for journalists to lie—to say something untrue with the purpose of deceiving the listener—to get a story.
Implicit Conclusion
It isn't unethical for a journalist to withhold relevant information in interviews, in order to elicit new info.
Evidence
The argument that fails to recognize the distinction between failing to prevent a false belief and actively encouraging one.
Lying is unethical because it actively encourages a false belief.
Evaluate
We get an attribution, "Some argue that X", and then a pivot (but, yet, however), so we know our author is rebutting a point of view. Thus, even if she doesn't spell out her conclusion, we can assume it to be "this view is wrong".
Our job is to characterize the type of evidence or reasoning pattern. The author calls out a distinction that's being overlooked. The argument she's rebutting tries to argue by analogy.
Our author is pointing out a meaningful difference between the two cases that makes them disanalogous.
Goal
Look for any answer whose language we can match up with the stimulus. It will probably talk about making a distinction in order to show that two things aren't fair to compare.
