Question Type:
Strengthen (a claim) or Explain/Resolve
Stimulus Breakdown:
GIVEN THAT hospitals are no longer doing hot temperature, bacteria-killing laundry for their staff,
HOW CAN IT BE THAT the officials believe this won't put patients at risk?
Answer Anticipation:
There isn't an argument here; it's more like a Paradox. We have counterevidence against this belief. It sounds like the staff will now be using residential washing machines, which don't get hot enough to kill a dangerous bacterium, so the staff's clothing might be more dangerous to vulnerable patients. We need an answer that goes against that story and makes us feel fine about this change. Maybe something else is going to kill the bacteria; maybe the bacteria isn't really a risk to the patients that these staff members will be around.
Correct Answer:
D
Answer Choice Analysis:
(A) Irrelevant, because we care about the risk to PATIENTS.
(B) Okay, but if the staff is getting at least some of the patients infeced, we're still putting patients at risk.
(C) This goes the opposite direction. If it turned out that most of the staff weren't using the on-site laundry in the first place, then this change of policy would have little effect.
(D) YES, this works. Residential WASHING machines don't kill the bacterium but residential DRYERS do.
(E) This doesn't help us feel any better about the bacterium in question.
Takeaway/Pattern: Ultimately this hinged on a distinction between laundry service (washing and drying) vs. residential washing (vs. residential drying). If we went to the answers asking ourselves, "Which of these can help convince me that we don't need to be worried about this bacterium infecting patients" we should have liked (D) the most.
