### HideShow timer Statistics

Doctors are trying out heart transplants using computer-aided techniques. These might be costlier than the old kind of surgeries, but would also be cost-effective, as these transplants will be more accurate. Thus patients would have more chances of recovery and the time taken for the surgery would be reduced.
Which of the following need not be studied in order to evaluate the truth of the above argument?

• The time taken in the two kinds of surgeries.
• The accuracy of the two kinds of surgeries.
• The chances of recovery from both the surgeries.
• The cost involved in both the kinds of surgeries.
• The recovery time taken by the patient after the surgery.

Passage states thet ...would also be cost-effective..., answer states that we DON'T NEED the recovery time taken by the patient after the surgery. So is the recovery time really don't influence costs?

The way I understood the passage, the new surgery would be more cost-effective on the doctor's end. The recovery time taken after the surgery is complete is on the patient and has no bearing on the doctor.

But as I typed that out, in case I'm wrong and the passage is talking about the cost-effectiveness being on the patient. Recovery time has no bearing on cost as it's just the time the patient is taking to rest and recover.

Thus patients would have more chances of recovery(OPTION C) and the time taken for the surgery(OPTION A) would be reduced.

• The chances of recovery from both the surgeries.

Only option E is irrelevant as you can see above
I have boldfaced the relevant part with the concerned option.

Hope this helps...!!

Actually in problems such as- Assumption, what should be good in order to evaluate statement, one should avoid restatement of the premises, evidences given in the stem. The right chice must be something new, which fills in the gap!

Only E states something that is not mentioned in the argument. So there is no need to evaluate it. We have to evaluate all other statements mentioned in the argument.

Which of the following need not be studied in order to evaluate the truth of the above argument?

DOc => HT using CAT
cost-effective but costly
1. Patient would have more chances of recovery
2. the time taken for the surgery would be reduced

=> what if no. of surgeries increased and in turn time taken will increase

should be B because we already know this from the premises : as these transplants will be more accurate
• The time taken in the two kinds of surgeries.
• The accuracy of the two kinds of surgeries.
• The chances of recovery from both the surgeries.
• The cost involved in both the kinds of surgeries.
• The recovery time taken by the patient after the surgery. :- E is not mentioned in premise but in conclusion, how do we know that recovery time taken by the patient after the surgery is less for surgery type 1 to type 2.
