Question : 24 of 98

Marks: +1, -0

Read the following paragraph and answer the question that follows:

An accurate measure of drug efficacy would require comparing the response of patients taking it with that of patients taking placebos; the drug effect could then be calculated by subtracting the placebo response from the overall response, much as a deli-counter worker subtracts the weight of the container to determine how much lobster salad you’re getting. In the last half of the 1950s, this calculus gave rise to a new way to evaluate drugs: the double-blind, placebo-controlled clinical trial, in which neither patient nor clinician knew who was getting the active drug and who the placebo.

Which of the options is a wrong answer to this question:

How does a double blind ensure a better trial of a new drug?

It gives rise to an unbiased testing of drugs.
The clinician cannot pick and choose patients to whom placebos can be administered.
It reflects the calculus exemplified by the deli-counter episode.
It increases the overall response to the drug.
The patient does not know whether he/she is getting a placebo.
