33. The correct answer is C.

The passage that heart scans take less time than angiograms and

do not require recovery time. They are also more sensitive than

angiograms. But they use more radiation than other diagnostic

procedures. And finally, their sensitivity can result in detection of

harmless abnormalities that may worry patients. We are asked to

find among the choices a conclusion that can be drawn on the basis

of that information.

Choice A states that a heart scan is safer than an angiogram. We

are given no information about the relative safety of the procedures.

Incorrect.

Choice B states that patients should not be concerned about heart

abnormalities that appear in a heart scan. This misrepresents the

information in the passage. The passage simply stated that the

scans may pick up harmless abnormalities, not that all abnormalities

are harmless. Incorrect.

Choice C states that a heart scan could result in indirect harm by

causing a patient to undergo risky unnecessary procedures. This is

supported by the passage, which states that the scans could result

in undue concern and treatment. Correct.

Choice D states an angiogram is the appropriate treatment for most

patients. The information in the passage does not support this. In

fact, if anything, the passage would seem to support the

contradictory assertion that heart scans are more appropriate for

most patients. Incorrect.

Choice E states that a heart scan is more expensive. We are given

no information about cost. Incorrect.
