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.
