24. The death rate from heart disease has dropped
by half since the mid-1960s. However, studies
consistently find that the improvement has less
to do with treatment than with changes in diet
and lifestyle. In a 1988 study Dr. Lee Goldman,
a Harvard cardiologist, analyzed the decline in
cardiac death between 1968 and 1976. Even
though he could not account for all of it, he
traced more than half to the drop in cigarette
smoking and cholesterol intake. Roughly 20
percent of the drop was due to heart and
blood-pressure drugs, and only 3.5 percent to
bypass surgery. Goldman has lately updated
his findings, and he says the same basic lesson
still holds: "The impact of the costliest
interventions is minimal." 24. According to Dr. Lee
Goldman's findings................. 
A) most of the recent deaths occurred on account of
cigarette smoking and cholesterol 
B) only half of the deaths occurred because of
cigarette smoking and cholesterol 
C) some deaths are attributable to abortive surgical

pressure drugs
