(C) Coffee drinkers might choose to eat along with their coffee foods contaming 　　substances that harm the heart
(D) Other beverages⁶ besides coffee might contain stimulants⁷ that have some 　　effect on the heart

3. A group of unusual meteorites⁹ was found in Shergotty. India. Their structure indicates that they originated on one of the geologically active planets. Mercury, Venus, or Mars Because of Mercury s proximity¹⁰ to the Sun any material dislodged from that planet s surface would have been captured by the Sun, rather than falling to Earth as meteorites, Nor could Venus be the source of the meteorites, because its gravity would have prevented dislodged material from escaping into space The meteorites, therefore, probably fell to Earth after being dislodged from Mars, perhaps as the result of a collision with a large object

　　The argument derives¹¹ its conclusion by

(A) offering a counterexample to a theory
(B) eliminating competing alternative explanations
(C) contrasting present circumstances with past circumstances
(D) questioning an assumption
(E) abstracting a general principle from specific data

4. Because quitting smoking is very stressful and leads to weight gain, it is difficult to do. The key to quitting however, may be as simple as replacing an unhealthy activity with a healthy one In one study half of htose attempting to quit were assigned to a smoking-cessation program alone, and the other half were assigned to the same program plus fifteen weeks of aerobic¹² exercise the one-month mark none in the first group had quit but 40 percent of those in the second group had not smoked

　　Each of the following, if true, provides some support for the argument EXCEPT:

(A) Regular exercise prevents weight gain
(B) Each group in the study included four hundred randomly¹³ selected 　　participants
(C) Nonsmokers accustomed to regular exercise do not gain weight when they 　　stop exercising
(D) Aerobic exercise can stimulate¹⁴ the brain s production of endorphins. which 　　reduce tension
(E) Of those in the second group in the study 38 percent had not smoked at the 　　one-year mark
