Read the following article and select the best answer. Article: The poorer mental function seen among alcoholics,many of whom also regularly smoke cigarettes,may be partly due to the long term effects of nicotine ,new research suggests. "People who are also smokers are at a much higher risk," Dr.Jennifer M.Glass of the University of Michigan's Addiction Research Center said. In her study,"Cigarette smoking has a bad effect on IQ and thinking," she said. This finding may seem counterintuitive ,since many smokers show that they feel quicker and focused after smoking. Indeed,research shows that improved mental functioning is one of the immediate effects of nicotine exposure. _ Studies show that up to 87 percent of alcoholics smoke cigarettes. Yet,few studies have looked into cigarette smoking as a factor that might explain the cognitive lack reported among alcoholics. To search for that association,Glass and her colleagues examined brain function among 172 men from the same area,including 103 men who abused alcohol. The team found that men with higher scores on the lifetime alcohol problems scale(LAPS)and those who reported a higher number of pack years of smoking both had lower IQ scores. Upon further research,the researchers found that smoking also appeared to be independently associated with weaker word and space reasoning. Thus,though smoking did not account for all of the decreased mental functioning observed among the alcohol abusers,it did seem to account for some of the effects,the report indicates. Question: What is the passage mainly about? - Cigarette smoking contributes to decreased IQ and thinking. - Alcohol abuse is to blame for the poorer mental function. - Most of the alcoholics are also heavy smokers. - Non-smokers mostly have higher IQ scores.
(Answer)
Cigarette smoking contributes to decreased IQ and thinking.
