Passage 2 Every year, the American Lung Association (ALA) releases its annual report card on smog, and every year it gives an "F" to over half the nation’s counties and cities. When ALA’s "State of the Air 2002" recently came out, dozens of credulous local journalists once again took the bait, ominously reporting that their corner of the nation received a failing grade. The national coverage was no better, repeating as fact ALA’s statement that it is "gravely concerned" about air quality, and neglecting to solicit the views of even one scientist with a differing view. Too bad, because this report card says a lot less about actual air quality than it does about the tactics and motives of the ALA. The very fact that 60 percent of counties were given an ’F’ seems to be alarmist. This is particularly true given that smog levels have been trending downward A. the increases above the smog standard B. the irregular readings about air quality in some areas C. the occurrences of smog in Los Angeles D. the current standards demanded by ALA [单选题]【单选题 1分】
