问题     SIGG’s trendy aluminum water bottles have scored a lot of free advertising in recent years. SIGG has been【67】for more than 100 years. Much of its【68】can be【69】to research publicized in 2007 about BPA’s【70】safety. The Swiss brand became the must-have as consumers rushed to find【71】to plastic bottles that【72】bisphenol-A (BPA) , a【73】chemical used to harden plastics, which some studies have linked to diabetes, premature puberty in girls and reduced sperm count in men. SIGG was one of the companies【74】profit from all the bad【75】over BPA. SIGG’s reusable aluminum bottles seemed the perfect solution both【76】the health and the environment.
    But many consumers are feeling【77】now that the company has been disclosed for failing to tell the public that its bottles were not【78】from BPA, at least not the ones that were manufactured before August 2008. While there’s no【79】showing the first-generation SIGGs did in fact contain BPA, there’s still plenty of complaining at the company’s lack of【80】. The news is【81】troubling since the company internally acknowledged the chemical’s safety problem as early【82】2006, when it quietly decided to formulate a new, BPA- free liner.
    To placate the masses, SIGG has【83】to exchange those older,  BPA-laden bottles【84】new ones through Oct. 31, but people are still feeling betrayed. Like many parents, I know, a couple years ago I tossed all the baby bottles I had-and any【85】sippers(虹吸瓶) too—and invested in SIGGs, which cost about $20 each【86】to find out we were going in the wrong direction.
选项 A、controversial
B、convertible
C、reversible
D、conversational
答案A
解析 本题考查词义辨析。一方面，BPA可以硬化塑料，这是优点；另一方面，BPA可以致病，这是弱点。所以，BPA是一种具有争议的物质。故选A)controversial“具有争议的”。
