Electronic cigarettes are handheld nicotine-delivery devices that, despite a devoted following, are currently swirling in controversy. New York is pushing to become the first state to ban the devices, which so far remain【C1】______and mostly unstudied. With cute colors, fruity flavors, clever designs and other options, e-cigarettes may hold too much【C2】______for young people, critics warn, offering an easy gateway to nicotine addiction. But those criticisms clash with【C3】______strong arguments for the value of e-cigarettes. The devices, which are tobacco-free, may be a safer【C4】______to cigarettes, say advocates, who point to thousands of smokers who say they have used e-cigarettes to help them quit.

No tobacco is【C6】______in e-cigarettes and there is no smoke either. Instead, as users breathe in, they take in nicotine-filled vapor.

M)eliminate N)detect O)identified
【C6】
选项
答案
E
解析
空格作句子表语,再结合其后的介词in,推断空格可能是分词。上文提到,电子香烟利用加热器对烟管里的尼古丁进行加热并使其雾化,由此可知这种香烟不需要用到烟草。involved“含有”符合上下文语义。
