[单项选择]For my proposed journey, the first priority was clearly to start learning Arabic. I have never been a linguist. Though I had traveled widely as a journalist, I had never managed to pick up more than a smattering of phrases in any tongue other than French, and even my French, was laborious for want of lengthy practice. The prospect of tackling one of the notoriously difficult languages at the age of forty, and trying to speak it well, both deterred and excited me. It was perhaps expecting a little too much of a curiously unreceptive part of myself, yet the possibility that I might gain access to a completely alien culture and tradition by this means was enormously pleasing.
I enrolled as a pupil in a small school in the center of the city. It was run by a Mr Beheit, of dapper appearance and explosive temperament, who assured me that after three months of his special treatment I would speak Arabic fluently. Whereupon he drew from his desk a postcard which an old pupil had sent him f

[单项选择]
In his book The Tipping Point, Malcolm Gladwell argues that "social epidemics" are driven in large part by the actions of a tiny minority of special individuals, often called influentials, who are unusually informed, persuasive, or well connected.

The supposed importance of influentials derives from a plausible-sounding but largely untested theory called the "two-step flow of communication": Information flows from the media to the influentials and from them to everyone else. Marketers have embraced the two-step flow because it suggests that if they can just find and influence the influentials, those select people will do most of the work for them. The theory also seems to explain the sudden and unexpected popularity of certain looks, brands, or neighborhoods. In many such cases, a cursory search for causes finds that so
