[单项选择]I was not at all happy at the prospect of the 700-mile drive from Dar es Salaam to Nairobi. It was not that I disliked driving but I suspected that what is a very pleasant trip in the dry season could prove disastrous during the long rains, and the monsoons had arrived the previous week. I was fully aware of the possibility of a breakdown, of hitting large animals as they stopped, dazzled by my headlamps, or even of skidding off the road. But these dangers worried me much less than the thought of the stretches of black cotton soil I would have to negotiate, gray and hard as concrete when dry, but a black, viscous, muddy mess with the consistency of elastic after just one heavy shower of rain. However, I had to be in Nairobi by the weekend so there was nothing for it but to drive; all planes were fully booked three weeks ahead and with the railway line washed out there was little likelihood of a train in the next few days.

C. was made of tar barrels
D. was in ideal working conditions

A teenager was unable to call an ambulance after her parents were shot in February because the family’ s internet phone service did not offer access to the 911 emergency number. A baby died in March for the same reason. Sad tales such as these led America’ s Federal Communications Commission (FCC) to vote on May 19th to require internet phone companies to offer a 911 service.
In so doing, the FCC seemed to have taken its first, big step towards imposing traditional telecoms rules on the internet--a contentious move given the fears that this will strangle what many still regard as an infant industry, especially if regulators elsewhere follow suit. But are the new rules really so bad
The new rules uphold a subset of telecoms policy, social objectives, which is much less burdensome than the FCC’S hugely unpopular economic regulation. Many providers of internet telephony--strictly, Voice over Internet Protocol (VOIP)--have for y
