Transportation Decision Transportation decision consists of the following parts: 1.Selection of the mode is determined by the consideration of distance,cargo weights,linkage,timing and other requirements.Generally speaking,rail has high fixed cost and the relatively low variable cost.It can move heavy,large quantity of cargo in the long distance.But,rail is disadvantaged because of the longer transit time and less frequent service than motor. Motor carriers such as truck companies offer door-to-door service,that is,the cargo can be shipped from the shipper＇swarehouse to the consignee＇s.Trucking fixed cost is the lowest of any carrier,because the equipment is fairly cheap and the motor carriers do not have to invest in the roads on which they run their operations.However,their variable costs are very high.Its expenses include two major components:firstly,the pick-up and delivery costs;secondly,there are gas or fuel costs,labor expenses and toll roads fees to be paid to highway and toll road operators Therefore,motor transport is good for cargo with small quantity to be shipped within short distances. Water is the predominant choice of transportation as it has the capacity to take greatest quantity,travel longest distance with lowest cost.Transport by sea accounts for 80% of in-ternational trade.The major expenses for water are expenses associated with investment and maintenance of the ships and terminals.For example,a 100000-ton container ship costs US$ 200 million.Terminal associated costs include harbor fees and the cost for loading and unloading the goods. Transport by air has the highest cost but it is fast with the lowest ratio of loss and dam-age.If you need to deliver an urgent order,there is little choice but by air. 2.Transport service provider is selected for its experiences,equipment,services and prices.Competitive in the transport industry usually drives the prices down and motivates for better services.A company also chooses its transport service provider because of its long-standing business relationship with certain shipping companies. 3.The alternative routing and scheduling is specific for motor only because railway and water have strict route and timetable.Motor has special advantage in terms of flexibility.It has the ability to load goods at greater frequency,travel through different routes and making deliveries to different loca-tions.Questions:

How is the transportation mode selected?( )

A:By suppliers. B:By customers. C:By consideration of distance,weight,linkage and other requirements. D:By government requirements.

A new anti-cheating system for counting the judges’scores in ice skating is flawed, according to leading sports specialists. Ice skating’s governing body announced the new rules last week after concerns that a judge at the Winter Olympics may have been unfairly influenced.
Initially the judges in the pairs figure-skating event at the Winter Olympics in Salt Lake City voted 5 to 4 to give the gold medal to a Russian pair, even though they had a fall during their routine. But the International Skating Union suspended the French judge for failing to reveal that she had been put under pressure to vote for the Russians. The International Olympics Committee then decided to give a second gold to the Canadian runners-up (亚军).
The ISU, skating’s governing body, now says it intends to change the rules. In future 14 judges will judge each event, but only 7 of their scores—selected at random—will count.
The ISU won’t finally approve the new system until it meets in June but already UK Sport, the British Government’s sports body, has expressed reservations. "I remain to be convinced that the random selection system would offer the guarantees that everyone concerned with ethical sport is looking for", says Jerry Bingham, UK Sport’s head of ethics (伦理).
A random system can still be manipulated, says Mark Dixon, a specialist on sports statistics from the Royal Statistical Society in London. "The score of one or two judges who have been nobbled (收到贿赂) may still be in the seven selected."
Many other sports that have judges, including diving, gymnastics, and synchronized swimming, have a system that discards the highest and lowest scores. If a judge was under pressure to favour a particular team, they would tend to give it very high scores and mark down the opposition team, so their scores wouldn’t count. It works for diving, says Jeff Cook, a member of the international government body’s technical committee. "If you remove those at the top and bottom you’re left with those in the middle, so you’re getting a reasonable average."
Since the 2000 Olympics in Sydney, diving has tightened up in its system still further. Two separate panels of judges score different rounds of diving during top competitions. Neither panel knows the scores given by the other. "We have done this to head off any suggestion of bias," says Cook.
Bingham urged the ISU to consider other options. "This should involve examining the way in which other sports deal with the problem of adjudicating (裁定) on matter of style and presentation," he says.
According to the new rules proposed by the ISU, which of the following is right

A:The number of judges will be doubled. B:Only half of the judges wilt score. C:Only some selected judges will score. D:Only half of the scores will count.
