- Hunting limits for snow geese were imposed many years ago in response to a sharp decline in the population of snow geese.
- It has been many years since the restriction led to the hunting season for snow geese being closed earlier than the scheduled date.
- The number of snow geese taken by hunters each year has grown every year for several years.
- As their population has increased, snow geese have recolonized wintering grounds that they had not used for several seasons.
- In the snow goose’s winter habitats, the goose faces no significant natural predation.
请问下各位答案是B，为什么呀。B选项最后翻译出来是什么意思。
还有一题：In the past, most children who went sledding in the winter snow in Verland used wooden sleds with runners and steering bars. Ten years ago, smooth plastic sleds became popular; they go faster than wooden sleds but are harder to steer and slow. The concern that plastic sleds are more dangerous is clearly borne out by the fact that the number of children injured while sledding was much higher last winter than it was ten years ago.
Which of the following, if true in Verland, most seriously undermines the force of the evidence cited?
A. A few children still use traditional wooden sleds.
B. Very few children wear any kind of protective gear, such as helmets, while sledding.
C. Plastic sleds can be used in a much wider variety of snow conditions than wooden sleds can.
D. Most sledding injuries occur when a sled collides with a tree, a rock, or another sled.
E. Because the traditional wooden sled can carry more than one rider, an accident involving a wooden sled can result in several children being injured.
答案是C。为什么不是E呢。C选项好像没有什么直接关系吧。
麻烦各位帮我解答下。谢谢
