[单项选择]Since the Hawaiian Islands have never been connected to other landmasses, the great variety of plants in Hawaii must be a result of the long-distance dispersal of seeds, a process that requires both a method of transport and an equivalence between the ecology of the source area and that of the recipient area.
There is some dispute about the method of transport involved. Some biologists argue that ocean and air currents are responsible for the transport of plant seeds to Hawaii. Yet the results of flotation experiments and the low temperatures of air currents cast doubt on these hypotheses. More probable is bird transport, either externally, by accidental attachment of the seeds to feathers, or internally, by the swallowing of fruit and subsequent excretion of the seeds. While it is likely that fewer varieties of plant seeds have reached Hawaii externally than internally, more varieties are known to be adapted to external than to internal transport.
The passage supplies informat

B. Why are more varieties of plant seeds adapted to external rather than to internal bird transport
C. What varieties of plant seeds are birds that fly long distances most likely to swallow

根据下面短文回答下列问题。
Long long ago, there was a big lion (狮子) that lived in a zoo (动物园). One day, he was very hungry. When Bill, the keeper, gave him his breakfast, he ate it up quickly. Quite by mistake (错误) he ate up the keeper, too.
When it was time for lunch, Bill didn’t show up. So the other keepers sat down to eat, but they didn’t know why Bill was not there.
Suddenly there came a big sound from the Lion House. They went to see what the matter was. There they found the big lion looking very big and fat and not happy at all.
The keepers looked at one another and all of them said together. "Of course! The big lion has swallowed (吞下) poor Bill!"
Then they let the lion eat some medicine and put the lion to sleep for the operation (手术). They helped Bill to get out. Then, Bill felt well again.
