问题    We are used to the idea of aging in ourselves. We are so used to this that it comes as a surprise to find that there may be some animals that do not age.
   Sea anemones (海葵) are an example. Some have been kept for nearly a century without showing any signs of lifelessness. Some kinds of sea worms can even " grow backwards. " If kept in the dark and given nothing to eat, they get steadily smaller. They finally end as a ball of cells looking rather like the egg from which they came. Under good conditions the ball will turn back to a worm and start growing again. One could probably keep them growing and un-growing again and again.  [br] According to the passage, which of the following statements in NOT true?
选项 A、We can keep certain kind of sea worm growing and un-growing again and again.
B、Human beings will grow old and die.
C、An anemone is a kind of sea worm that can grow backwards.
D、Some anemones will live nearly a hundred years.
答案 D
解析 ABC选项文章都有提到，但文章并没有明确提到海葵能活多久。因此选D。
