[单选题]Ethosuzimide, which was developed in the 1950s, is commonly used to treat epilepsy, though it is no known precisely how the drug controls convulsions. There is no anecdotal evidence that it has had an anti-aglng effect in people. The next step, Komfeld says, is to test if the drugs have an anti-aging effect on animal like flies and mice。 Very little is known about the aging process. From genetic analysis, researchers have found that an in sulin-like signaling system regulates aging and longevity. A good diet can delay aging and extend a person life span. But scientists know virtually nothing about the effect of drugs on aging. “It’s a big void, ” Konfeld said。 In addition to delaying age-related degenerative changes, the drugs also increased neuromuscular activty, suggesting a link between the neuromuscular system and the aging process。

But Komfeld said scientists will not know about the applicability of the drugs in humans until a similar study is done on humans. “What’s very encouraging is that these drugs were developed to treat humans, and they are well understood, because they’ve been used for a long time, ” he said。

解析：空前文字提到：“有理由相信这种实验结论对更高级的动物，如人类，也同样适用”。所以这一空应该继续谈到实验结果对人类究竟是不是适用的问题。选项A提到：“但是科学家们目前还不知道究竟对人类是不是适用，除非也在人类身上做相同的实验”。显然，选项A最合适。
