想请问Damaged nerves in the spinal cord do not regenerate
themselves naturally, nor even under the spur of
nerve-growth stimulants. The reason, recently dis-
covered, is the presence of nerve-growth inhibitors
in the spinal cord. Antibodies that deactivate those
inhibitors have now been developed. Clearly, then,
nerve repair will be a standard medical procedure in
the foreseeable future.

这题选A还是没有看懂，这道题如何说明inhibors主要功能并不是阻碍神经重生，它还有其它更重要的作用。如果使ngi失去活力了，它其它的功能无法完成，
