[单项选择]Passage Two Questions 66 to 70 are based on the following passage: Every human being has a unique arrangement of the skin on his fingers and this arrangement is unchangeable. Scientists and experts have proved the uniqueness of fingerprints and discovered that no exactly similar pattern is passed on from parents to children, though nobody knows why this is the case. The structure on a person’s fingers does not change with growth and is not affected by superficial injuries. Burns, cuts and other damage to the outer part of the skin will be replaced in time by new skin which bears a reproduction of the original pattern. It is only when the inner skin is injured that the arrangement will be destroyed. Some criminals make use of this fact to remove their own fingerprints but this is a dangerous and rare step to take.
