| Scotland Yard’s top fingerprint expert,
Detective Chief Superintendent Gerald Lambourne had a request from the British
Museum’s Prehistoric Department to focus his magnifying glass on a mystery.

The blunt instruments he pored over were the antlers of red deer, dated by a radio-carbon examination as being up to 5,000 years old. They were used as mining picks by Neolithic man to hack flints and chalk, and the fingerprints he was looking for were of our remote ancestors who had last wielded them. The antlers were unearthed in July during the British Museum’s five-year-long excavation at Grime’s Graves, near Thetford, Norfolk, a 93 -acre site containing more than 600 vertical shafts in the chalk some 40 A. to assist in filling in detailed picture of early miners B. to throw light on an interesting aspect of early man’s methods of work C. to provide information about the organization of work D. to tell the purpose of using these antlers [单选题]国防具有（）国家的发展职能。
