[問題]問一題邏輯
問一題補習班給的題目：
Clay absorbs radiation with time, releasing it only when heated.
By heating a clay sulpture and measuring the radiation it releases,
experts can determine to within a century when the sculpture was last
heated.
The original firing of the finished sculpture might be the occasion of
that most recent heating
Experts who obtain the year A.D. 1450 as an estimate for a given sculpture
using the method described above would thereby most seriously undermine
any claim that the sculpture was made in
(A)A.D 1000
(B)A.D 1400
(C)A.D.1450
(D)A.D.1500
(E)A.D 1900
答案是E
我想問為什麼A不可以？
麻煩大家了～
謝謝！
