※ 引述《Diablotin (咕嚕咕嚕)》之銘言：
: In experimenting with artificial suns, Kramer made another interesting
: discovery. If the artificial Sun remained stationary, the birds would shift
: their direction with respect to it at a rate of about 15 degrees per hour,
: the Sun's rate of movement across the sky. Apparently, the birds were
: assuming that the "Sun" they saw was moving at that rate. When the real Sun
: was visible, however, the birds maintained a constant direction as it moved
: across the sky. In other words, they were able to compensate for the Sun's
: movement. This meant that some sort of biological clock was operating-and
: a very precise clock at that.
: 7. According to paragraph 5, how did the birds fly when the real Sun was visible?
: (A) They kept the direction of their flight constant.
: (B) They changed the direction of their flight at a rate of 15 degrees
: per hour.
: (C) They kept flying toward the Sun.
: (D) They flew in the same direction
: 答案B 可是我覺得是A
: 大家覺得咧？
我個人以為答案B是沒錯的耶
因為鳥雖然本身會依照太陽而改變他們的方向
但是鳥並不會判斷Kramer所用的太陽是真的還假的
(文中是說Kramer用了一個人工太陽)
另外有說到鳥會設想他們所看到的那個太陽會以某個速率移動
所以Kramer得到一個結論是當真正的太陽出來時
鳥才會保持一個固定的飛行方向
如果有問題的話還請指正囉 ^^"
