So, in another set of experiments, Kramer put identical food boxes around
the cage, with food in only one of the boxes. The boxes were stationary,
and the one containing food was always at the same point of the compass.
However, its position with respect to the surroundings could be changed by
revolving either the inner cage containing the birds or the outer walls,
which served as the background. As long as the birds could see the Sun, no
matter how their surroundings were altered, they went directly to the
correct food box. Whether the box appeared in front of the right wall or
the left wall, they showed no signs of confusion. On overcast days, however,
the birds were disoriented and had trouble locating their food box.
8. Which of the following can be inferred from paragraph 4 about Kramer's
reason for filling one food box and leaving the rest empty?
(A) He believed the birds would eat food from only one box.
(B) He wanted to see whether the Sun alone controlled the birds' ability
to navigate toward the box with food.
(C) He thought that if all the boxes contained food, this would distract
the birds from following their migratory route.
(D) He needed to test whether the birds preferred having the food at any
particular point of the compass.
答案A 可是我覺得B才對耶.....A好怪喔
