Orientation and Navigation (TPO11) 第八題~不會 - 英檢

第四段原文:

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 ofthe 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 thecorrect 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?

(1)He believed the birds would eat food from only one box.

(2)He wanted to see whether the Sun alone controlled the birds' ability to
navigate toward the box with food.

(3)He thought that if all the boxes contained food, this would distract the
birds from following their migratory route.

(4)He needed to test whether the birds preferred having the food at any
particular point of the compass.
