Read these lines: "Researchers gave juice boxes with straws to two groups of captive chimpanzees. The first group dipped the straw into the juice box, and then sucked on the small amount of juice at the end of the straw. The second group sucked through the straw directly, getting much more juice. When the first group observed the second group, all of the dippers switched to sucking through the straws directly." Which statement best expresses the main idea of the quoted lines?
AThe chimpanzees preferred juice boxes to every other kind of treat
BThe first group taught the second group how to dip their straws in
CThe chimpanzees shared their juice equally after the straws ran out
DThe chimpanzees switched to a better method just by watching others
Answer & Solution
Correct answer: D. The chimpanzees switched to a better method just by watching others
1. The quoted lines contrast two methods: dipping the straw gets a little juice, sucking through it gets much more.
2. After the dippers watched the suckers, every dipper switched to the better method.
3. The point of the whole account is that watching alone produced the change, option D.
4. Option B reverses who copied whom: the dippers changed, not the suckers.
5. Preferences for juice boxes and sharing are never discussed in the quoted lines.
