Section B
Directions：Read the following three passages．Each passage is followed by several questions or unfinished statements．For each of them there are four choices marked A，B，C and D．Choose the one that fits best according to the information given in the passage you have just read．
I used to think ants knew what they were doing．The ones marching across my kitchen counter looked so confident； I just figured they had a plan，knew where they were going and what needed to be done．How else could ants organize highways，build elaborate nests，launch impressive attacks，and do all the other things ants do？
Turns out I was wrong．Ants aren't clever little engineers，architects，or soldiers after all---at least not as individuals．When it comes to deciding what to do next，most ants don't have a clue．"If you watch an ant try to accomplish something，you'll be impressed by how awkward it is，"says Deborah M．Gordon，a biologist at Stanford University．
"Ants aren't smart，"Gordon says．"Ant colonies are．"A colony can solve problems unthinkable for individual ants，such as finding the shortest path to the best food source，assigning workers to different tasks，or defending a territory from neighbors．As individuals，ants might be tiny dummies，but as colonies they respond quickly and effectively to their environment．They do it with something called collective intelligence．
Where this intelligence comes from raises an essential question in nature：How do the simple actions of individual ants add up to the complex behavior of a group？How do hundreds of honey-bees make a critical decision about their hive （蜂巢）if many of them disagree？The collective abilities of such animals---one of which grasps the big picture，but each of which contributes to the group's success---seem miraculous even to the biologists who know them best．Yet during the past few decades，researchers have come up with fascinating insights．
