【正文】 to prefer circles to ovals, whether they are iridescent or not（3）What will be talked about in the following paragraph? A.B. In a similar way, we were asking whether iridescence, due to its changeability, could work as a form of camouflage by preventing shape recognition. Kjernsmo and her colleagues trained bumblebees to associate a particular shape—a circle or an oval—with a sugar reward. And they found that the bees, when given a choice, would preferentially visit the shape they knew to be sweet. But when the shapes were iridescent, the bees had trouble telling them apart. It seemed that the strikingly iridescent surfaces on our targets visually broke up the otherwise recognizable shape of the targets, which made them hard to distinguish. As for making use of this method for hiding in plain sight, Any practical applications is of course directly linked to any industry that has an interest in camouflage, that is how to conceal objects or make them more difficult to recognize. The researchers are currently conducting experiments with birds, which often prey on iridescent insects to see if it helps to have a bird39。t a new one. The father of camouflage theory, Abbott Thayer, really believed that iridescence should be categorized as a camouflage strategy. And he wrote in his famous lifework Concealing173。根據(jù)第一段中的“While you39。D. living environment.Honey（2）What is the 2nd paragraph mainly about?

When the researchers played recordings of flying bees to evening primrose flowers, within three minutes the sugar concentrations in the nectar (花蜜) of its flowers increased. The fluid, produced to attract pollinating (授粉) insects, was on average 20 percent higher in flowers exposed to the buzz pared to those left in silence or exposed to higher pitched sounds. Professor Lilach Hadany, who led the study, said: Our results document for the first time that plants can rapidly respond to pollinator sounds in an ecologically relevant way.2．犇犇閱讀下列短文，從每題所給的A、B、C和D四個選項中，選出最佳選項。 （3）考查推理判斷。D.AmbiguousIt offers an effective method to solve the problem of ewaste.B.Ewaste in the world is increasing significantly.B.
