B - Out of scope. We have been given no information about the available defenses that the host insects bring to the table. C - All we know is that the wasps always lay exactly the right number of eggs. We have no information to determine whether the wasps learn this behavior or if it's something else (such as instinct). D - No information about the speed of death for overpopulated vs. underpopulated host insect eggs. E - No information about visual cues vs. any other cues. A follows directly from the argument (even if it doesn't really say anything of much importance). If you want to know the size of the smallest possible host egg, you could study these wasps' egg-laying behavior and make some calculations based on the data you collect. Sounds plausible. -- by 会员 Sharonluo33 (2010/5/12 14:44:14)
我觉得楼上乃正解,用自己的理解再描述一遍,就是说可以通过研究蜂下蛋的行为来观察蜂的蛋一般都多大,一般都下多少个,它们一般都选择把蛋寄存在多大的蛋里来,然后根据这些数据,计算出一般理论上最小尺寸的host egg应该多大size。。。
C不准确的原因是,虽然蜂确实可以将egg准确无误的下在合适的host egg里,但并不代表这种能力是通过经验得到的,兴许蜂是通过遗传得到的呢,所以可以排除C |
