问题 According to the passage, color blindness can be dangerous in certain occupations like ______. [br] Why can’t bats and adult owls see colors according to the passage?

选项

答案 Because they have no cones.

解析 题目问为何蝙蝠和成年猫头鹰无法分辨颜色。根据关键词bats和adult owls定位第三段,该例是为了说明此段的主题句,即:Birds and animals which hunt at night have eyes which contain few or no cones at all,so they cannot see colors,由此得出答案。
