第四段：A final test for the role of the Milky Way as an orientation cue for dung beetles would be to remove it completely from the real night sky. Fortunately, in October the Milky Way lies close to the horizon after sunset and is not visible for a beetle rolling within the walled arena. Previous experiments performed at this time of year show that the dung beetle S. zambesianus is unable to roll along straight tracks on moonless nights [7]. We are thus confident that when visible, dung beetles use the Milky Way for nocturnal orientation. 在你给四个段落选定小标题后，也可以思考选定的小标题对于写作过程是否有帮助，也许这四个小标题不会是呈现在论文中最终的小标题，但也许会对撰写每个段落是有帮助的。请大家在做这个测验时认真体会！
