句意:蚂蚁既聪明又团结。
根据文章第2~4行:He wants to take it home. The watermelon is too big for him, so he goes home and asks for help. A lot of ants come. They start to push the watermelon together(他想把它带回家。西瓜对他来说太大了,所以他回家寻求帮助。很多蚂蚁来了。他们开始一起推西瓜)可知蚂蚁们很团结。
根据文章最后四行:Then, they have an idea. They cut the watermelon into small pieces.(然后,他们有了一个主意。他们把西瓜切成小块。)
Finally, the ants put the watermelon peel in the puddle and make it a slide. Now they can carry the watermelon home.(最后,蚂蚁们把西瓜皮放在水坑里,使它滑动。现在他们可以把西瓜带回家了。)可知蚂蚁很聪明。
本句描述正确,故填T
