3. 问句"What does the story tell you?"是询问故事传递的信息，E选项"It tells me there are different stars in space."（它告诉我太空中有不同的恒星）的主语it对应问句里的the story，回应了故事的内容，二者匹配。
4. 问句"Are there any aliens on that planet?"是询问对方是否认为那个星球上有外星人的一般疑问句，A选项"No, I don't think so."（不，我不这么认为）是符合语境的观点回应，二者匹配。
5. 问句"What can you see in the sky at night?"是询问夜晚能在天空看到的事物，D选项"We can see the Moon and the stars."（我们可以看到月亮和星星）正好回应看到的景物，二者匹配。
