Ana helps her grandpa plant bean seeds, waters them, and then waits through many days of nothing happening before green shoots finally push up through the dirt. The waiting is the middle of the story, which is what makes it a better retelling passage than one where something happens in every line.
Retelling in three parts is harder than answering questions, because nothing on the page tells a child where the middle stops and the end starts. Most children put the shoots appearing in the end box, and the more interesting answer is that the shoots are the middle and the end is Ana checking the garden every day now. Either can be defended, and that argument is the lesson. The second question, about why Ana thought the seeds were sleeping, is worth asking out loud even if the writing box is left short.
