This sentence pretty much sums up what the writer of the passage wants to talk about. The other ones do not fit with the sentence “water is one factor that is necessary for growth” and do not fit the idea of the passage, which is what factors affect plant growth.
Since you used the name Scout, I'm guessing this is about "To Kill a Mockingbird". Hopefully I'm correct, but here we go. Scout has a new teacher when she starts going to school again. Scout already knows how to read. Every night, she and Atticus had read books together, and he had therefore taught her to read. Now, in school, they were learning to read. Since Scout had already learnt, she didn't need help. The teacher, however, did not like this. (Sorry, I can't remember the teacher's name for the life of me!) The teacher told Scout to tell Atticus that they can't read together anymore. Scout is very obviously upset. She believes she should be able to read with Atticus because she is learning, after all. So, she dislikes the school's new approach to teaching. Hope this helps you!
