There are four types of sentences. I'll list them below.
Interrogative sentences are questions: statements that end in a question mark (?). "What will they think of next?" is an interrogative sentence, as you can see from the question mark, so we can rule this one out.
Exclamatory sentences are statements that end in an exclamation point (!). "I simply adore cheese!" is one, because of its exclamation point, so this one isn't declarative either.
Now, things get a little trickier. There are two types of sentences that end in a period (.): imperative and declarative sentences.
Imperative sentences are commands--telling someone to do something. Which is imperative? "Please tidy your room." "We live in an amazing time." Obviously, "Please tidy your room" is an order, and so is imperative.
The only sentence left is "We live in an amazing time." This has to be a declarative sentence, which is simply a statement that ends in a period. This is a statement, and it ends in a period, so this sentence is a declarative sentence.
Answer: We live in an amazing time.
So this passage in question is chapter 23 pg 304
Leading into what he says, jem explains to scout that there are four kinds of folks, which leads them to talk about their family's background leading to the conversation of learning how to read and write where scout goes on and tells him "no everybody's gotta learn, nobody's born knowin'. That walter's as smart as he can be, he just gets held back sometimes because he has to stay out and help his daddy. Nothin's wrong with him. Naw, jem, i think there's just one kind of folks. Folks."
Which leads us to Jem saying "thats what i thought, too when i was your age. If there's just one kind of folks, why can't they get along with each other? if they're all alike, why do they go out of their way to despise each other? Scout, I think I'm beginning to understand why Boo Radley's stayed shut up in the house all this time...its because he want to stay inside."
My interapation of this is that Jem means the he thought that the trial wasn't equal. The thought that the world isn’t as good as he thought and believed. The Tom Robinson’s trial made it clear which made Jem come upon this relization. That the staying inside maybe meant he (boo radley) maybe was scared it may not be a very pleasant world, not fair and judgemental towards him
Hope this helps :)
