B, I just did it on the exact same site .
Explanation: I think his evidence is that he knows a lot of kids who matured more at 18 rather than 16 or 17 because at 18 your basically grown and during your growth you learned different things that helped you mature and understand stuff that you probably didn't know when you were younger. And you most likely take responsibility of the things you know you have too do than a 16 or 17 year old cause when your young you depend on your parents and grandparents to worry and do stuff for you now that your 18 that's your job to worry and do what you need to do so that's why i think the author is trying to explain to the reader. :) hope this makes sense lol
This is a quote from John Green's "A Fault in our Stars".
It's basically an exaggeration depicting the emotion of a reader who has just read a book that made a very strong impression on the person to levels that he wants everyone to read this book so as to feel the emotions that swell within John. This want is depicted by the phrase "weird evangelical zeal". The reader acknowledges that such a zeal is weird. Few things can make a person want to scream a message to the whole world which is the emotion the above exaggeration is describing. John simply desires for everyone to feel what he felt, but he knows it's most likely not possible to carry another person on the ride of intrigue he experienced, hence admitting that it is weird. There's an irony there because he knows it would be difficult for another to convey theirs to him too.
The exaggeration continues when the John declares that the world stands a chance of fixing itself only after it has read the book. Here John is simply implying that reading this book would be helpful to every reader in every circumstance.
They were too small and weak. They could not lift heavy objects or work for long hours.
