Question

select the best evidence to support the statement that jem and the narrator remember certain events in their childhood differently.
when he was nearly thirteen, my brother jem got his arm badly broken at the elbow. when it healed, and jems fears of never being able to play football were assuaged, he was seldom self - conscious about his injury. his left arm was somewhat shorter than his right; when he stood or walked, the back of his hand was at right angles to his body, his thumb parallel to his thigh. he couldnt have cared less, so long as he could pass and punt.
when enough years had gone by to enable us to look back on them, we sometimes discussed the events leading to his accident. i maintain that the ewells started it all, but jem, who was four years my senior, said it started long before that.

Explanation:

The relevant text is "I maintain that the Ewells started it all, but Jem, who was four years my senior, said it started long before that." This shows a discrepancy in their memories of when the events leading to Jem's accident began, directly supporting the statement that they remember childhood events differently.

Answer:

The sentence "I maintain that the Ewells started it all, but Jem, who was four years my senior, said it started long before that." (or the relevant part of the text showing their different recollections)
