Atticus agrees with Mr. Nathan Radley that the oak tree is dying.
True
False

false i think . sorry if i got it wrong

False

Explanation:

When Jem questions Atticus about the cemented tree, Atticus states that the leaves are green and full and that there are no brown patches;

I quote "that tree's as healthy as you are Jem".  

However, once Jem states that Mr. Radley said it was sick and dying, Atticus said "maybe it is".

So, due to his prior statements and the fact that he said maybe, rather than totally agree, would lead this question to be false.

Hope it helps.
