The correct answer is implements.
In the case where there are both the implements and the extends clause present in the class header, the convention is that the first one should be the implements clause, followed by the extends clause.
This makes sense because you first need to implement the meaning you want to talk about, and then you will extend upon it later.
So they won't be seen; so Atticus will be busy reading; because if they were killed they'd miss school instead of vacation and because it is easier to see inside a dark house in the dark rather than in the daytime.
Hope this helps
