Answer:
The statements by Mr. Lacey that best illustrates this change are:
* Worst looking place I've ever seen.
* I wouldn't leave an ant in that place.
* Are you going to feed it or not?
Step-by-step explanation:
Mr. Lacey is a very strict man and he has a really small family, just his wife and his daughter, so when a dog arrives he refuses to keep it and there are two events that make him change his mind, one is crying of his daughter and the other is the horrible place where the dog was going to stay so the expressions "Worst looking place I've ever seen." and "I wouldn't leave an ant in that place. " refer to the place and the last one "Are you going to feed it or not?" is him giving permission to his daughter to keep the dog.
