The following dialog is for questions 4 to 6.

Raline: Rangga, have you decided the theme of our graduation book?

Rangga: Wait a second. I'm thinking of the city park.

Wisnu: We can't. Another class chose that place to take pictures yesterday.

Rangga: Oh, really? How about the zoo?

Anita: That's a good idea, but I'm afraid that the Scout club proposed there already.

Wisnu: Then, how about the water park?

Raline: Water park? Won't it be chosen by the swimming club members?

Wisnu: Probably, but the water park also has a beautiful park with a small lake.

Rangga: So, you mean we are going to take pictures at the park there, not the swimming pool?

Wisnu: Exactly!

Raline: That sounds great! Let's tell the others about this.

Anita: Let's go. I hope they agree.

Raline: I hope so.

From the dialog, we can conclude that ____.
