Read the dialogue then answer the question!

Ani: Hi, what are you reading?

Beni: I am reading this book about death penalty. It's said that death penalty started in eighteenth century.

Ani: That's interesting. How about now? Is the death penalty still used?

Beni: Yes, in some countries.

Ani: That's horrible. I don't agree with the death penalty.

Boni: Why?

Ani: It's because the death penalty violates the right to life. We're not God, so it's not our job to determine if someone must die.

Beni: That's interesting point. I have to agree with you.

Ani: Thank you.
