Npcs dialogues repeats the player's last words

When talking to npcs, for example asking them a question, their first words it’s always the beginning of the last words from the player. Always. Example:

(Player): “Does your weapon deals enough damage?” (Npc) : “My weapon dealing more damage? Yes I guess.”

(Player) : “Hey, I have a mystery box for you. Let me know what you think.” (Npc): “A mystery box ? Okay sounds good.”

Can npcs just answer the question directly? It’s more realistic.
