Please help me with a hook sentence!!

In wars, secret codes are used to hide information from the enemy.

Explanation:

Honestly, a hook sentence just can be a random fact, question, or whatever that is related to your claim/thesis.

For example, a question could be, "Have you ever created a secret code with someone?"

A fact could be, "About 420 people were Navajo code talkers in World War II."

Just put something interesting and it works!

Maker fairs, diy groups, jam bands, and open mic events are all great opportunities that people can experiment with art and technique. Their work may not be a knockout success every time.
Hope this helped you!
