What is a likely reason an author chooses a particular theme?

So the theme of a book is the message it conveys. I would say the author chooses a theme to get a certain point across, maybe it's the authors way of giving their perspective on something.

boldness and strongness. don't let others bully you, stand up for yourself

explanation:

the most ethic and honorable thing for the newspaper to do are:

be completely transparent in reporting about the company’s attempt to trade favors.

contact other construction companies to tell them about the situation.

these two options are the most ethic because both promote the market fair course, by telling the other competitors about the company attempt to get ahead in the market by trading favors, the market is guaranteed equality and justice in the trading of goods and services.
