Reading readiness is like when you are ready to learn how to read
<h3>A) To inform the reader about the baseball game</h3><h3 />
The author of this article is informing the readers about the baseball game, he/she/they are telling the reader of the information. If we read it there is no opinionated statements, no evidence of persuading sentences, and no criticism of the players results. The author is informing.
Hope this helps. Good luck! :)
