Please choose the correct ending to complete the given sentence: Education and Communications: [header] How to write a fiction book [title] What do you know? [step] That is the first question you should always ask yourself because if you don't know about something, how can you write a whole book on it? [title] Think up an idea. [step] It isn't as easy as you may think. Every book starts with an idea.

Ending1: If your idea is too abstract or too specific, it won't do the world justice. [title] Maybe the idea you come up with isn't one you wanted to try. Ending2: If you know something, consider even writing it down. You can even try to memorize all the steps, and think up an idea. Ending3: Something that works is imagining a really good beginning, asking questions about it, and sort of working out a plot line to go along with it. [title] Pick up a notebook and pencil, or get out your laptop, and brainstorm. Ending4: Some ideas look really good, but others they just sound silly. Find some that have been done before and try to come up with strong ideas.
