Watson can offer explanations of facts and or events. For example "Why did the UK vote to leave the EU?" There should be options to specify breath and depth of response. A 14 year old middle school student wants one level and a college professor of political science wants a different level. Likewise a conservative want their point of view included and a liberal wants their point of view included in the response. Though both may prefer to have the opposing view point down played. Watson will need to know its audience.
Simple scientific events like why does the moon show phases in the night sky will require less tailoring to please the questioner.
