For me it depends, if it is something that is a fact (states in the US, France's Capital, currency in Italy) then I don't get why you just don't google it.
If it is along the lines of: why does America have 50 states? When and why did Paris become France's capital, and why is the Euro Italy's currency, when it used to be the Lire? Even if you can google all of this and get answers, sometimes it is good to have someone actually explain it to you, and you can ask questions to better understand why, and I will try to answer if I know what they are asking.
