Google's answers aren't always that great. Google picks the snippet for a search result and places it in a special card that is supposed to provide a quick answer. When searching for [Cheapest Health Insurance], Google provides the following answer: "Don't wait to enroll! Humana can help you find a plan for you and your family with benefits you want and offers plans at a variety of prices. You must enroll in a plan by February 15 to have coverage in 2015!". Obviously, the snippet is an ad and not an informative answer to the query.
There are questions that are better left unanswered and this is one of them.
