When you type a question in Google Search, it usually returns a full response to the top of the page. This suggested suggested response feature may offer time savings, but the answer you give may be totally wrong.
But why should he give incorrect ones? information Google?
The short snippets of information that are at the top of Google search results, on language of SEO are also known as "featured snippets," and are considered "rich answers," respectively. These excerpts are given a higher priority than ordinary results that do not contain the above tags. 
The above mentioned to understand how Google determines which snippets will be displayed from a post.
To determine the priority now uses a technology called Knowledge Graph database. However, this particular database cannot ascertain verified sources.
This means that Google's suggested responses can be posted at the top of the results page by any top search result, even if it was not the site that first published it.
How do these results reach the top?
An important cause is popularity, but it is not the only one. Google gives priority to links that answer directly to common questions, and links that answer these questions in the fewer words. Let's say that Google's search engine also likes the answers that offer the information in a list format. 
As you understand, it does not matter whether information is accurate or not. Examples of the past have proven this. Of course they were quickly removed as soon as they became viral:
An earlier entry of Google for Barack Obama referred him as "King of America," or many entries that said dinosaurs never existed.
Of course the wrong answers continue to exist. Why;
Google Search uses an automated procedure which decides whether to keep a quote or change it based on its performance. So a completely false quote could be marked as the top suggested answer until someone is found to point it out. Google is usually pretty quick to fix any such issue, but always after a holiday.
So it's best not to believe the first thing you read…
