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 Google give wrong information?
The short snippets of information at the top of Google's search results are, in SEO parlance, also known as “featured snippets,” and are considered “rich answers,” respectively. These passages are given higher priority, in relation to the usual results, which do not contain the above tags. 
The above mentioned to understand how Google determines which snippets will be displayed from a post.
To determine now the priority uses a technology called the Knowledge Graph database. However, this database can not verify verified sources.
This means that Google's suggested answers can be posted to the top of the results page from any top search result, even if the website who first published it.
How do these results reach the top?
An important reason is popularity, but it is not the only one. Google prioritizes links that directly answer common questions, and links that answer those questions in the fewest words. Let us mention that in searching machine Google also likes 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…
