Who is the most famous person in the world? What is the best diet? Did Tony Soprano die? According to Ask.com, these questions are some of the most popular "unanswerable" questions of the last 10 years.

The search engine, formally known as Ask Jeeves.com, has compiled a top 10 list of questions which are supposedly impossible to truly answer, the BBC reported. The list of questions is based on an analysis of over 1.1 billion queries made since the website launched in 2000.

The list of "unanswerables" is part of a new promotion to celebrate the search engine's 10-year anniversary.

The search engine -- known for its trademark butler -- originally intended to answer users' questions and perform basic keyword searches. Now, 10 years later, the website is struggling for market share against more popular search engines, such as Google.
