A FEMALE contestant on the Turkish version of Who Wants To Be A Millionaire? could well be the world’s worst after she was stumped by the question ‘Where is the Great Wall of China?’

Su Ayhan, 26, was asked for her fourth question “Where is the Great Wall of China?” and given four options to chose from – China, India, South Korea or Japan.

But that stumped her and she opted to use one of her lifelines to help.

She asked the audience but they were pretty much clueless as well, with just 51 percent of them getting the answer right.

Still undecided she then chose to ask a friend – fortunately they were able to provide the correct answer of China.

But the hapless contestant came a cropper on the very next question which was about the composer of famous Turkish song and left the show.

Su has since become the butt of jokes in the country for her lack of knowledge but others have put blame with the Turkish government for failing educational standards in the country.

Ahmet Hakan, a journalist for The Hürriyet Daily News, said: “I hope many people in the audience failed to answer the question thinking it was too easy to be asked, setting a trap.

“Otherwise, this huge ignorance problem cannot be solved, even with our new Education Minister Ziya Selçuk.”

Su has defended her actions by saying: “I could use my lifelines whenever I wanted.”

It’s not the first time a contestant has spectacularly crashed and burned on the show which is a huge hit around the world.

In 2015 US student Brenton Andresik, flunked his very first question after telling the host just how brainy he was.

Mr Andreasik was asked: “Snapping selfies in kitchens you can’t afford and taking a ‘meatball break’ are two things BuzzFeed says every twenty-something does on their first trip … where?”

He selected Rome — while the correct answer was Ikea.

Last year a contestant in Spain failed to get a question right despite him having the answer printed on his t-shirt.

Alberto appeared on the show with a Captain America t-shirt and was asked “Who is Steve Rogers?”

The hapless contestant opted for doctor, which meant he missed out on $150,000.
