An answer on Jeopardy! has left viewers scratching their heads as contestants questioned their own geography and math skills.

The February 15 episode had the final category of ‘Landmarks,’ with the prompt: ‘The distance between its two legs at ground level is 630 feet, making it as wide as it is tall.’

Contestants Diandra D’Alessio, James Tyler and David Bederman were all competing for the final spot in the Champions Wildcard semifinals – but all three of them were stumped by the final question.

Diandra and David both guessed the Eiffel Tower in France, while James suggested Christ the Redeemer in Brazil.

However, neither of those was the correct response.

The answer was actually a little closer to home and was revealed to be the Gateway Arch in St. Louis, Missouri.

‘You can actually inscribe the arch in a square,’ host Ken Jennings explained.

Fans took umbrage with the description of the archway – questioning whether you’d call the support beams ‘legs.’

‘It’s not really tricky by the writers, legs is the official way it’s described by the National Park Service and by its architect. But if you’re not familiar with it, I can see how’d that be surprising.’

‘I guessed the Arc De Triomphe,’ shared another.

‘One thing is for sure, legs, ends, supports, the Eiffel Tower has more than two of them. And Christ the Redeemer has less than two of them unless he is secretly anatomically correct under that robe,’ they continued.

‘I don’t think the three of them can blame the writers for their miss.’

Viewers took to social media to shared their thoughts about the answer, many unhappy with the descriptor of ‘legs’ in the prompt

‘In the final Jeopardy tonight’s clue mentioned the landmark having two legs and two of the contestants answered with… the Eiffel tower??’ another exclaimed.

‘I’m yelling St. Louis Arch! The two legs was an important part of the clue,’ agreed another.

Construction of the Arch began February 12, 1963 and was completed on October 28, 1965. The north tram was opened to the public on July 24, 1967.

All three contestants answered Walk the Line, leaving out the letter I – which ended up costing them money and time.

Despite not answering correctly, Diandra made it to the semifinals in the Champions Wildcard tournament after finishing as the winner – walking away with a final total of $23,599.
