Awkward title probably, but lemme explain:
The question is “This piece of French architecture was finished on January 26, 1887.” You know this is the Eiffel Tower. But when you buzz in and give the response, you say:
“Who is the Eiffel Tower?”
Would you be awarded the points for being correct, or docked the points for being incorrect since you didn’t say “WHAT is the Eiffel Tower?”
Some contestants phrase every question with “What is…?” Matt Amodio is well known for doing this. He won many times.
Which is technically correct, since you are answering “What is [the answer]?”
That’s a super smart strategy. It reduces the amount of thinking required and speeds up your ability to answer.
