It's looking for a gotcha moment to take out of context. During the last Australian federal election the then-Opposition leader (now Prime Minister) was asked what the Reserve Bank cash rate was and he didn't know off the top of his head. The media and now-former government tried to beat it up as a big problem and proof that he wasn't fit to be PM, which is ridiculous (though his actual performance as PM so far is underwhelming). It did lead to a great moment a couple of days later though when they tried it on the leader of the Greens, who just replied "Google it, mate".
It's like when they ask someone "What is a woman?" like it's some gotcha. Whatever you answer, they'll find a way to twist, exaggerate, or simply lie about.
