Damian, I also thought it was on the easy side. But, I was also (pleasantly) surprised at the high number of folks that got this right (69% at the time of this posting)... I've seen way too many people get this wrong.
I thought it was a good question. There's a wide range of members here with varying experience so what may be easy for some may not be for others. If it was "too easy", then everyone would be getting it correct. 🙂
The question was easy in a technical sense, but also had a psychological angle what with the "2", "three" number-word confusion. Sort of like the psych test (the "Stroop effect"), where you have to answer in what color a word is written, where the actual word is also a color, but different than the actual color (e.g., "Blue", written in red ink).
