That's one trick part of the the question (a common trick, a lot of people don't read two "the"s in a row), but the other answer could be "what you read in the triangle below" as that's what the question states.

The other trick is that the line could be too short depending on your handwriting, in theory disqualifying the tested person regardless of what they write down.

That's diabolical. But it's not certain if even that's correct. Depends on how the comma should be interpreted.
