A near impossible literacy test Louisiana used to suppress the black vote

Actually: Paris in the the spring

'the' comes twice

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

And the person who answered wrote the last two words such that they're not "on the line provided", so regardless of which phrase they're supposed to write, they got the question wrong.

Assuming they did write the correct thing, and assuming the test administrator would be unusually generous about the placement of the words, they still got it wrong: they left off the colon at the end.

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.
