Elle est extrêmement séduisante.

English Translation

She’s extremely attractive.

I have the “Typing Color Hint” option enabled. As I was typing “att” into the cloze field for this sentence, the text was displayed in green, even though it didn’t match the correct answer, “séduisante”. After the fourth letter, “r”, the text was displayed in red. When I typed in the correct answer, “séduisante”, it was (correctly) displayed in green. When I typed a string that started with any letter other than “a” or “s”, it was (correctly) displayed in red. So there seems to be something special about the beginning string “att”. Maybe the contents of the cloze were changed at some point?
