Translation:If he is willing to fly, then he is crazy and he does not have to fly, but if he is not willing to fly, then he is sane and he has to fly.
oh I love the Catch-22 reference
Just a heads up.... the word scramble on this one does not work, due to the words not being able to all fit on the screen at once for the word scramble.
I hit a report--but was not able to explain how "the answer was unnatural" in that report... as the word scramble makes it so you cannot answer it via that method.
you can also try reducing the screen size! I found that all the words showed up at around 80% (zoom-)
I'm not sure if we can disable specific exercise types for a given sentence.
Isn't it possible to switch from a tapping exercise to a typing exercise, though? At least on the website version, there should be a little icon at the very bottom that lets you do so. (Or is that hidden by the tiles in the word bank?)
There is a comment, "The answer was given automatically." Has anyone else seen this? What kind of exercise was it? Tell us more. I managed to get it only as a listening exercise, and I definitely had to type it all out.
I have an educated guess. There's a new bug that I've experienced myself, though not on this sentence yet. On tile exercises where the sentence is long and the tiles get pushed off the bottom of the screen, Duo fills in the tiles that have gone off the bottom of the screen. In a really long sentence it can actually fill in all the tiles. I've seen both partially filled sentences and twice I've encountered fully completed tile exercises where all I had to do was click submit. This sentence is long enough that it could well be that bug.
Of course there is nothing any contributor can do about it, so such a report is wasted. The correct procedure would be to take a screen shot and file a bug report.
