Yes, I figured that would be an issue for anyone trying to replicate it. I do them in all three levels and I think I've experienced the issue in all three. I'd say there's a very good chance of seeing that type of multiple choice question in Level 1 before you get to 100. I can tell you some of the dialogues I've had to guess at and then maybe you can deduce the levels:
He calls the hotel to change his reservation.
He rents the car.
She stops for gas.
He goes to the bakery for several items.
He goes to the doctor's office.
They're planning the birthday party.
I'll pay closer attention to which level I'm doing when it happens, but I suspect it's in all three. It doesn't always register because I usually don't need the audio for recall. It started to happen intermittently maybe 2-3 weeks ago and now the dialogues are never available.
Also, there are intermittent glitches in the other forms of questions, as well. Like, Write It doesn't say the French, but you can just type something and proceed without it. Know It won't reiterate the answer after you say it, which is no big deal, but if/when Hear It malfunctions by not saying the French in the first place, it's locked up, and there's nothing you can do except abandon the test and reload the page. Again, these are relatively rare, and except for having it lock up on Hear It when you're at 95 with no errors yet, it's not really an issue.
p.s. I do these tests all the time, because it's great to be tested on things at random that you might not have seen in a year. On the one hand, because of the repetition in the questions, it can really help to burn some things in, but it'd also be nice to have more variability in the questions. I don't know how they're implemented or what you'd have to do to introduce a wider variety of questions, but it would be a nice option.
