Lesson 37 of the french course of Mova's primary school, as Mova's small model took its tests: it had read this lesson and the ones before it and learned from their exercises. Each test shows the options in the order the student saw them, its choice, the right answer, the score of every option and why it chose. The lesson itself, sentence by sentence with trees and pragmatics: the lesson in the corpora.

Every question of this lesson and each of its options parsed by Mova, with trees and pragmatics: the lesson's questions in the corpora.

Test 1 · ★★★ · wrong ✗

★★★ Zoe from Leeds goes, "Easy-peasy: quatre-vingt-dix-sept is 4, 20, 10, 7, so 42107." What did she do wrong?

2. 9, with 11 too — no support
3. 8, with 81 and 91 included — no support
4. 6, because 81 and 91 have no et — ← Mova's choice · ✓ the right answer · score 13

Why: It took the question to ask what it is done to. It chose option 4 with score 13, the only option with support. Its support: lesson 37, line 10: «From 1 to 99, only 21, 31, 41, 51, 61 and 71 contain the word et: 6 numbers; 81 and 91 have no et (quatre-vingt-un, quatre-vingt-onze).», reached through the same lesson line as the sentence the question matched.

Its support: lesson 6, line 12: «vingt means 20 and sounds like "van", through the nose; the g and t are silent letters left over from the old Latin word viginti.», reached through the option's own match among the sentences about the question's things.

The right option, 3, found no support in what it remembers. · the question and its options parsed, with trees and pragmatics

Test 7 · ★★★ · wrong ✗

4. Nothing, 3 is right — no support

Why: It took the question to ask who or what does it. It chose option 3 with score 10, against 9 for the next best.
