Lesson 37 of the money 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 · ★★ · right ✓

Josh says, "UK doesn't grow bananas cos it's too cold, innit." His mate says, "Nah, it's cos bananas are banned." Who's right?

  • 1. Neither: the UK actually grows most of the world's bananas — no support

Why: It took the question to ask which statement is true. It chose option 3 with score 3, the only option with support. Its support: lesson 37, line 2: «Countries trade because each is good at different things: bananas need about 27°C and Britain's summer days are often around 20°C, so hot countries grow banana…», reached through the same lesson line as the sentence the question matched.
