Lesson 23 of the technology 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](https://md.mova.elamur.ai/free/en/corpora/school/technology/23-airports-black-box-helicopters-drones/).

Every question of this lesson and each of its options parsed by Mova, with trees and pragmatics: [the lesson's questions in the corpora](https://md.mova.elamur.ai/free/en/corpora/questions/technology/23-airports-black-box-helicopters-drones/).

Its support: lesson 23, line 9: «The black box is really two tough recorders, one for flight data and one for cockpit sounds, and they are painted bright orange so they can be found.», reached through the remembered sentence the question matched. What matched: the same doer «black box» (+4); the same property (+2); the same light verb (be, have, do, get, go) (+2).
