Test 5 · ★★ · Vents and trenches: tubeworms, iron snails, the Challenger…

What would happen to the tubeworms if a vent stopped pouring out hot chemical water?

Mova's choice: option 2 · The right answer: option 1 · wrong ✗ · Who acts: vent · What happens: happen, stop, pour out · To what, where: hot chemical water

This is test 5 · ★★ of lesson 177 «Vents and trenches: tubeworms, iron snails, the Challenger Deep and life without sunlight» of the biology course of Mova's primary school. The page gives the question's syntax tree — a dependency tree in the style of Universal Dependencies — and its pragmatics clause by clause, then the 4 options as the student saw them, each with its tree and pragmatics. Every text is parsed by Mova itself. How the student answered it, with the score of every option and why: the test at school.
