Exam question 4 · What is everything made of?

Ascertain the mass of the water obtained upon the complete melting of an ice cube whereof the mass is ten grams.

Mova's choice: option 1 · The right answer: option 1 · right ✓ · Who acts: you, mass · What happens: ascertain, obtain, be, melt · To what, where: mass, water, ten grams, ice cube

This is exam question 4 of lesson 1 «What is everything made of?» of the chemistry course of Mova's primary school, asked in stiff, formal language. 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.
