Exam question 3 · The Moon

Ascertain the approximate gravitational acceleration at the lunar surface relative to that of the Earth.

Mova's choice: option 1 · The right answer: option 3 · wrong ✗ · Who acts: you · What happens: ascertain · To what, where: approximate gravitational acceleration, lunar surface relative

This is exam question 3 of lesson 6 «The Moon» of the space 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.
