Test 5 · ★ · Wheels, axles, ramps and screws

If wheels had never been invented, what would happen to moving heavy things?

Mova's choice: option 1 · The right answer: option 1 · right ✓ · What happens: not invent, happen, move · To what, where: wheels, heavy things

This is test 5 · ★ of lesson 34 «Wheels, axles, ramps and screws» of the physics 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.

The options

Option 1 · ← Mova's choice · ✓ the right answer

It would be much harder, because sliding has far more friction
