Test 5 · ★ · Electricity and safety

Why can a bird sit on a wire, but a squirrel touching the wire and the pole at the same time gets a shock?

Mova's choice: option 4 · The right answer: option 1 · wrong ✗ · Who acts: bird, squirrel · What happens: sit, touch, get · To what, where: wire, shock

This is test 5 · ★ of lesson 28 «Electricity and safety» 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.
