Test 7 · ★★ · Lenses and eyes

Why does a telescope with a bigger lens show fainter stars?

Mova's choice: option 1 · The right answer: option 4 · wrong ✗ · What happens: do, show · To what, where: telescope, fainter stars

This is test 7 · ★★ of lesson 22 «Lenses and eyes» 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.
