Identify the mechanism by which many spiders adhere to vertical surfaces of glass.

Mova's choice: option 1 · The right answer: option 1 · right ✓ · Who acts: you, many spiders · What happens: identify, adhere · To what, where: mechanism

This is exam question 1 of lesson 148 «Spider-Man: real spider senses, climbing and bites» of the biology 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.
