Test 2 · Plants deeper: leaves and sunlight, how a tree is made of…

What would happen if a leaf had all its stomata blocked with grease?

Mova's choice: option 4 · The right answer: option 3 · wrong ✗ · Who acts: leaf · What happens: happen, have, block · To what, where: stomata

This is test 2 of lesson 251 «Plants deeper: leaves and sunlight, how a tree is made of air» of the biology 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.
