In a hermit crab queue by size, what would happen if the biggest crab did not move into the new shell?

Mova's choice: option 4 · The right answer: option 1 · wrong ✗ · Who acts: biggest crab · What happens: happen, not move · To what, where: crab queue, new shell

This is test 8 · ★★★ of lesson 330 «Unusual pets: stick insects, giant snails, ant farms and hermit crabs» 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.
