Test 6 · ★★★ · Deep time and the story of life

What would probably have happened if the asteroid had missed Earth 66 million years ago?

Mova's choice: option 2 · The right answer: option 3 · wrong ✗ · What happens: happen, miss · To what, where: asteroid

This is test 6 · ★★★ of lesson 58 «Deep time and the story of life» of the geography 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.
