Exam question 4 · Vaccinations and why

Whereas a sufficient proportion of a population is immune, determine the consequence for persons who cannot be vaccinated.

Mova's choice: option 1 · The right answer: option 4 · wrong ✗ · What happens: be, determine, not vaccinate · To what, where: consequence, persons

This is exam question 4 of lesson 29 «Vaccinations and why» of the medicine 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.
