# Exam question 2 · Batteries, circuits and how electricity flows

<!-- .ven lang=en -->
Which of the following statements most accurately characterises the function of a fuse?

<!-- .vintro -->
**Mova's choice:** option 1 · **The right answer:** option 3 · wrong ✗ · **What happens:** follow, characteris · **To what, where:** function

<!-- .vabout -->
This is exam question 2 of lesson 27 «Batteries, circuits and how electricity flows» of the physics 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](https://md.mova.elamur.ai/free/en/school-run/physics/27-batteries-circuits-and-how-electricity-flows/#e2).
