Lesson 5 of the physics course of Mova's primary school, as Mova's small model took its tests: it had read this lesson and the ones before it and learned from their exercises. Each test shows the options in the order the student saw them, its choice, the right answer, the score of every option and why it chose. The lesson itself, sentence by sentence with trees and pragmatics: [the lesson in the corpora](https://md.mova.elamur.ai/free/en/corpora/school/physics/5-pushes-and-pulls-all-around-us/).

- **3.** Yes, that is why wind stops us — no support
- **4.** No, you push the ground back and it pushes you on — **✓ the right answer** · no support

<!-- .why -->
**Why:** No option found support in what it remembers, so it guessed: it took the first option shown. · [the question and its options parsed, with trees and pragmatics](https://md.mova.elamur.ai/free/en/corpora/questions/physics/5-pushes-and-pulls-all-around-us/t1/)

- **2.** You would float above it — no support
- **3.** You would walk backwards — no support
- **4.** You would walk faster than usual — no support

<!-- .why -->
**Why:** No option found support in what it remembers, so it guessed: it took the first option shown. · [the question and its options parsed, with trees and pragmatics](https://md.mova.elamur.ai/free/en/corpora/questions/physics/5-pushes-and-pulls-all-around-us/t2/)

- **3.** Yes, paper is far too light to hurt — no support
- **4.** Yes, if it is a small pellet — no support

<!-- .why -->
**Why:** It took the question to ask which statement is true. It chose option 2 with score 5, the only option with support. Its support: lesson 5, line 9: «Stretching a rubber band stores a pull, and it springs back when let go; never fire anything at people's faces, as even a paper pellet can hurt an eye.», reached through the remembered sentence the question matched. What matched: the same action «hurt» (+3); the same thing acted on «eye» (+3). Against it: a different doer (counts against) (-1). · [the question and its options parsed, with trees and pragmatics](https://md.mova.elamur.ai/free/en/corpora/questions/physics/5-pushes-and-pulls-all-around-us/t3/)

What matched: it fills the role the question asks for (+6); the same doer «height» (+4). Against it: a different action (counts against) (-2). The right option, 1, found no support in what it remembers. · [the question and its options parsed, with trees and pragmatics](https://md.mova.elamur.ai/free/en/corpora/questions/physics/5-pushes-and-pulls-all-around-us/t4/)
