Lesson 12 of the space 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/space/12-saturn-and-its-rings/).

Every question of this lesson and each of its options parsed by Mova, with trees and pragmatics: [the lesson's questions in the corpora](https://md.mova.elamur.ai/free/en/corpora/questions/space/12-saturn-and-its-rings/).

### Test 1 · ★ · right ✓ {#t1}

<!-- .q -->
My little brother thinks Saturn's rings are like a hard plastic hoop you could walk on. What is the truth?

- **1.** They are just light, with nothing there at all — no support
- **2.** They are one solid ring of rock — no support
- **3.** They are separate chunks of ice each orbiting Saturn — **← Mova's choice** · **✓ the right answer** · score 5
- **4.** They are a hoop of frozen gas you could skate on — no support

<!-- .why -->
**Why:** It took the question to ask which statement is true. It chose option 3 with score 5, the only option with support. Its support: lesson 12, line 5: «The rings have gaps swept clear by the pull of Saturn's moons, and they slowly lose ice that rains into the planet, so scientists still argue about how old the…», reached through the option's own match among the sentences about the question's things. What matched: the same doer «rings» (+4); the same circumstance (+2). Against it: a different thing acted on (counts against) (-1). · [the question and its options parsed, with trees and pragmatics](https://md.mova.elamur.ai/free/en/corpora/questions/space/12-saturn-and-its-rings/t1/)

- **3.** It should sink fast, as it is so heavy — no support
- **4.** It should melt away in the water — 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/space/12-saturn-and-its-rings/t2/)
