Lesson 415 of the biology 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.
Test 1 · ★★ · right ✓
A label calls an underground storage part a corm. A learner objects that anything underground must be a root. Which fact answers the learner?
- 1. Corms are seeds waiting to sprout — score 5
- 2. Only roots are able to lie below the surface of the ground — no support
- 3. Corms are modified stems, not roots — ← Mova's choice · ✓ the right answer · score 7
- 4. Corms are dead parts with no buds — score 5
Why: It took the question to ask who or what does it. It chose option 3 with score 7, against 5 for the next best. Its support: lesson 415, line 9: «Not every underground plant structure is a root; rhizomes and corms are modified stems.», reached through the same lesson line as the sentence the question matched. What matched: the same thing acted on «modified stems» (+2); the same light verb (be, have, do, get, go) (+2); it fills the role the question asks for (+2); the same doer «rhizomes» (+1).
Test 2 · ★★ · right ✓
An old shoot has died back, but connected underground tissue remains alive. Which claim is too strong?
- 1. The underground tissue differs from that shoot — no support
- 2. Every part of the plant must be dead — ← Mova's choice · ✓ the right answer · score 3
- 3. One visible shoot is no longer growing — score 3
- 4. Living tissue may still carry buds — no support
Why: It took the question to ask who or what does it. It chose option 2 with score 3, tied with another option at 3 (the first shown, or the one claiming less beyond what it knows, wins). Its support: lesson 415, line 3: «In many plants, living underground stems have buds that can produce new shoots. A shoot dying back does not necessarily mean that every connected underground p…», reached through the same lesson line as the sentence the question matched. What matched: it fills the role the question asks for (+2); the same doer «connected part» (+1).
Test 3 · ★★ · right ✓
A gardener sees new growth beside an older shoot. What additional observation helps distinguish vegetative growth from a new seedling?
- 1. The number of words in a label — no support
- 2. Where that new growth is attached — ← Mova's choice · ✓ the right answer · score 5
- 3. The name given to the garden — no support
- 4. The colour of the gardener's gloves — no support
Why: It took the question to ask what it is done to. It chose option 2 with score 5, the only option with support. Its support: lesson 415, line 4: «A new shoot replacing an older shoot is new growth, not the old shoot turning young again. A shoot arising from an existing base need not have started as a new…», reached through the same lesson line as the sentence the question matched. What matched: it fills the role the question asks for (+3); the same thing acted on «new growth» (+2).
Test 4 · ★★ · wrong ✗
A plantain leaf and a lawn-plantain leaf share an English name. What should be checked before transferring a claim between them?
- 1. Whether both leaves were drawn in green — ← Mova's choice · no support
- 2. Whether the two labels use the same font — no support
- 3. Whether the name has the same number of letters — no support
- 4. Whether the same kind of plant is meant — ✓ the right answer · no support
Why: No option found support in what it remembers, so it guessed: it took the first option shown.
Test 5 · ★★ · wrong ✗
A diagram labels an underground rhizome as a stem. Why is being below ground not a contradiction?
- 1. Roots and stems are always the same organ — ← Mova's choice · no support
- 2. Stems cannot carry any living buds — no support
- 3. Every underground structure is a seed — no support
- 4. Position alone does not define the organ — ✓ the right answer · no support
Why: No option found support in what it remembers, so it guessed: it took the first option shown.
Exam question 1 · formal language · right ✓
A child sees one brown shoot beside a green shoot and says the brown one became young again. Which comparison would better explain replacement?
- 1. New growth from a continuing base beside an older part — ← Mova's choice · ✓ the right answer · score 6
- 2. A calendar whose dates run backwards — no support
- 3. A root changing into an unrelated species — no support
- 4. A fruit changing into a leaf — no support
Why: It took the question to ask who or what does it. It chose option 1 with score 6, the only option with support. Its support: lesson 415, line 4: «A new shoot replacing an older shoot is new growth, not the old shoot turning young again. A shoot arising from an existing base need not have started as a new…», reached through the same lesson line as the sentence the question matched. What matched: the same property (+3); it fills the role the question asks for (+2); the same doer «new shoot» (+1).
Exam question 2 · formal language · right ✓
A report records one bunch on one stalk and several replacement shoots. Which conclusion stays within that observation?
- 1. That stalk and those replacement shoots must be distinguished — ← Mova's choice · ✓ the right answer · no support
- 2. Every replacement shoot must come from seed — no support
- 3. Every plant fruits only once in its whole life — no support
- 4. Every underground organ is a root — no support
Why: No option found support in what it remembers, so it guessed: it took the first option shown.
Exam question 3 · formal language · wrong ✗
A survey counts one fruiting stalk on a banana plant, and a reporter writes that the whole plant is that single stalk. What is the error?
- 1. One fruiting stalk proves seeds were planted — ← Mova's choice · score 5
- 2. Banana plants never have any stalks — no support
- 3. A stalk count measures underground stems — score -2
- 4. A shoot is a part, not the entire plant — ✓ the right answer · score 4
Why: It took the question to ask what it is done to. It chose option 1 with score 5, against 4 for the next best. Its support: lesson 415, line 2: «Banana plants are large herbs. Their trunk-like pseudostem is formed by overlapping leaf bases, rather than the woody trunk of a tree. The visible shoot is one…», reached through the same lesson line as the sentence the question matched. What matched: it fills the role the question asks for (+3); the same thing acted on «one part» (+2). The right option, 4, scored 4.
