Topic 32 — Brain, senses and skin — the PP100's question types, with their exemplars

What this page is. James reads a bank as its question TYPES first (vault: A bank is reviewed as its question types first, one exemplar each). Under the Grade 5 standing brief the bank is built straight away (52 items in content/G5T32_pp100_bank.py); this sheet is the way in. Each type line says what the stem asks and what the four options (or the accept list) are, and prints one exemplar in full. Tags follow depth of reasoning — easy = one organ named from a scene, one fact, a one-step sort; medium = the rule applied to a fresh case, a reason picked, a drawn table or card read, two kinds of information told apart in one moment; hard = a word produced from a description, two ideas chained, the coined term judged among its sisters — and rise with the atom's position where the capstone's weight allows (LIF5-058 7 / 4 / 3; LIF5-059 the capstone 9 / 9 / 4; LIF5-063 4 / 7 / 5). Typed items are the hard tier's bulk (7 of 12 hard items; v2 after the non-author review retagged one definition pick medium); every typed key is a lexicon word a ten-year-old spells (brain, message, nose, tongue, eyes, skin, germs); "sensory organ" is never typed (RECALL_BY_MCQ) and is judged among four sister names instead.

Rulings already applied. Four options on every MCQ (fixed sets, each declared in KEY_TELL_EXEMPT_SETS: four of the five sensory organs; four of the five kinds of information; the four body organs); every stem a positive question of at most two sentences unless tagged hard; no claim item anywhere — the LIF5 register's SD-6 list names one belief (air and food share one tube) and it belongs to Topics 30 and 31, so no student is quoted and no verdict-and-reason option exists (the 28 Sep tiers as written; the 8 Oct conflict is left for James, no exception claimed); an item table or chain card prints one cell or box blank and its blind text lists the other cells as data; every item a fresh instance (the freshness grep in the build record: 0 lesson-scene hits); key letters A 9 · B 13 · C 12 · D 11 over 45 MCQs; KEY TELLS: 0 of 93 MCQs flagged.

The bar list (real things a generated item must never use): any lesson scene (Cleo's bike and the dog; the kitchen timer and cookies; Dalia's campfire, marshmallow, flames and smoke; Eli's soccer practice, scraped knee, coach, ice pack and sweat in the sun); any quiz, attached, summary, recall-bank or practice scene (the squirrel and the bark, the ducked ball, the traffic light, the wave, the lemon and the pickle, grandma's house, seven times eight, lightning, the kicked ball, the cat and the cupboard, the horse and the gate; pancakes, rain on a roof, a rainbow, a cold lake, a crunchy apple, the ocean's smell, a car horn; a scooter elbow, a washed cut on a hand, a snowball, a race, basketball, a blister, sun on an arm, a cut finger; popcorn, a barking dog let in; a raccoon and trash, a goat and a gate, a puddle, hot cocoa, buttered toast, a deer and a branch, a coach's whistle; the cat and its food, the rabbit and the fox, the duck and the cat); a hand pulled off a hot pan or any pain-withdrawal (not brain-first: never an example of the brain deciding); "nerve", "neuron", any brain region; "gravity is a force"; "non-US" animals (a hedgehog, a badger).

Draw constraints (⟂: never on one form together)

• Type 10's term item ("Which name fits the bear's ears?", plain wrongs a bone / a muscle / a hair) ⟂ type 7's and type 6's stems, which print "sensory organ" nowhere — no conflict; but ⟂ PR-11 and Lesson 2 (The sensory organs: what each one gathers), question 10 if a form ever mixes banks.
• Type 11's "which organ covers the whole body" ⟂ type 14's typed skin (the typed item's description is the MCQ's key).
• Type 2's "to the brain" items ⟂ type 5's typed message item (its stem says "send something to his brain").
• Type 14's typed germs ⟂ type 11's "what can get in through the cut" (key germs).
• Type 9's three tables each print four of the five organ-information pairs: any two type-9 items together hand over each other's missing cell — draw one per form.
• From the blind read (8 Oct 2026, adjudication): PP-13 ⟂ PP-14 ⟂ PP-15 (each row of the kinds table hands over the others); PP-28 ⟂ PP-14, PP-15, PP-46, PP-48; PP-29 ⟂ PP-09, PP-11, PP-45, PP-47; PP-30 ⟂ PP-08, PP-13, PP-45 (a drawn table's filled rows are another item's answer).

One exemplar per type, in full

Type 1 (easy, LIF5-058). An owl hears a mouse in the grass and swoops down. Which organ of the owl decided to swoop? — the brain / the heart / the stomach / the lungs. Why: The brain takes in messages from the senses and decides what the body does. The owl's ears sent a message about the mouse to its brain. So its brain decided to swoop.

Type 2 (easy, LIF5-058). A boy hears the school bell and walks to the line. Where did the message from his ears go first? — to his feet / to his heart / to his brain / to his hands. Why: Messages come in to the brain from the senses. His ears sent a message about the bell. So the message went to his brain first.

Type 3 (easy, LIF5-058). A girl is remembering the words of a song. Which organ is doing the remembering? — the lungs / the stomach / the brain / the heart. Why: Thinking and remembering happen in the brain. So her brain is doing the remembering.

Type 4 (medium, LIF5-058). A rabbit sees its hutch door open and hops out. Which of these happens second? — The rabbit's eyes see the open door. / The rabbit's legs hop out of the hutch. / The rabbit's brain decides to hop out. / The rabbit's eyes send a message to its brain.. Why: First the eyes see the open door and send a message to the brain. Then the brain takes in the message and decides to hop out. Then the brain sends a message to the legs, and the legs hop. So the brain deciding is second.

Type 5 (medium, LIF5-058). Here is a card for a fox at night, with the first box empty. What goes in the empty box? — Its ears hear a rustle in the grass. / Its brain decides to creep closer. / Its legs creep toward the sound. / Its brain sends a message to its legs.. Why: The first box is what the fox sensed, and the card says it creeps toward a sound. The ears gather sounds and send a message to the brain. So the first box is: its ears hear a rustle in the grass. (figure pp_chain_fox)

Type 6 (easy, LIF5-059). Thunder rumbles over a girl's house. Which organ gathers the sound of the thunder? — the eyes / the ears / the nose / the skin. Why: Each sensory organ gathers one kind of information. The ears gather sounds. So her ears gather the sound of the thunder.

Type 7 (easy, LIF5-059). A boy's ears gather one kind of information. Which kind is it? — what things look like / sounds / smells / tastes. Why: Each sensory organ gathers one kind of information. The ears gather sounds. So the kind his ears gather is sounds.

Type 8 (easy, LIF5-059). A girl's eyes gather what a kite looks like. Where do her eyes send that information? — to her ears / to her brain / to her heart / to her hands. Why: Each sensory organ gathers one kind of information and sends it to the brain. Her eyes gathered what the kite looks like. So they send that information to her brain.

Type 9 (medium, LIF5-059). Here is a table of organs and what each gathers, with one organ missing. Which organ goes in the empty cell? — the ears / the nose / the tongue / the skin. Why: The empty cell is beside the word sounds. The ears gather sounds. So the ears go in the empty cell. (figure pp_table_blank_ears)

Type 10 (medium, LIF5-059). A boy's nose gathers the smell of a skunk, and his brain decides to hold his breath. Which organ did the deciding? — his nose / his brain / his lungs / his mouth. Why: Each sensory organ gathers one kind of information and sends it to the brain. The nose gathered the smell; the brain takes in the message and decides. So his brain did the deciding.

Type 11 (easy, LIF5-063). Which organ covers the whole body, from the top of the head to the bottom of the feet? — the heart / the skin / the brain / the lungs. Why: The skin covers the whole body and keeps germs out. So the organ that covers the whole body is the skin.

Type 12 (easy, LIF5-063). A girl plays tag at the beach on a hot day, and sweat forms on her face. Which organ made the sweat? — her brain / her lungs / her heart / her skin. Why: When the body is hot, the skin makes sweat. So her skin made the sweat.

Type 13 (medium, LIF5-063). A boy holds a warm mug of soup in both hands. Which organ gathers the warmth of the mug? — the eyes / the ears / the nose / the skin. Why: The skin is a sensory organ: it gathers touch and warmth and sends it to the brain. So his skin gathers the warmth of the mug.

Type 14 (hard, LIF5-063). This organ covers the whole body, keeps germs out, gathers touch and warmth, and helps keep the body at the right warmth. Type the name of this organ. — typed; accept: skin, the skin, its skin, his skin, her skin, your skin, skinn, skine, the skinn. Wrong answers with their own line: hair → Hair grows out of it. The organ that covers the whole body is the skin.; brain → The brain is inside the head. The organ that covers the whole body is the skin.; bones → Bones are inside the body. The organ that covers the whole body is the skin.. Why: The skin covers the whole body and keeps germs out. It also gathers touch and warmth, and it helps keep the body at the right warmth. So the organ is the skin. Hard because: the term produced from its three jobs, nothing in view to pick from.

Every hard item's "hard because" line

• PP-41 (LIF5-058): the term produced from its whole job, nothing in view to pick from
• PP-42 (LIF5-058): the word produced for both directions of the chain, from a description of each
• PP-43 (LIF5-058): three jobs of the brain in one scene; each distractor moves one job to another body part
• PP-44 (LIF5-059): the definition applied to four organs named with no job given; the student recalls each organ's job, then applies the definition
• PP-45 (LIF5-059): the organ produced from the information it gathers, nothing in view to pick from
• PP-46 (LIF5-059): the organ produced from the information it gathers, nothing in view to pick from
• PP-47 (LIF5-059): the organ produced from the information it gathers, nothing in view to pick from
• PP-48 (LIF5-063): the term produced from its three jobs, nothing in view to pick from
• PP-49 (LIF5-063): the word produced from its description
• PP-50 (LIF5-063): two cases judged against both halves of the rule in one item
• PP-51 (LIF5-063): the bandage's job is inferred from both halves of the rule and the growth of new skin; nothing in the stem names it
• PP-52 (LIF5-063): three happenings put in cause-and-effect order: heating, sweat, cooling

v2 (8 Oct 2026, non-author review)

The review retagged the one-step definition-to-term pick (the twin of Lesson 2 (The sensory organs: what each one gathers), question 10) as medium and re-cased it on a fresh organ (a bear's ears), moving it into the LIF5-059 medium block as PP-33; the items that were PP-33 to PP-42 are now PP-34 to PP-43. Tiers now easy 20 / medium 20 / hard 12 (LIF5-058 7 / 4 / 3; LIF5-059 9 / 9 / 4; LIF5-063 4 / 7 / 5). PP-21, PP-22, PP-23, PP-24, PP-36, PP-39 and PP-43 were re-worded (see REVIEW_G5T32_2026-10-08.md); no key letter moved. The inventory and hard-because lists above are regenerated from the bank.

Adjudication (8 Oct 2026, after the two blind reads)

Both readers agreed every key except PP-43, where both read "her ears took in the message" as fair (the lessons say the ears gather and send). PP-43 now opens every option "Her ears gathered the sound" and the options differ only on where the remembering and the deciding happened; its key letter moved D → A in the source (bank keys A 10 · B 13 · C 12 · D 10). PP-21 prints the decide step and asks what happens next (the brain's message to the legs; the "legs hop with no message" wrong is a stated error, not a step). PP-33 and PR-11 lost the self-made labels (food / pumping / breathing organ) for plain wrongs. PP-44's stem no longer prints the ears' job. PP-52 is a heating → sweat → cooling chain. PP-42's accept list takes "information" and "signal" (Lesson 2 (The sensory organs: what each one gathers)'s own word). PR-01 and PR-02 carry a retrieval field and open their why "An earlier topic taught this". The ⟂ constraints above are the readers'.
