Pedagogical Strategy & Myth-Busting Reading Comprehension
This lesson advances beyond basic categorization into critical evaluative reading. In scientific and expository writing, authors frequently contrast a popular misconception with an anatomical or biological reality. Students must identify what the author is actually explaining rather than latching onto familiar folklore.
Paragraph 4: Raccoon Eating & Food Soaking
Key: c
"Have you ever watched a raccoon eat? If you have seen one anywhere near water, you would think it was washing food... A raccoon has a small throat, and it is much easier to swallow soft food..."
✓ (c) Why raccoons wash their food [CORRECT]
Accurately states the central explanatory purpose of the passage. The author clarifies that what looks like washing is biologically a method of lubricating dry food to fit their narrow throats.
✗ (a) Eating habits of the raccoon [TOO BROAD]
A general title on eating habits would describe omnivorous foraging, catching fish, raiding crops, or eating acorns. The text focuses exclusively on the phenomenon of soaking food.
✗ (b) The cleanest animal of all [FACTUALLY MISLEADING / FOLKLORE]
The author explicitly shows that people merely assume raccoons are clean; the behavior is anatomical, not hygienic.
Paragraph 5: Porcupines & Defensive Quills
Key: c
"Are porcupines dangerous? Will they really shoot a person or an animal full of quills?... Porcupines do not 'shoot their quills'; but will use them in self-defense."
✓ (c) How porcupines protect themselves [CORRECT]
Synthesizes the whole paragraph: explains how porcupines respond when threatened (arching backs, lashing tails with barbed quills) and clarifies their purely defensive purpose.
✗ (a) Porcupines are friendly animals [TOO NARROW / MISLEADING]
Only mentions their passive temperament when undisturbed; completely misses the core topic of their barbed quill defense.
✗ (b) Porcupines shoot their quills [FACTUALLY CONTRADICTED]
The text directly refutes this myth: "Porcupines do not 'shoot their quills'; but will use them in self-defense."
Paragraph 6: Amazon Ants Social Hierarchy
Key: b
"One family of ants, known as the Amazon ants, must capture slaves to do their work. They could not live otherwise. The Amazon ants have sharp jaws which are good for fighting..."
✓ (b) Slave ants [CORRECT]
Captures the entire biological relationship: Amazon ants cannot survive without captured black slave ants, who perform all colony labors (feeding the masters, digging tunnels, building nests).
✗ (a) Amazon ants have sharp jaws [TOO NARROW]
Just one physical adaptation mentioned to explain why the masters cannot perform worker duties.
✗ (c) How ants are fed [TOO NARROW]
Feeding is only one of three essential duties performed by slave ants (along with digging and building).
