THE "I.D.E.A.S." DETECTIVE STRATEGY Status: active investigation
I
INFERENCE (Read between the lines & use schema)
"The timid kitten hid behind the dusty couch and trembled whenever someone walked past."
🔍 Clues: "hid" + "trembled" = the kitten is likely scared, shy, or fearful.
D
DEFINITION (The meaning is written directly)
"The forest canopy, which is the high, leafy roof formed by the treetops, blocked the sun."
🔍 Clues: The words "which is" signal the direct meaning of canopy.
E
EXAMPLE (An author lists items of the same type)
"The farm harvested sweet citrus fruits, including juicy oranges, lemons, and sour limes."
🔍 Clues: "including juicy oranges, lemons..." shows that citrus is a fruit group.
A
ANTONYM (Look for opposite meanings or contrast words)
"While Clara was incredibly garrulous, her brother was extremely quiet and shy."
🔍 Clues: The contrast word "While" and antonyms "quiet and shy" reveal garrulous means talkative.
S
SYNONYM (A similar word is provided nearby)
"The tired hiker felt fatigued, exhausted after climbing the steep mountain trail."
🔍 Clues: "tired" and the close synonym "exhausted" reveal the meaning of fatigued.

"The timid kitten hid behind the dusty couch and trembled whenever someone walked past."
🔎 Detective Deduction: Since the kitten hid and trembled, our schema tells us it is terrified, shy, or fearful.

Antonym Strategy
"While Clara was extremely garrulous, her brother was very quiet and rarely spoke."
🔎 Detective Deduction: The word "While" sets up a contrast. The brother is quiet and rarely speaks, so Clara is talkative!
