Case D: The Birth of Skateboarding 4 Sentences
(1) Skateboarding was invented in Southern California during the 1950s by surfers who wanted a pastime when ocean waves were flat. (2) These inventive wave riders took flat wooden planks and attached steel roller-skate wheels directly to the underneath side. (3) Today, professional skateboarders perform complex aerial spins on sixty-foot mega ramps in world championships. (4) Originally called "sidewalk surfing," this new street activity let surfers practice carving turns and balancing maneuvers on solid pavement.
1. Underline the off-topic sentence above. Which sentence is it? Sentence: [ _____ ]
2. Detective Analysis: Why might a reader mistakenly assume Sentence (3) belongs here? Why must an editor still cut it?

The Editor's Desk • Rewrite & Polish
Identify the subtle detour and produce a polished final draft.
Draft Passage: The Monarch Migration
(1) Every autumn, millions of monarch butterflies embark on an epic two-thousand-mile flight from Canada down to mountainous forests in central Mexico. (2) To survive the exhausting voyage, monarchs catch thermal air currents to glide smoothly and conserve their energy. (3) During summer breeding, female monarchs deposit single pinpoint-sized eggs strictly on the undersides of milkweed leaves. (4) Once they reach their winter sanctuary, monarchs gather in dense clusters on oyamel fir branches to stay shielded from mountain freezes. (5) This awe-inspiring journey is celebrated as one of the animal kingdom's greatest navigation wonders.
Editor's Task: Draw a line through the subtle intruder sentence in the draft above. Then, neatly rewrite the revised 4-sentence paragraph below so every sentence focuses strictly on the migration journey.

Student Conference Question
"Yes, this sentence mentions skateboarding—but is it about how skateboarding began in the 1950s, or something else entirely?"
