Drill 87: Saying One Main Idea With Real Support, Out Loud
Say a short spoken passage with one clear main-idea sentence and two to three genuinely supporting sentences, live under a timer — the spoken mirror of Lesson 87's information-hierarchy skill, and the final speaking drill in this course so far.
Learning Objectives
By the end of this drill, you should be able to:
- Say one sentence that states a real main idea, not just a topic
- Say two to three supporting sentences that genuinely develop that idea, live, with no drafting first
- Apply the removal test in real time to judge which of your own sentences actually earn their place
Introduction
Lesson 87 — the final lesson in this course's reading track — taught you to sort a paragraph's sentences into a hierarchy: main idea, real support, and mere detail. This drill, the last speaking drill in the course so far, makes you build that hierarchy live, out loud, with no time to plan which sentence is which before you start speaking.
Shadow the Model
Automating berth scheduling only pays off in high-volume ports. In busy ports, the system had enough bookings to optimize assignments and cut turnaround time by nearly a third. In smaller ports, there simply weren't enough vessels scheduled for the algorithm to find any real gain.
Notice how the first sentence carries the whole point, and the two "In ___ ports" sentences that follow are doing real supporting work — remove either one mentally, and the claim gets weaker, not just shorter.
Your Turn
Your Turn
Pick a process, technology, or policy you know well. When the timer starts, say one sentence stating your main idea — not just the topic — followed by two or three spoken sentences that genuinely support it, live, with no drafting first.
Speak now — main idea first, then genuine support
Record Yourself
Record your main idea and supporting sentences, then compare against the model answer below.

There's no single correct topic — what matters is the structure. One natural version: "A new scheduling system only reduces missed shifts when staff are trained before rollout. Without that training, employees revert to the old paper process the moment something unusual happens. And when the system doesn't integrate cleanly with payroll, managers stop trusting its numbers within a few weeks." Check that each of your own supporting sentences would genuinely weaken your point if removed — not just add a loosely related fact.

Self-Check
Self-Check
- Did your first sentence state a real main idea, not just the topic?
- Would each supporting sentence genuinely weaken your point if removed, rather than just adding a related fact?
- Did you speak immediately, without a long pause to plan the structure first?
This is the final speaking drill in the course so far — there is no Speaking 88 yet. Keep running the removal test on your own live speech outside these lessons; the habit doesn't stop mattering just because the numbered drills do.
