ENGAGE
Would You Be Convinced?
Imagine that a student is speaking at a Doha community meeting. The student wants more shaded water-refill points along a popular walking route. The idea may sound sensible, but a convincing argument needs more than confidence. As you listen, you must separate the main claim from its reasons and evidence. You must also notice exaggeration, bias or evidence that points in another direction. In this lesson, you will evaluate an original speech, organise listening notes and form a respectful question that tests the speaker’s reasoning.
Think about it
- Can a sensible claim still be poorly supported?
- What makes evidence trustworthy?

Listen Closely: Shaded Refill Points
Original speech transcript
Listen as someone reads this speech aloud, or record yourself reading it and play it back once. Good afternoon. I believe the Doha Corniche needs more shaded water-refill points. Walking beside the sea should help people stay active, but visitors may become uncomfortable in the heat. Of course, nothing says “healthy walk” like carrying a bottle that has become as warm as the pavement. In a survey at Education City, 84 out of 120 students said they would refill their bottles more often if the machines were shaded. A volunteer group also counted 63 empty plastic bottles near three Corniche bins during a two-hour period.
City information shows that seven refill points already serve the route. During one cool morning, volunteers saw queues at only two of them. However, that does not weaken my argument; it clearly proves that the other five are too difficult to find. Every visitor would use the new points, so they would completely solve the problem of discarded bottles. I therefore ask the community to install additional shaded points with clear signs. This would give walkers easier access to water and could reduce the number of single-use bottles left behind.
Listening focus
Note what the speaker claims, why the speaker believes it, and which details genuinely support the conclusion.
Think about it
- What is the speaker’s main claim?
- Which two pieces of numerical evidence does the speaker provide?
- Which statement is exaggerated or unsupported?
EXPLAIN
How to Evaluate a Speaker’s Argument
1. Separate the parts of the argument
| Part | Question to ask | Example from the speech |
|---|---|---|
| Claim | What does the speaker want me to accept? | The Corniche needs more shaded water-refill points. |
| Reason | Why does the speaker think this? | Shade and clear signs could make refilling easier. |
| Evidence | What information supports the reason? | 84 out of 120 surveyed students preferred shaded machines. |
Strong evidence must be relevant, sufficient and credible. Relevant evidence connects directly to the claim. Sufficient evidence provides enough information to justify the conclusion. Credible evidence comes from a dependable source or a clear method. The Education City survey is relevant to student preferences, but it may not represent every Corniche visitor. The bottle count is useful, but it does not prove why the bottles were discarded.
Unsupported does not mean automatically false
The claim that every visitor would use the new points may be possible, but the speaker gives no evidence that all visitors would behave in this way. You should label it unsupported rather than simply false.
Watch for language that influences you without adding proof. The line about a bottle becoming “as warm as the pavement” uses irony: the speaker humorously contrasts a healthy walk with an unpleasant experience. The words “clearly”, “every” and “completely” create certainty, but certainty of tone is not evidence. The speaker also shows bias by interpreting the lack of queues only as proof that points are difficult to find.
Conflicting evidence deserves attention. The speaker says more points are needed, yet city information reports that seven already exist and volunteers observed no queues at five. There may be reasonable explanations, such as cool weather, poor signs or inconvenient locations, but these explanations require evidence. A careful listener acknowledges both sides instead of ignoring inconvenient information.
- Use a three-column note frame: claim, reasons and evidence.
- Mark unsupported statements with a question mark.
- Write a probing question that requests missing evidence or tests an assumption.
- Keep your tone respectful: “What evidence suggests…?” or “How do you account for…?”
- Build on the speaker’s idea before challenging it: “Your survey suggests shade matters. How representative was the sample?”
A strong probing question
Ask: “How do you know that extra refill points, rather than clearer signs for the existing seven, would reduce discarded bottles?” This targets the speaker’s reasoning and conflicting evidence.
MYP_PRACTICE
Create an Argument Audit
Return to the speech and audit its argument. Your notes should distinguish what the speaker says from how well it is supported. Finish by writing one respectful follow-up question that asks for missing evidence, examines a possible bias or addresses the conflicting information about the seven existing refill points.
- Listen to or read the speech once without stopping. Write the main claim in one sentence.
- Listen or read again. Record at least two reasons and two pieces of evidence.
- Place a question mark beside one unsupported or exaggerated statement.
- Explain in one or two sentences why that statement lacks sufficient support.
- Write one probing follow-up question using a respectful question frame.
