Academic Presentation #7: Handle Questions with Confidence
Handle Questions with Confidence
Listen carefully, answer the actual question, and be honest about what you know.
LESSON 07 OF 08 · READ + PRACTISEQuestions are part of the scientific conversation. You do not need an instant answer to every question. You do need to listen, understand the request, and explain the evidence fairly. Pause before replying. It is better to think briefly than to start a long answer to the wrong question.
THE IDEA IN ONE PICTURE

Clarify before answering
If you did not hear, say “Could you repeat the last part, please?” If the meaning is unclear, ask “Are you asking about the sensor accuracy or the model error?” Repeat or summarise the question when others in the room may not have heard it. Do not pretend to understand an unfamiliar term.
Give the short answer first
For example: “No, we have not tested higher temperatures yet. Our current measurements are all at room temperature.” Then add the relevant evidence or a useful next step. If a question has several parts, handle them one at a time. Ask “Does that answer your question?” when you are unsure whether your answer addressed it.
Respond to criticism calmly
A question about a weakness is not necessarily a personal attack. Say “That is a possible explanation. We would need a control experiment to separate the two effects.” If the question contains a mistake, correct it politely with the figure or method. If you do not know, say so. Label a guess as a guess; never invent a measurement to sound confident.

Turn a research claim into a useful question
This short talk explains membrane research for lithium recovery. It is not a recorded Q&A. Use the presentation as evidence for the question practice below.

What to notice
- 1:28–1:48: Notice the comparison used to explain a difficult separation problem.
- 2:29–2:38: Identify the specific process step in the energy claim.
Try it: A listener asks: “Does this mean all lithium production now uses twenty times less energy?” Practise a careful 20-second answer.
Check your viewing task
“The claim in this talk concerns a particular extraction step, not all lithium production. We would need the full method, comparison conditions, and wider process data before making that conclusion.” This is a practice response, not the speaker’s recorded answer.
Do not invent a result when answering. Separate what the presentation says from what you would need to check in the research paper.

Your turn · 2-minute practice
A listener asks, “Will your design work outdoors?” You tested only indoors. Give a useful answer without making a promise.
See a model answer or self-check
“We have not tested it outdoors. These results are from indoor tests only. Outdoor use would require tests of temperature changes and other relevant conditions.” Name the actual conditions your project would need, rather than assuming them.
