N-Level Technical and Vocational Skills 3 — Questions and Answers
Question 1: What is the difference between hardwood and softwood?
- Hardwood is always harder than softwood
- Hardwood comes from deciduous (broad-leaved) trees; softwood comes from coniferous (needle-leaved) trees — though not always harder in texture (Correct answer)
- Softwood comes from deciduous trees
- There is no difference
Correct answer: Hardwood comes from deciduous (broad-leaved) trees; softwood comes from coniferous (needle-leaved) trees — though not always harder in texture
Hardwood (oak, teak, mahogany) comes from deciduous trees with broad leaves. Softwood (pine, cedar, spruce) comes from coniferous trees. The terms refer to tree type, not necessarily hardness.
Question 2: In food technology, what does 'food hygiene' include?
- Only washing hands
- Maintaining cleanliness of hands, tools, surfaces, and food itself to prevent contamination and foodborne illness (Correct answer)
- Making food look attractive
- Storing food in any available space
Correct answer: Maintaining cleanliness of hands, tools, surfaces, and food itself to prevent contamination and foodborne illness
Food hygiene involves: washing hands, sanitising surfaces and utensils, proper food storage (correct temperatures), avoiding cross-contamination, and maintaining personal hygiene when handling food.
Question 3: What is the purpose of a 'design brief' in design and technology?
- A finished product
- A document that outlines the design problem, requirements, constraints, and context that the designer must address (Correct answer)
- A technical drawing
- A list of materials
Correct answer: A document that outlines the design problem, requirements, constraints, and context that the designer must address
A design brief sets out what needs to be designed, for whom, why, and any constraints (budget, materials, size). It guides the entire design process from start to finish.
Question 4: What does 'ergonomics' mean in product design?
- Making products look attractive
- Designing products and environments to fit the user's physical and cognitive needs for comfort, efficiency, and safety (Correct answer)
- Making products cheap to manufacture
- Designing for durability only
Correct answer: Designing products and environments to fit the user's physical and cognitive needs for comfort, efficiency, and safety
Ergonomics is the science of designing products, systems, and environments to fit users' physical and mental characteristics, reducing discomfort, injury, and inefficiency — e.g., an ergonomic chair supports posture.
Question 5: What safety precaution should you take when soldering in electronics?
- No precautions needed
- Work in a well-ventilated area, wear safety glasses, use a soldering stand, and wash hands after — solder fumes and lead are hazardous (Correct answer)
- Only wear gloves
- Solder near open windows only
Correct answer: Work in a well-ventilated area, wear safety glasses, use a soldering stand, and wash hands after — solder fumes and lead are hazardous
Soldering produces hazardous fumes from flux — ventilation is essential. Safety glasses protect from splashes. A soldering iron stand prevents burns. Lead in solder is toxic — wash hands thoroughly after work.
Question 6: What is 'sustainable design'?
- Designing things that are fashionable
- Designing products that minimise environmental impact throughout their lifecycle — using renewable materials, reducing energy use, and enabling recycling (Correct answer)
- Making products that last only one year
- Using only plastic materials
Correct answer: Designing products that minimise environmental impact throughout their lifecycle — using renewable materials, reducing energy use, and enabling recycling
Sustainable design considers the environmental impact at every stage: material sourcing (renewable/recycled), manufacturing (low energy), use (efficient), and end-of-life (recyclable/biodegradable) — minimising ecological harm.
