Explanation:

Question 5

• Option a: Joinery is about woodwork joints, not metals.
• Option b: Metallurgy deals with metal properties, production, and purification, matching the definition.
• Option c: Welding is a joining process, not about metal properties/purification.
• Option d: Arc - Welding is a type of welding, not about metal science broadly.

• Option a: Joinery is for wood components, not fusing parts with heat/pressure.
• Option b: Metallurgy is about metal science, not a joining process.
• Option c: Welding is the process of fusing parts with heat/pressure (or both) to form a joint as they cool, matching the definition.
• Option d: Arc - Welding is a specific welding method, not the general process.

• Option a: Joinery refers to the wooden components of a building (stairs, doors, frames, etc.) collectively, matching the definition.
• Option b: Metallurgy is about metals, not wood components.
• Option c: Welding is for joining metals, not related to wood.
• Option d: Arc - Welding is a welding type, not about wood.

Answer:

b. Metallurgy
