Which stage of engineering work is primarily concerned with creating new discoveries and their uses?

• A. Research
• B. Development
• C. Design
• D. Construction

Answer: (A)

The main concept here is identifying where new discoveries and their uses are created in engineering work. This stage involves exploring questions, conducting experiments, and expanding knowledge to uncover new principles, materials, or methods and to imagine how they could solve real problems. That exploratory, knowledge-building effort is what research is for, laying the groundwork for all later steps.

Once discoveries are made, development picks up to turn those ideas into workable products, processes, and systems, including prototypes and tests. Design then specifies the exact details—how the system will function, its geometry, interfaces, and constraints—before construction actually builds and implements it.
