Final answer:
The researcher's goal to use advertising to encourage smoking cessation represents applied research, aimed at addressing a specific, practical issue with real-world applications.
Step-by-step explanation:
The goal of research reflected in a situation where the researcher wants to address a practical problem, such as presenting strategies to use advertisements to encourage people to stop smoking, is applied research. Applied research is a methodology used to solve a specific, practical issue affecting an individual or group. This type of research focuses on finding a solution to a real-world problem, and it differs from basic research, which is aimed at gaining knowledge for its own sake and understanding the fundamental principles of phenomena.
