Doing literarure review from broader topic to a focal point is the- Literature search Convergent search Objective search Both b and c

Break Down the Problem

1. Identify the methodology used in conducting literature reviews.
2. Understand the characteristics of each type of search mentioned: convergent search, objective search, and their combination.

Relevant Concepts

• Convergent Search: Involves narrowing down from a broad topic to a specific area of study.
• Objective Search: Focuses on finding literature that meets specific criteria or objectives.

Analysis and Detail

1. Literature Search: This generally refers to the process of searching through existing literature to gather relevant information on a specific topic.
2. Convergent Search: It typically starts with a wide scope and gradually houses in on a precise niche, which seems to fit the description provided.
3. Objective Search: This approach is more targeted, intending to fulfill predefined questions, criteria, or objectives—this might also refer to a focused review process.

Verify and Summarize

The question asks about a specific approach that involves transitioning from a broader topic to a focal point. Since both convergent and objective searches can encapsulate this process, “Both b and c” (where b is convergent search and c is objective search) aptly defines the situation.

Final Answer

The correct answer is Both b and c.
