UGCNET Questions

A literature review enables the researcher to become familiar with what has already been done on a topic. By critically analyzing previous findings, the researcher can see what is known, where inconsistencies exist and what remains unexplored. This helps in sharpening the research problem, formulating appropriate objectives and avoiding unnecessary duplication.

Option A:
Option A suggests avoiding citations, which undermines scholarly honesty and disconnects the study from existing knowledge.

Option B:
Option B is correct as it highlights the three central functions: understanding existing knowledge, identifying gaps and refining the problem. These steps enhance relevance and originality of the research.

Option C:
Option C treats review as a mere way to increase length, ignoring its analytical and conceptual role in building a strong foundation for the study.

Option D:
Option D implies that literature review substitutes for methodology, which is incorrect. Methodology must still be explicitly designed and justified after reviewing literature.

A review of literature helps the researcher become familiar with what has already been studied in the chosen area. By synthesizing previous findings, the researcher can identify gaps, inconsistencies or new angles that need exploration. This process leads to more precise formulation of the research problem, objectives and hypothesis. It also helps in selecting appropriate methods and avoiding unnecessary duplication.

Option A:
Option A treats references as mere decoration, which undermines the intellectual purpose of literature review. Listing sources without critical analysis does not strengthen the study.

Option B:
Option B rightly emphasizes comprehension of past work, gap identification and problem refinement. These are widely recognized as central reasons for conducting a thorough literature review in any serious research project.

Option C:
Option C claims that literature review prevents development of theory, which is the opposite of its function. Engaging with existing theories often supports the development or modification of conceptual frameworks.

Option D:
Option D focuses on thesis length rather than content quality. Adding literature merely to increase pages has no methodological justification.
