UGC NET Questions (Paper – 1)

Statement A describes how line graphs display data as connected points, often across time. Statement B is correct because line graphs are designed to show trends and changes over intervals clearly. Statement D is also true; in exams candidates often estimate values when scale markings are coarse. Statement C is false since multiple lines are precisely used to compare series, and E is false because years and months are very common on the horizontal axis for such graphs. Thus A, B and D only are correct, which matches option B.

Option A:
Option A is incomplete because it leaves out D, failing to mention the practical aspect of approximate reading from line graphs, which is typical in NET data interpretation.

Option B:
Option B is correct as it gathers the basic definition, the main use for detecting trends and the realistic need for approximation, while excluding C and E, which misrepresent the comparative and temporal use of line graphs.

Option C:
Option C is wrong because it includes E, which wrongly bans years or months on the axis, and it omits A, thereby combining an error with the omission of a central property.

Option D:
Option D is incorrect since it includes C, which claims that simultaneous comparison is impossible, when in fact it is one of the main reasons for drawing multi-line graphs.
