Question

Match List-I with List-II.

List-I	List-II
A. Population B. Lifelines C. Economic data D. Building	I. Gas II. Business III. Age IV. Height

• A. A-III, B-I, C-II, D-IV
• B. A-I, B-IV, C-II, D-III
• C. A-III, B-II, C-I, D-IV
• D. A-IV, B-I, C-II, D-III

Hint:

In community mapping, population is linked with age, lifelines with services like gas, economic data with business, and buildings with height.

Answer 1

The Correct Option is A

Concept: Community mapping uses different basic units to represent elements at risk. These units help in preparing vulnerability and risk maps.

Step 1: Match population.
Population can be mapped using demographic units such as age, gender, density, and social groups. \[ A \rightarrow III \]

Step 2: Match lifelines.
Lifelines include essential services such as gas, electricity, water supply, roads, and communication systems. \[ B \rightarrow I \]

Step 3: Match economic data.
Economic data are related to business, employment, income, trade, and commercial activities. \[ C \rightarrow II \]

Step 4: Match building.
Buildings can be mapped using physical characteristics such as height, material, floor number, and structure type. \[ D \rightarrow IV \] Therefore, the correct matching is: \[ A-III,\ B-I,\ C-II,\ D-IV \]
