Question 1

Assertion (A): In the border strip method of irrigation, the size of the strip depends on soil characteristics, slope of the land and discharge.
Reason (R): Border strip method is a controlled type of surface irrigation method.

• ABoth A and R are true and R is the correct explanation of A
• Bboth A and R are true but R is not a correct explanation of A
• CA is true but R is false
• DA is false but R is true

Question 2

Assertion (A): The duty of water decrease as the point of its measurement moves towards the field of application.
Reason (R): Duty depends on soil characteristics.

• ABoth A and R are true and R is the correct explanation of A
• Bboth A and R are true but R is not a correct explanation of A
• CA is true but R is false
• DA is false but R is true

Question 3

Assertion (A): The BOD in the removed at a very fast rate immediately after sewage is discharged into a river.
Reason (R): A part of the BOD in the sewage is due to Settleable organic matter therein.

Question 4

Assertion (A) : The principle of superposition is valid whenever the strain or stress to be obtained is directly proportional to the applied loads.
Reason (R) : Strain energy depends on the product of stress and strain.
