Directions:
Each of the next fourteen (14) items consists of two statements, one labeled as the ‘Assertion (A)’ and the other as ‘Reason (R)’. You are to examine these two statements carefully and select the answers to these items using the codes given below:
Codes:
(A) Both A and R are individually true and R is the correct explanation of A
(B) Both A and R are individually true but R is not the correct explanation of A
(C) A is true but R is false
(D) A is false but R is true
Assertion (A): A major shortcoming of a fire-tube boiler is that the maximum size of the unit and the maximum operating pressure are limited.
Reason (R): Both large diameters and high pressures lead to prohibitively thick shells resulting in very high cost.
