For a given size of bucket, the ideal output of a dragline will be least in
A. Moist loam
B. Sand and gravel
C. Good common earth
D. Wet sticky clay
Answer: Option D
Solution (By Examveda Team)
Let's look at each option:Option A: Moist loam: Loam is generally a good soil type for digging, especially when moist. So, output would be relatively good.
Option B: Sand and gravel: Sand and gravel are loose materials, easy to dig. Output would be high.
Option C: Good common earth: This is also generally good for digging, so output would be decent.
Option D: Wet sticky clay: Wet sticky clay is the most difficult material to dig and load. It sticks to the bucket, making it hard to empty and reducing the amount of material that can be moved per cycle.
Therefore, the answer is Option D: Wet sticky clay because it offers the least ideal digging conditions, leading to the lowest output.

Answer is Wet sticky clay,
Why?
Because wet sticky clay:
Sticks to the bucket, reducing the fill efficiency.
Takes longer to empty the bucket while dumping.
Increases the overall cycle time.
Makes digging difficult due to suction and adhesion.
So — output is least in wet sticky clay.
