- AHandcarts should be barred from the lane between eight and eleven in the morning
- BThe main lane should be widened
- CThe market should be shifted to a ground outside the town
- DThe wholesale vans should be required to unload between five and eight in the morning, before the lane fills, and the handcarts left where they are
Step-by-Step Solution
The clerk's count fixes the blockage to the three hours the vans unload and shows it occurring in full on two mornings when there was not a handcart in the lane, so the handcarts are not what blocks it. Moving the unloading to the empty early hours meets the cause. Barring handcarts for those three hours removes something the count has already cleared. Widening the lane and shifting the whole market are large works undertaken against a cause that a change of unloading hours would answer for nothing.
Answer: D) The wholesale vans should be required to unload between five and eight in the morning, before the lane fills, and the handcarts left where they are
