- AThe staff visited fewer homes in each year than in the year before
- BThe number of homes found with an uncovered container rose in each year, while the share of visited homes in which one was found fell in each year
- CBy year 3 fewer than a fifth of the homes visited had an uncovered container
- DIn year 3 the staff visited every home in the district
Step-by-Step Solution
The counts run 1,200, 1,250 and 1,320, which rises, while the shares run 30, 25 and 22 per cent, which falls — the two move opposite ways because the number of visits grew faster. Visits rose rather than fell; 22 per cent in year 3 is above a fifth, not below it; and nothing in the record says how many homes the district holds.
Answer: B) The number of homes found with an uncovered container rose in each year, while the share of visited homes in which one was found fell in each year
