Answer 1

The largest steep increase was from 1965 to 1966, while the second largest was from 1967 to 1968

Explanation:

A) 1965 to 1966; number of accidents increased from 250 to 320.

Percentage increase = (320 - 250)/250 × 100% = 28%

B) 1967 to 1968; number of accidents increased from 300 to 370.

Percentage increase = (370 - 300)/300 × 100% = 23.33%

C) 1968 to 1969; number of accidents increased from 370 to 380.

Percentage increase = (380 - 370)/370 × 100% = 2.7%

D) 1969 to 1970; number of accidents increased from 380 to 410.

Percentage increase = (410 - 380)/380 × 100% = 7.89%

Thus;

The largest steep increase was from 1965 to 1966, while the second largest was from 1967 to 1968
