Solution

Solution Steps

Step 1: Identify the data points for motor gasoline

1960: 4.07 million barrels per day
1970: 4.81 million barrels per day
1980: 5.64 million barrels per day
1990: 6.62 million barrels per day
2000: 8.22 million barrels per day

Step 2: Calculate the increase for each 10-year period

1960 to 1970: 4.81 - 4.07 = 0.74 million barrels per day
1970 to 1980: 5.64 - 4.81 = 0.83 million barrels per day
1980 to 1990: 6.62 - 5.64 = 0.98 million barrels per day
1990 to 2000: 8.22 - 6.62 = 1.60 million barrels per day

Step 3: Determine the greatest increase

The greatest increase is from 1990 to 2000 with an increase of 1.60 million barrels per day.

Final Answer

The increase in supply of motor gasoline was the greatest during the period from 1990 to 2000.
