To determine the correct conclusion about the oil industry in Nigeria based on the given data, we need to closely examine the percentages of government revenue from oil for each listed year. Here's the step-by-step analysis:
1. List of percentages of government revenue from oil for each year:
- 1967: 18.26%
- 1971: 25.99%
- 1975: 80.81%
- 1979: 66.30%
- 1983: 67.00%
- 1987: 75.80%
- 1990: 97.24%
2. Identify the key trends and compare the percentages across different years:
- From 1967 to 1975, there is a general increase in the percentage of revenue from oil: 18.26% to 80.81%.
- From 1975 to 1979, there is a noticeable decrease from 80.81% to 66.30%.
- From 1979 to 1983, the percentage remains somewhat stable, rising slightly to 67.00%.
- From 1983 to 1987, the percentage increases to 75.80%.
- From 1987 to 1990, the percentage dramatically increases to 97.24%.
3. Evaluation of each conclusion statement:
- "Nigeria was generating less revenue from oil in 1987 compared to previous years."
- This statement is incorrect. The percentage in 1987 (75.80%) is more compared to 1979 (66.30%) and 1983 (67.00%), suggesting an increase, not a decrease.
- "Nigeria was generating greater revenue from oil in 1990 compared to previous years."
- This statement is correct. In 1990, the percentage of revenue from oil was 97.24%, which is higher than in any previous year.
- "Nigeria's oil revenue peaked during 1975."
- This statement is incorrect. Although there was a significant percentage in 1975 (80.81%), the highest percentage was in 1990 (97.24%).
- "Nigeria's oil revenue decreased during 1987."
- This statement is also incorrect. The percentage in 1987 (75.80%) increased compared to 1983 (67.00%).
Conclusion:
Based on the percentages of total government revenue from oil given for the years 1967 through 1990, the correct conclusion is:
- "Nigeria was generating greater revenue from oil in 1990 compared to previous years."
