• A. The ratio of the percentage of population falling into overweight category to the percentage of population falling into normal category has increased in 20 years.
• B. The ratio of the percentage of population falling into underweight category to the percentage of population falling into normal category has decreased in 20 years.
• C. The ratio of the percentage of population falling into obese category to the percentage of population falling into normal category has decreased in 20 years.
• D. The percentage of population falling into normal category has decreased in 20 years.

Hint:

When analyzing bar charts, focus on percentage changes over time and compare category ratios to identify trends accurately.

Answer 1

The Correct Option is C

Step 1: Interpret the data from the bar chart.
Based on the chart, the following observations can be made: The percentage of the population classified as normal decreased from 50\% in 2003 to 40\% in 2023. The percentage in the overweight category rose from 30\% in 2003 to 35\% in 2023. The obese category increased from 10\% in 2003 to 15\% in 2023. The underweight category saw a slight decline from 10\% in 2003 to 5\% in 2023. Step 2: Assess the validity of each statement.
1. Correct: The ratio of overweight to normal increased as the overweight percentage rose while the normal category declined.
2. Correct: The ratio of underweight to normal decreased due to a significant drop in underweight individuals alongside a moderate decrease in the normal category.
3. Incorrect: The ratio of obese to normal actually increased, as obesity rose from 10\% to 15\%, while normal declined from 50\% to 40\%.
4. Correct: The percentage of the normal population decreased over the given period. Final Answer: \[\boxed{{(3)}}\]
