Question No. 1.Option C

Question No. 2. Option A

Question No. 3. Option D

Question No. 4. Option D

Question No. 5. Option B


The first questions demands the year when the law-breaking problem erupted in the country. It is represented by the yellow bars in the diagram. A sudden increase in the crime rate can be seen in the year 2008 when the crime rate elevated above five.

Next question is based on the population trend of the country. The given multiple bar diagram shows the birth rate of the country using blue bars and purple bars represent the death rate. It can be seen that the birth rate is going high with the passing years and the death rate is slow as compare to it. This indicates a rise in the population level of the country.

Third question requires the year when the company seems to have faced some severe disease. The death rate of the country in the year 2009 appears to be substantially high, which indicates a possibility that there might be some severe disease spread in the country during that year.

Question number four requires the student to indentify the component which is affected by the economic growth of the country. Out of the four components of the multiple bar diagram, the one which is directly affected by the economy is the income level of the people of country.

The answer to the last question is the simplest to identify, which is option B. It reflects yearly analysis of the country population, income and crime.
