Question 1:B

Question 2:C

Test analysis:

Question 1: The age composition of the world population should be 15-65 years old, with the largest proportion.

Question 2: The population burden coefficient should be the proportion of children and the elderly in the labor force. That is, from the perspective of the proportion of population aged 15-65, the greater the proportion of this age group, the smaller the proportion of children and the elderly, and the smaller the proportion of population aged 15-65, the greater the proportion of children and the elderly, that is, the greater the population burden. Looking at the map, we can see that the population burden coefficient first increases and then decreases.

Comments: This question is generally difficult. Students only need to master the general characteristics of population age ratio and judge the change of population burden coefficient in combination with the change of labor ratio.
