Her brother from Port Adelaide

According to the writer, people in poor countries have a lot of children mainly because

1. 
   they rely on them for support during their old age
   
2. 
   they aren't yet prepared for family planning due to their religious beliefs
   
3. 
   they usually become involved with farming, which makes it easier for them to be fed
   
4. 
   methods of family planning are not being satisfactorily practiced in those countries
   
5. 
   they receive government support for every child
   

2. 
   The writer points out that, before deciding upon family planning
   

1. 
   governments of poor countries should increase the amount of old age pensions
   
2. 
   developed countries should help developing ones to improve their standards of living
   
3. 
   governments of developing countries must forbid parents to use child labor on farms
   
4. 
   people in poor countries want to be sure of their future
   
5. 
   people in poor countries must be educated by social services, being clearly shown the advantages of having fewer children
   

3. 
   We can conclude from the writer's statements that birth rates in developed countries
   

1. 
   should be higher so that the population can meet the demand for manpower
   
2. 
   can't be reduced without strict family planning
   
3. 
   decreased as standards of living increased
   
4. 
   will go on increasing unless people change their attitudes radically
   
5. 
   are now keeping pace with economic growth
