Answer:
Most people who live in Africa work in agriculture, mostly at the subsistence level. This means that many people are engaged in farming and herding, but they only produce enough to feed themselves and their families. For these farmers, there is not a lot left over to sell at a market, so they do not have cash to buy other things that are needed to improve their standard of living, such as clothing or electricity. As a result, most people live in poverty, often on one-to-two dollars a day. There are no social protections like welfare or food stamps. People do not live as long because they are more likely to die of disease or malnutrition.

Answer:
There were two main shortcomings with the Literary Digest's 1936 presidential poll:
- Sample bias: the magazine selected 10 million people out of three sources: telephone directories, club memberships, and magazine-suscriber lists. These sources gave the sample and middle an upper middle cass bias because in the epoch, few poor people owned telephones, were members of private clubs, or were suscribers of magazines.
- Nonresponse bias: Literary Digest wanted to survey 10 million people, but out of the 10 million people who received the poll, only 2.5 million people responded. This is called a nonresponse bias because the people who respond surveys have specific qualities different from the people who do not respond surveys.
Modern-pollsters tries to be more careful when selecting a sample: it should be representative of the population as a whole. Pollsters also have to deal with nonresponse bias, therefore, they try to send their surveys to people who are more likely to respond.
