The country in which Joseph is living is a least developed country (LDC), also often referred to as a ''third world country''. This type of countries are the countries that are at the bottom in pretty much every parameter used for measuring the quality of the human life. The government and the public institutions are corrupt, and also available for only certain people, the infrastructure is terrible, the industry undeveloped, the economy in dire condition, education is of very low quality...
These types of countries though are the ones that have the highest fertility rates, often the average being between 6 and 8 children per woman. Unfortunately, because of the bad conditions lot of those children die as infants or in the early childhood, on top of that the life expectancy is very low, usually in the range between 40 and 50 years of age.
The cholodny-went model was proposed in 1927. This model explains the capability of the shoots to grow in the direction of the sunlight whereas the capability of the roots to grow downwards. The hypothesis suggested that both these directional growth occurred due to the asymmetrical distribution of the plant hormone, auxin. This model has been modified a number of times by other scientists but its general concept is accepted by most of the researchers.
