Problem: Lack of meaningful alternatives, such as affordable schools and quality education, according to ILO, is another major factor driving children to harmful labour. Children work because they have nothing better to do. Many communities, particularly rural areas where between 60–70% of child labour is prevalent, do not possess adequate school facilities. Even when schools are sometimes available, they are too far away, difficult to reach, unaffordable or the quality of education is so poor that parents wonder if going to school is really worth it.
Do the poor families put a value on education?

Answer: parents wonder if going to school is really worth it.


Problem: From 1950 to 2011, world population increased from 2.5 billion to 7 billion and is forecast to reach a plateau of more than 9 billion during the 21st century. Sir David King, former chief scientific adviser to the UK government, told a parliamentary inquiry: "It is self-evident that the massive growth in the human population through the 20th century has had more impact on biodiversity than any other single factor." At least until the middle of the 21st century, worldwide losses of pristine biodiverse land will probably depend much on the worldwide human birth rate.
What is the forecast plateau that the population will reach during the 21st century?

Answer: more than 9 billion


Problem: Before glaciation, mountain valleys have a characteristic "V" shape, produced by eroding water. During glaciation, these valleys are widened, deepened, and smoothed, forming a "U"-shaped glacial valley. The erosion that creates glacial valleys eliminates the spurs of earth that extend across mountain valleys, creating triangular cliffs called truncated spurs. Within glacial valleys, depressions created by plucking and abrasion can be filled by lakes, called paternoster lakes. If a glacial valley runs into a large body of water, it forms a fjord.
How is a fjord formed?

a glacial valley runs into a large body of water
