Problem: Child labour:

Small-scale artisanal mining of gold is another source of dangerous child labour in poor rural areas in certain parts of the world. This form of mining uses labour-intensive and low-tech methods. It is informal sector of the economy. Human Rights Watch group estimates that about 12 percent of global gold production comes from artisanal mines. In west Africa, in countries such as Mali - the third largest exporter of gold in Africa - between 20,000 and 40,000 children work in artisanal mining. Locally known as orpaillage, children as young as 6 years old work with their families. These children and families suffer chronic exposure to toxic chemicals including mercury, and do hazardous work such as digging shafts and working underground, pulling up, carrying and crushing the ore. The poor work practices harm the long term health of children, as well as release hundreds of tons of mercury every year into local rivers, ground water and lakes. Gold is important to the economy of Mali and Ghana. For Mali, it is the second largest earner of its export revenue. For many poor families with children, it is the primary and sometimes the only source of income.

What is another source of mining dangerous to children workers?

A: gold

Problem: Separation of church and state in the United States:

Jefferson and James Madison's conceptions of separation have long been debated. Jefferson refused to issue Proclamations of Thanksgiving sent to him by Congress during his presidency, though he did issue a Thanksgiving and Prayer proclamation as Governor of Virginia. Madison issued four religious proclamations while President, but vetoed two bills on the grounds they violated the first amendment. On the other hand, both Jefferson and Madison attended religious services at the Capitol. Years before the ratification of the Constitution, Madison contended "Because if Religion be exempt from the authority of the Society at large, still less can it be subject to that of the Legislative Body." After retiring from the presidency, Madison wrote of "total separation of the church from the state." " "Strongly guarded as is the separation between Religion & Govt in the Constitution of the United States," Madison wrote, and he declared, "practical distinction between Religion and Civil Government is essential to the purity of both, and as guaranteed by the Constitution of the United States." In a letter to Edward Livingston Madison further expanded, "We are teaching the world the great truth that Govts. do better without Kings & Nobles than with them. The merit will be doubled by the other lesson that Religion flourishes in greater purity, without than with the aid of Govt." Madison's original draft of the Bill of Rights had included provisions binding the States, as well as the Federal Government, from an establishment of religion, but the House did not pass them.[citation needed]

Problem: Dog:

Neutering reduces problems caused by hypersexuality, especially in male dogs. Spayed female dogs are less likely to develop some forms of cancer, affecting mammary glands, ovaries, and other reproductive organs. However, neutering increases the risk of urinary incontinence in female dogs, and prostate cancer in males, as well as osteosarcoma, hemangiosarcoma, cruciate ligament rupture, obesity, and diabetes mellitus in either sex.

Female dogs are less likely to develop cancer if what happens?

A: Spayed

Problem: Alfred North Whitehead:

The ultimate substantive legacy of Principia Mathematica is mixed. It is generally accepted that Kurt Godel's incompleteness theorem of 1931 definitively demonstrated that for any set of axioms and inference rules proposed to encapsulate mathematics, there would in fact be some truths of mathematics which could not be deduced from them, and hence that Principia Mathematica could never achieve its aims. However, Godel could not have come to this conclusion without Whitehead and Russell's book. In this way, Principia Mathematica's legacy might be described as its key role in disproving the possibility of achieving its own stated goals. But beyond this somewhat ironic legacy, the book popularized modern mathematical logic and drew important connections between logic, epistemology, and metaphysics.
