Problem: Pope Paul VI:

The reaction to the encyclical's continued prohibitions of artificial birth control was very mixed. In Italy, Spain, Portugal and Poland, the encyclical was welcomed. In Latin America, much support developed for the Pope and his encyclical. As World Bank President Robert McNamara declared at the 1968 Annual Meeting of the International Monetary Fund and the World Bank Group that countries permitting birth control practices would get preferential access to resources, doctors in La Paz, Bolivia called it insulting that money should be exchanged for the conscience of a Catholic nation. In Colombia, Cardinal archbishop Anibal Munoz Duque declared, if American conditionality undermines Papal teachings, we prefer not to receive one cent. The Senate of Bolivia passed a resolution stating that Humanae vitae could be discussed in its implications for individual consciences, but was of greatest significance because the papal document defended the rights of developing nations to determine their own population policies. The Jesuit Journal Sic dedicated one edition to the encyclical with supportive contributions.

Problem: Software testing:

Destructive testing attempts to cause the software or a sub-system to fail. It verifies that the software functions properly even when it receives invalid or unexpected inputs, thereby establishing the robustness of input validation and error-management routines.[citation needed] Software fault injection, in the form of fuzzing, is an example of failure testing. Various commercial non-functional testing tools are linked from the software fault injection page; there are also numerous open-source and free software tools available that perform destructive testing.

There are very few open-source and free tools that do what?

A: unanswerable

Problem: Affirmative action in the United States:

FDR's New Deal programs often contained equal opportunity clauses stating "no discrimination shall be made on account of race, color or creed",:11 but the true forerunner to affirmative action was the Interior Secretary of the time, Harold L. Ickes. Ickes prohibited discrimination in hiring for Public Works Administration funded projects and oversaw not only the institution of a quota system, where contractors were required to employ a fixed percentage of Black workers, by Robert C. Weaver and Clark Foreman,:12 but also the equal pay of women proposed by Harry Hopkins.:14FDR's largest contribution to affirmative action, however, lay in his Executive Order 8802 which prohibited discrimination in the defense industry or government.:22 The executive order promoted the idea that if taxpayer funds were accepted through a government contract, then all taxpayers should have an equal opportunity to work through the contractor.:234 To enforce this idea, Roosevelt created the Fair Employment Practices Committee (FEPC) with the power to investigate hiring practices by government contractors.:22

The first introduction of a quota system mandated that contractors can't do what?

A: unanswerable

Problem: Chihuahua (state):

The officials in Mexico City reduced the price of corn from six cents to two cents a pound. The northern portion of the state continued to decline economically which led to another revolt led by G. Casavantes in August 1879; Governor Trias was accused of misappropriation of funds and inefficient administration of the state. Casavantes took the state capital and occupied it briefly; he was also successful in forcing Governor Trias to exile. Shortly afterwards, the federal government sent an entourage led by Trevino; Casavantes was immediately ordered to resign his position. Casavantes declared political victory as he was able to publicly accuse and depose Governor Trias. At the same time the states of Durango and Coahuila had a military confrontation over territorial claims and water rights; this altercation between the state required additional federal troops to stabilize the area. Later a dispute ensued again among the states of Coahuila, Durango, and Chihuahua over the mountain range area known as Sierra Mojada, when large deposits of gold ore was discovered. The state of Chihuahua officially submitted a declaration of protest in May 1880 that shortly after was amicably settled. Despite the difficulties at the beginning, Diaz was able to secure and stabilize the state, which earned the confidence and support of the people.

Who led the revolt for the northern portion of the state?
