Problem: Nigeria:

Waste management including sewage treatment, the linked processes of deforestation and soil degradation, and climate change or global warming are the major environmental problems in Nigeria. Waste management presents problems in a mega city like Lagos and other major Nigerian cities which are linked with economic development, population growth and the inability of municipal councils to manage the resulting rise in industrial and domestic waste. This huge waste management problem is also attributable to unsustainable environmental management lifestyles of Kubwa Community in the Federal Capital Territory, where there are habits of indiscriminate disposal of waste, dumping of waste along or into the canals, sewerage systems that are channels for water flows, etc.

What Nigerian community has the worst unsustainable waste management?
---
A: Kubwa Community

One of the most important developments that the Enlightenment era brought to the discipline of science was its popularization. An increasingly literate population seeking knowledge and education in both the arts and the sciences drove the expansion of print culture and the dissemination of scientific learning. The new literate population was due to a high rise in the availability of food. This enabled many people to rise out of poverty, and instead of paying more for food, they had money for education. Popularization was generally part of an overarching Enlightenment ideal that endeavoured "to make information available to the greatest number of people." As public interest in natural philosophy grew during the 18th century, public lecture courses and the publication of popular texts opened up new roads to money and fame for amateurs and scientists who remained on the periphery of universities and academies. More formal works included explanations of scientific theories for individuals lacking the educational background to comprehend the original scientific text. Sir Isaac Newton's celebrated Philosophiae Naturalis Principia Mathematica was published in Latin and remained inaccessible to readers without education in the classics until Enlightenment writers began to translate and analyze the text in the vernacular.
Instead of paying more for food, on what did people spend their money?
A: education

Presbyterianism is the largest Protestant denomination in Northern Ireland and the second largest on the island of Ireland (after the Anglican Church of Ireland),[citation needed] and was brought by Scottish plantation settlers to Ulster who had been strongly encouraged to emigrate by James VI of Scotland, later James I of England. An estimated 100,000 Scottish Presbyterians moved to the northern counties of Ireland between 1607 and the Battle of the Boyne in 1690.[citation needed] The Presbytery of Ulster was formed in 1642 separately from the established Anglican Church. Presbyterians, along with Roman Catholics in Ulster and the rest of Ireland, suffered under the discriminatory Penal Laws until they were revoked in the early 19th century. Presbyterianism is represented in Ireland by the Presbyterian Church in Ireland, the Free Presbyterian Church of Ulster, the Non-subscribing Presbyterian Church of Ireland, the Reformed Presbyterian Church of Ireland and the Evangelical Presbyterian Church.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How many Scottie Presbyterians moved to the northern counties in Ireland?
Ah, so..
100,000
