Problem: Critics of the modern concept of the "separation of church and state" argue that it is untethered to anything in the text of the constitution and is contrary to the conception of the phrase as the Founding Fathers understood it. Philip Hamburger, Columbia Law school professor and prominent critic of the modern understanding of the concept, maintains that the modern concept, which deviates from the constitutional establishment clause jurisprudence, is rooted in American anti-Catholicism and Nativism.[citation needed] Briefs before the Supreme Court, including by the U.S. government, have argued that some state constitutional amendments relating to the modern conception of separation of church and state (Blaine Amendments) were motivated by and intended to enact anti-Catholicism.
What are state constitutional amendments relating to separation of church and state known as?
The answer is the following: Blaine Amendments

Problem: Solar distillation can be used to make saline or brackish water potable. The first recorded instance of this was by 16th-century Arab alchemists. A large-scale solar distillation project was first constructed in 1872 in the Chilean mining town of Las Salinas. The plant, which had solar collection area of 4,700 m2 (51,000 sq ft), could produce up to 22,700 L (5,000 imp gal; 6,000 US gal) per day and operate for 40 years. Individual still designs include single-slope, double-slope (or greenhouse type), vertical, conical, inverted absorber, multi-wick, and multiple effect. These stills can operate in passive, active, or hybrid modes. Double-slope stills are the most economical for decentralized domestic purposes, while active multiple effect units are more suitable for large-scale applications.
When was the first large solar distillation plant created?
The answer is the following: 1872

Problem: Agricultural diversity can also be divided by whether it is 'planned' diversity or 'associated' diversity. This is a functional classification that we impose and not an intrinsic feature of life or diversity. Planned diversity includes the crops which a farmer has encouraged, planted or raised (e.g.: crops, covers, symbionts and livestock, among others), which can be contrasted with the associated diversity that arrives among the crops, uninvited (e.g.: herbivores, weed species and pathogens, among others).
What are two types of Agricultural diversity?
The answer is the following: 'planned' diversity or 'associated' diversity

Problem: Demand in Europe for Chinese goods such as silk, tea, and ceramics could only be met if European companies funneled their limited supplies of silver into China. In the late 1700s, the governments of Britain and France were deeply concerned about the imbalance of trade and the drain of silver. To meet the growing Chinese demand for opium, the British East India Company greatly expanded its production in Bengal. Since China's economy was essentially self-sufficient, the country had little need to import goods or raw materials from the Europeans, so the usual way of payment was through silver. The Daoguang Emperor, concerned both over the outflow of silver and the damage that opium smoking was causing to his subjects, ordered Lin Zexu to end the opium trade. Lin confiscated the stocks of opium without compensation in 1839, leading Britain to send a military expedition the following year.
What did the Chinese want in return?
The answer is the following:
silver
