Problem: Hunting:

A variety of industries benefit from hunting and support hunting on economic grounds. In Tanzania, it is estimated that a safari hunter spends fifty to one hundred times that of the average ecotourist. While the average photo tourist may seek luxury accommodation, the average safari hunter generally stays in tented camps. Safari hunters are also more likely to use remote areas, uninviting to the typical ecotourist. Advocates argue that these hunters allow for anti-poaching activities and revenue for local communities.[citation needed]

Where does the typical safari hunter hang his hat at night?
---
A: in tented camps

Problem: Some types of residential elevators do not use a traditional elevator shaft, machine room, and elevator hoistway. This allows an elevator to be installed where a traditional elevator may not fit, and simplifies installation. The ASME board first approved machine-room-less systems in a revision of the ASME A17.1 in 2007. Machine-room-less elevators have been available commercially since the mid 1990s, however cost and overall size prevented their adoption to the residential elevator market until around 2010.
This decision reflected a revision of what?
---
Answer: the ASME A17.1

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Seal script, which had evolved slowly in the state of Qin during the Eastern Zhou dynasty, became standardized and adopted as the formal script for all of China in the Qin dynasty (leading to a popular misconception that it was invented at that time), and was still widely used for decorative engraving and seals (name chops, or signets) in the Han dynasty period. However, despite the Qin script standardization, more than one script remained in use at the time. For example, a little-known, rectilinear and roughly executed kind of common (vulgar) writing had for centuries coexisted with the more formal seal script in the Qin state, and the popularity of this vulgar writing grew as the use of writing itself became more widespread. By the Warring States period, an immature form of clerical script called "early clerical" or "proto-clerical" had already developed in the state of Qin based upon this vulgar writing, and with influence from seal script as well. The coexistence of the three scripts small seal, vulgar and proto-clerical, with the latter evolving gradually in the Qin to early Han dynasties into clerical script runs counter to the traditional belief that the Qin dynasty had one script only, and that clerical script was suddenly invented in the early Han dynasty from the small seal script.
What was invented in the early Han dynasty from the small seal script?
A: clerical script

Context and question: After the Communist Party of China took power in 1949, the flag of China became a red flag with a large star symbolizing the Communist Party, and smaller stars symbolizing workers, peasants, the urban middle class and rural middle class. The flag of the Communist Party of China became a red banner with a hammer and sickle, similar to that on the Soviet flag. In the 1950s and 1960s, other Communist regimes such as Vietnam and Laos also adopted red flags. Some Communist countries, such as Cuba, chose to keep their old flags; and other countries used red flags which had nothing to do with Communism or socialism; the red flag of Nepal, for instance, represents the national flower.
What happened in 1950?
Answer: unanswerable

Question: Yale's residential college system was established in 1933 by Edward S. Harkness, who admired the social intimacy of Oxford and Cambridge and donated significant funds to found similar colleges at Yale and Harvard. Though Yale's colleges resemble their English precursors organizationally and architecturally, they are dependent entities of Yale College and have limited autonomy. The colleges are led by a master and an academic dean, who reside in the college, and university faculty and affiliates comprise each college's fellowship. Colleges offer their own seminars, social events, and speaking engagements known as "Master's Teas," but do not contain programs of study or academic departments. Instead, all undergraduate courses are taught by the Faculty of Arts and Sciences and are open to members of any college.
Is there an answer to this question: Who established Yale's residential college system?

Answer: Edward S. Harkness

Problem: Portugal:

But Sebastiao de Melo's greatest reforms were economic and financial, with the creation of several companies and guilds to regulate every commercial activity. He demarcated the region for production of Port to ensure the wine's quality, and this was the first attempt to control wine quality and production in Europe. He ruled with a strong hand by imposing strict law upon all classes of Portuguese society from the high nobility to the poorest working class, along with a widespread review of the country's tax system. These reforms gained him enemies in the upper classes, especially among the high nobility, who despised him as a social upstart.

What were de Melo's greatest reforms?
---
A:
economic and financial
