Problem: Chinese characters:

Just as Roman letters have a characteristic shape (lower-case letters mostly occupying the x-height, with ascenders or descenders on some letters), Chinese characters occupy a more or less square area in which the components of every character are written to fit in order to maintain a uniform size and shape, especially with small printed characters in Ming and sans-serif styles. Because of this, beginners often practise writing on squared graph paper, and the Chinese sometimes use the term "Square-Block Characters" (方块字 / 方塊字, fāngkuàizì), sometimes translated as tetragraph, in reference to Chinese characters.

What can sometimes be translated as tetragraph?

A: Square-Block Characters


Problem: Swiss are fans of football and the national team is nicknamed the 'Nati'. The headquarters of the sport's governing body, the International Federation of Association Football (FIFA), is located in Zürich. Switzerland hosted the 1954 FIFA World Cup, and was the joint host, with Austria, of the Euro 2008 tournament. The Swiss Super League is the nation's professional club league. For the Brasil 2014 World Cup finals tournament, the country's German-speaking cantons will be closely monitored by local police forces to prevent celebrations beyond one hour after matches end. Europe's highest football pitch, at 2,000 metres (6,600 ft) above sea level, is located in Switzerland and is named the Ottmar Hitzfeld Stadium.

The nonprofit landscape is highly varied, although many people have come to associate NPOs with charitable organizations. Although charities do comprise an often high profile or visible aspect of the sector, there are many other types of nonprofits. Overall, they tend to be either member-serving or community-serving. Member-serving organizations include mutual societies, cooperatives, trade unions, credit unions, industry associations, sports clubs, retired serviceman's clubs and peak bodies – organizations that benefit a particular group of people i.e. the members of the organization. Typically, community-serving organizations are focused on providing services to the community in general, either globally or locally: organizations delivering human services programs or projects, aid and development programs, medical research, education and health services, and so on. It could be argued many nonprofits sit across both camps, at least in terms of the impact they make. For example, the grassroots support group that provides a lifeline to those with a particular condition or disease could be deemed to be serving both its members (by directly supporting them) and the broader community (through the provision of a helping service for fellow citizens).
Who does an NPO usually serve?
A: member-serving or community-serving

In 1980 half of all the industrial jobs in Mexico were located in Mexico City. Under relentless growth, the Mexico City government could barely keep up with services. Villagers from the countryside who continued to pour into the city to escape poverty only compounded the city's problems. With no housing available, they took over lands surrounding the city, creating huge shantytowns that extended for many miles. This caused serious air pollution in Mexico City and water pollution problems, as well as subsidence due to overextraction of groundwater. Air and water pollution has been contained and improved in several areas due to government programs, the renovation of vehicles and the modernization of public transportation.
How many of the industrial jobs in the county were based in Mexico City in the late 20th century?
A:
half
