Problem: Bird:

Domesticated birds raised for meat and eggs, called poultry, are the largest source of animal protein eaten by humans; in 2003, 76 million tons of poultry and 61 million tons of eggs were produced worldwide. Chickens account for much of human poultry consumption, though domesticated turkeys, ducks, and geese are also relatively common. Many species of birds are also hunted for meat. Bird hunting is primarily a recreational activity except in extremely undeveloped areas. The most important birds hunted in North and South America are waterfowl; other widely hunted birds include pheasants, wild turkeys, quail, doves, partridge, grouse, snipe, and woodcock. Muttonbirding is also popular in Australia and New Zealand. Though some hunting, such as that of muttonbirds, may be sustainable, hunting has led to the extinction or endangerment of dozens of species.

Problem: Diarrhea:

Oral rehydration solution (ORS) (a slightly sweetened and salty water) can be used to prevent dehydration. Standard home solutions such as salted rice water, salted yogurt drinks, vegetable and chicken soups with salt can be given. Home solutions such as water in which cereal has been cooked, unsalted soup, green coconut water, weak tea (unsweetened), and unsweetened fresh fruit juices can have from half a teaspoon to full teaspoon of salt (from one-and-a-half to three grams) added per liter. Clean plain water can also be one of several fluids given. There are commercial solutions such as Pedialyte, and relief agencies such as UNICEF widely distribute packets of salts and sugar. A WHO publication for physicians recommends a homemade ORS consisting of one liter water with one teaspoon salt (3 grams) and two tablespoons sugar (18 grams) added (approximately the "taste of tears"). Rehydration Project recommends adding the same amount of sugar but only one-half a teaspoon of salt, stating that this more dilute approach is less risky with very little loss of effectiveness. Both agree that drinks with too much sugar or salt can make dehydration worse.

What is the WHO's recipe for ORS?

A: one liter water with one teaspoon salt (3 grams) and two tablespoons sugar (18 grams) added

Problem: Valencia:

Valencia is a bilingual city: Valencian and Spanish are the two official languages. Spanish is official in all of Spain, whereas Valencian is official in the Valencian Country, as well as in Catalonia and the Balearic Islands, where it receives the name of Catalan. Despite the differentiated denomination, the distinct dialectal traits and political tension between Catalonia and the Valencian Country, Catalan and Valencian are mutually intelligible and are considered two varieties of the same language.
Valencian has been historically repressed in favour of Spanish. The effects have been more noticeable in the city proper, whereas the language has remained active in the rural and metropolitan areas. After the Castille-Aragon unification, a Spanish-speaking elite established itself in the city. In more recent history, the establishment of Franco's military and administrative apparatus in Valencia further excluded Valencian from public life. Valencian recovered its official status, prestige and use in education after the transition to democracy in 1978. However, due to industrialisation in recent decades, Valencia has attracted immigration from other regions in Spain, and hence there is also a demographic factor for its declining social use. Due to a combination of these reasons, Valencia has become the bastion of anti-Catalan blaverism, which celebrates Valencian as merely folkloric, but rejects the existing standard which was adapted from Catalan orthography.
Spanish is currently the predominant language in the city proper but, thanks to the education system, most Valencians have basic knowledge of both Spanish and Valencian, and either can be used in the city. Valencia is therefore the second biggest Catalan-speaking city after Barcelona. Institutional buildings and streets are named in Valencian. The city is also home to many pro-Valencian political and civil organisations. Furthermore, education entirely in Valencian is offered in more than 70 state-owned schools in the city, as well as by the University of Valencia across all disciplines.

When did Valencian regain its offical status?

A: 1978

Problem: Data compression:

In lossy audio compression, methods of psychoacoustics are used to remove non-audible (or less audible) components of the audio signal. Compression of human speech is often performed with even more specialized techniques; speech coding, or voice coding, is sometimes distinguished as a separate discipline from audio compression. Different audio and speech compression standards are listed under audio coding formats. Voice compression is used in internet telephony, for example, audio compression is used for CD ripping and is decoded by the audio players.

What is used for CD ripping?
