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.
How much chicken soup does the Rehydration Project recommend adding?
A: unanswerable

To this day, most hunter-gatherers have a symbolically structured sexual division of labour. However, it is true that in a small minority of cases, women hunt the same kind of quarry as men, sometimes doing so alongside men. The best-known example are the Aeta people of the Philippines. According to one study, "About 85% of Philippine Aeta women hunt, and they hunt the same quarry as men. Aeta women hunt in groups and with dogs, and have a 31% success rate as opposed to 17% for men. Their rates are even better when they combine forces with men: mixed hunting groups have a full 41% success rate among the Aeta." Among the Ju'/hoansi people of Namibia, women help men track down quarry. Women in the Australian Martu also primarily hunt small animals like lizards to feed their children and maintain relations with other women.
What is the success rate for male Aeta hunters?
A: 17%

The second-largest is the Technische Universität Ilmenau with 7,000 students, founded in 1894, which offers many technical disciplines such as engineering and mathematics. The University of Erfurt, founded in 1392, has 5,000 students today and an emphasis on humanities and teacher training.
