Problem: 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 can be used to prevent dehydration?
The answer is the following: Oral rehydration solution (ORS)

Problem: As a result of the change in its status and the arrival of the Portuguese royal family, Brazilian administrative, civic, economical, military, educational, and scientific apparatus were expanded and highly modernized. Portuguese and their allied British troops fought against the French Invasion of Portugal and by 1815 the situation in Europe had cooled down sufficiently that Joao VI would have been able to return safely to Lisbon. However, the King of Portugal remained in Brazil until the Liberal Revolution of 1820, which started in Porto, demanded his return to Lisbon in 1821.
Until when did the King of Portugal remain in Brazil?
The answer is the following: until the Liberal Revolution of 1820

Problem: On 1 May, The Sun claimed to have 'sponsored' a British missile. Under the headline "Stick This Up Your Junta: A Sun missile for Galtieri's gauchos", the newspaper published a photograph of a missile, (actually a Polaris missile stock shot from the Ministry of Defence) which had a large Sun logo printed on its side with the caption "Here It Comes, Senors..." underneath. The paper explained that it was 'sponsoring' the missile by contributing to the eventual victory party on HMS Invincible when the war ended. In copy written by Wendy Henry, the paper said that the missile would shortly be used against Argentinian forces. Despite this, it was not well received by the troops and copies of The Sun were soon burnt. Tony Snow, The Sun journalist on HMS Invincible who had 'signed' the missile, reported a few days later that it had hit an Argentinian target.
What did the wording on the side of The Sun missile state?
The answer is the following: "Here It Comes, Senors..."
