Question: Context: Something in chocolate could be used to stop coughs and lead to more effective medicines, say UK researchers. Their study found that theobromine , found in cocoa, was nearly a third more effective in stopping coughs than codeine, which was considered the best cough medicine at present. The Imperial College London researchers who published their results online said the discovery could lead to more effective cough treatment. "While coughing is not necessarily harmful it can have a major effect on the quality of life, and this discovery could be a huge step forward in treating this problem," said Professor Peter Barnes. Ten healthy volunteers were given theobromine, codeine or placebo, a pill that contains no medicine, during the experiment. Neither the volunteers nor the researchers knew who received which pill. The researchers then measured levels of capsaicin, which is used in research to cause coughing and as a sign of how well the medicines are stopping coughs. The team found that, when the volunteers were given theobromine, the capsaicin needed to produce a cough was around a third higher than in the placebo group. When they were given codeine they needed only slightly higher levers of capsaicin to cause a cough compared with the placebo. The researchers said that theobromine worked by keeping down a nerve activity , which cause coughing. They also found that unlike some standard cough treatments, theobromine caused no side effects such as sleepiness. 
 Question: What was used in the experiment to cause coughing?

Answer: capsaicin.


Question: Context: A solution is a mixture of two or more substances in which dissolved particles are distributed evenly throughout the solution. The substance that dissolves in a solution is called the solute, and the substance that does the dissolving is called the solvent. The concentration of a solution is the amount of solute in a given amount of solution. A solution with a lot of dissolved solute has a high concentration and is called a concentrated solution. A solution with little dissolved solute has a low concentration and is called a dilute solution. The concentration of a solution represents the percentage of the solution that is the solute. You can calculate the concentration of a solution using this formula: Concentration = Mass (or volume) of Solute Mass (or volume) of Solution 100% For example, if a 100-gram solution of salt water contains 3 grams of salt, then its concentration is: Concentration = 3g 100g 100% = 3% Q: A 1000 mL container of brand A juice drink contains 250 mL of juice and 750 mL of water. A 600 mL container of brand B juice drink contains 200 mL of juice and 400 mL of water. Which brand of juice drink is more concentrated, brand A or brand B? 250 mL 1000 mL 100% = 25% 200 mL 600 mL 100% = 33% A: Concentration(A) = Concentration(B) = You can conclude that brand B is more concentrated. 
 Question: a solution with a small amount of solute for a given amount of solution is called

Answer: dilute.


Question: Context: Angyali udvozlet, aka "The Annunciation", is a surreal account of the history of humanity as portrayed entirely by children between the ages of 8 and 12. The film begins with the biblical story as Adam (Peter Bocsor) and Eve (Julia Mero), are deceived by Lucifer (Eszter Gyalog) -- three very photogenic leads -- into tasting the "Forbidden Fruit". They are thus chased out of the Garden of Eden by the Angel of Death and, in a vision, sent on an existential journey through western European history.Always followed closely and influenced by the deceptively sweet, but contemptuous Lucifer, we follow Adam through The Plague, wars, Byzantium's wretched cripples, the French Revolution, the squalor of Dickensian London, and a final return to the scene of the crucifixion. Of course the picture makes a case for its premise -- that of the consequences of Original Sin -- yet does so in a very unique way. In the closing scene, Lucifer says, "Why did I strive to achieve greatness in man, who is...in knowlege a pygmy, in blindness a giant?" This reflects the somewhat nihilistic view of a nation still under the boot of Soviet communism.This rare movie may be one of the best (and only child-starred) art films ever. 
 Question: Where are Adam and Eve cast out of?

Answer:
garden of eden
