1:A - Butter is quite a neutral flavour. It can be a little more sweet or savoury depending on the milk that it’s made from, or if it is salted butter, then it’s savoury! , 2:C - The largest sandwich ever was made by a restaurant called Wild Woody’s Chill and Grill in Roseville, Michigan, US, in 2005. It weighed 2,467.5kg – about the same weight as 705 average-sized newborn babies! The filling was corned beef, cheese, lettuce and mustard, inside 1,618.4kg of bread. , 3:B - The average adult has about 10 pints, or 5.7 litres, of blood in their bodies, but this depends on how big you are! , 4:A - When you think about or smell or see food, saliva is produced in your mouth. Saliva contains enzymes that help break down food, so when your mouth makes the watery saliva, it is because your body is preparing for food. , 5:D - When you run or exercise, your muscles need more oxygen than they usually do, so your heart beats faster to pump oxygenated blood around your body more quickly.
