Affiliate Marketing Secrets

I have to write a handout for English class ( I’m from Austria, bdw) and the teacher has no time to correct it in advance. I don’t want to give a handout full of mistakes to my class mates, so could you please tell me the mistakes in the four texts below? thanks a lot!
Chips with Everything
Chips, crisps, potato watches – they are almost everywhere, eaten with almost every meal: potatoes. But have you ever asked where they came from? It all started in Peru, where they grew potatoes over 2,000 years ago, but they were smaller than today and tasted bitter. Spanish explorers discovered them in the 1550s and brought them to Spain. However, people did not really like them and they were mainly given to slaves and prisoners as they were quite cheap. They slowly made their way through Europe, but people kept thinking they were poisonous. But then supposedly King Louis of France, who loved potatoes, planted them in the royal gardens to make them seem valuable. His plan worked: the plants were stolen and became a popular part of French diet.
The chips were probably invented by the Belgians. In England they were first mentioned by the famous author Charles Dickens. In America they are called French fries because American soldiers tasted them first in France during World War I – nowadays the Americans eat over 20 million tonnes of chips a year.
The crisps were invented by a Native-American chef, whose customer kept demanding his fried potatoes sliced more and more thinly. The dish was an immediate success.
The Fortune Cookie
Fortune cookies are small sweet biscuits that are served at the end of a meal in a Chinese restaurant. Written on a piece of paper inside them is your fortune, for instance ‘You will write a book one day’. The Chinese people have always given each other sweet Moon Cakes on special occasions. When the Mongols occupied China, the Chinese used them as a way to send secret messages to each other. When many Chinese people went to America during the gold rush they kept putting messages of hope inside biscuits on celebrations. And as they settled in California and opened restaurants, they continued this tradition.
A Short History of the Pizza
The very origin of today’s pizza is in Greece where people first put various ingredients onto a flat round dough –cake and baked it over an open fire. This dish was called ‘pita’ which is also where the name ‘pizza’ comes from. The Etruscans brought it to Italy. It spread in Europe, but it was still a dish for poor people. When the tomatoes came to Europe people started putting them onto their pitas. Slowly the newly born pizza became a local specialty in Neapel. But then King Umberto and his wife Queen Margherita visited Neapel and wanted to try the new dish although it still stuck with the reputation of being a poor people’s meal. A chef put tomatoes, mozzarella and basil onto it – in order to reassemble the Italian flag – and named his creation ‘Margherita’. Apparently the queen was so enthusiastic about the result the pizza became acceptable for the nobility as well.
Coca Cola
Coca Cola was invented by an American pharmacist in order to cure diseases like impotence, headache and morphine addiction. He sold it to the business-man Candler who founded the Coca Cola Company and started an aggressive marketing plan making it one of the most popular drinks of America. Today, more than 1 billion drinks of Coca Cola are consumed per day.
