Exercise 9. Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the questions.

Super Size Me is a 2004 film by Morgan Spurlock, in which he documents his experiment to eat only McDonald's fast food three times a day, every day, for thirty days.

Spurlock made himself a short list of rules for the experiment, including an obligation to eat all of the three meals he ordered. He also had to ‘Super Size’, which means accepting a giant portion every time the option was offered to him. He ended up vomiting after the first Super Size meal he finished, after taking nearly twenty minutes to consume it.

After five days Spurlock put on almost 5kg, and he soon found himself feeling depressed, with no energy. The only thing that got rid of his headaches and made him feel better was another McDonald's meal, so his doctors told him he was addicted. More seriously, around day twenty, he started experiencing heart palpitations and one of the doctors detected liver problems. However, in spite of his doctor's advice, Spurlock continued to the end of the month and achieved a total weight gain of 11kg. His body mass index also increased from a healthy 23.2 to an overweight 27.

It took Spurlock fifteen months to recover from his experiment and return to his original weight, but the film also had a wider impact. Just after its showing in 2004, McDonald's phased out the Super Size option and healthier options like salads appeared on the menu. Unfortunately, McDonald's denied the connection between the film and the changes, but it is interesting to note how closely they coincided with the release of the film.

Exercise 10. Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the questions.

In 2002, several obese teenagers in the USA sued McDonald's, claiming that the company was responsible for making them fat. They argued that McDonald's deliberately misled them into thinking that their cheeseburgers and other products were healthy and nutritious food. They claimed that the company had not warned them about the health problems that can result from eating too much salty, high-fat food and drinking too many sugary drinks: diabetes, high blood pressure and obesity. The mother of one of the children, who at the age of 15 weighed more than 180 kilograms, said in her statement: ‘I always believed McDonald's was healthy for my son.'

McDonald's rejected the claim that they were responsible for these teenagers’ health problems. ‘People don't go to sleep thin and wake up obese,' said McDonald's lawyer, Brad Lerman. 'The understanding of what hamburgers and French fries do has been with us for a long, long time,’ he added. The judge agreed, and dismissed the case, saying: 'it is not the place of the law to protect people against their own excesses.' In other words, if people choose to eat a lot of unhealthy food, they can't blame the company that sold it to them.

Other similar lawsuits against fast food companies in the USA have also failed. In 2005, the US House of Representatives passed a bill which became known as the 'Cheeseburger Bill'. It made it much harder for obese people to take legal action against the food industry. However, the bill has not ended the arguments about responsibility. There is some scientific evidence to suggest that fast food is addictive, and harmful too. So is selling fast food the same, in a way, as drug-dealing?
