The key answer of exercise 1

In April 2000 journalists at Esquire decided that life at the magazine was getting a bit boring. So they published an article about FreeWheelz, an Internet company that gave customers free cars which were covered in advertising. The article claimed that FreeWheelz 'will transform the auto industry more than Henry Ford did.' The company hadn't yet become famous but it would 'on 1 April, when FreeWheelz launches on the web for real.' Readers who saw the website, which had been created by the author of the article, were impressed. Within days, the site had received over a thousand hits and messages from other entrepreneurs who claimed they had been planning similar businesses. The website contained a questionnaire for potential clients which included a number of bizarre questions such as 'Does hair loss concern you?' In the following edition, the magazine owned up, explaining that the article had been an April Fools' hoax. The magazine was preparing to forget all about it when suddenly an offer for the domain name FreeWheel came in. The author of the article sold the name for $25,000, splitting the profits with the owners of the magazine. The conclusion? Never trust a strange story which contains the date 1 April.
