1)Find out how supermarkets are organised to attract as many customers as possible and to encourage them to buy more.

Supermarkets are designed to be a shopper's paradise. Everything, from the lighting to the music to the layout of the store, is carefully planned to entice customers and encourage them to buy more. For example, the placement of certain products is not left to chance. Items that people typically need, like milk and bread, are usually located at the back of the store, forcing customers to walk past other items in order to get there. Similarly, the end-caps of aisles are often used to showcase new or popular products, which can attract customers and prompt them to make impulse purchases.

In addition to strategic product placement, supermarkets also use sensory cues to stimulate shoppers' senses and create a pleasant shopping experience. Soft lighting, pleasant scents, and soothing music can help shoppers feel relaxed and comfortable, which can encourage them to linger in the store and spend more money.

Overall, supermarkets are organized in a way that maximizes sales and profits. While this can sometimes feel overwhelming to shoppers, it's important to remember that stores are simply trying to make a profit, and there are ways to shop smart and avoid overspending.

2)Do some research into jobs that don’t exist any more ( but were common, e.g. one or two hundreds years ago). Find out why there is no need for them.

One job that no longer exists is the town crier. Before the invention of mass communication technologies like newspapers and radio, town criers were responsible for delivering news and announcements to the public. They would walk through the streets ringing a bell or banging a drum to gather people's attention, and then recite the news in a loud, clear voice.

Another job that has become obsolete is the lamplighter. Before the widespread use of electric lights, gas lamps were used to illuminate streets and walkways. Lamplighters were responsible for lighting and extinguishing these lamps each day. However, with the advent of electric lighting, the job became unnecessary.

Similarly, the job of the ice cutter has disappeared due to advances in refrigeration technology. Before refrigerators were invented, ice was harvested from frozen lakes and rivers and transported to cities to be sold. Ice cutters were responsible for cutting the ice into blocks and storing it in ice houses, where it could be kept cool throughout the summer months.

Overall, advances in technology and changes in societal needs have rendered many jobs obsolete over time. While this can be difficult for workers in affected industries, it's also a reminder of the importance of adaptability and innovation in the face of change.
