Reading the passage carefully and answer the given questions.

It is absolutely fascinating to think about the future, as technology is rapidly advancing and in 40 years’ time, who knows what we’ll be able to do with it. Scientists have recently predicted that by 2050 the population of the world will be over ten billion and technology will have advanced so greatly that we will have far more information about all known diseases (and possibly cures), we will all be living in eco houses and will no longer face sky high electricity bills and we may even be able to take a holiday to Mars.

Our daily lives will most definitely be littered with all kinds of new technologies that help us do the things we hate the most in 2017! House robots will be a likely feature in all homes and will help run the family home, take out the rubbish, prepare food and hoover the house from top to bottom. Our kitchen gadgets (such as your fridge, cooker, microwave and dishwasher) will also be ‘robotic’ and will email or text us, users, when a food item has gone out of date or has been used up. Similarly, the fridge has a built-in camera so that when you are at the supermarket, you can log in to your fridge and check what you need to stock up on.

It is predicted that by 2050, we will all have ‘weekly digital health checks’ in our homes, which run sensors over our bodies to check for signs of ill health and any abnormalities. Conditions can instantly be recognized by the ‘virtual doctor’ inside the health machine and treated immediately, and if you need a prescription – it will be ordered and sent out automatically. If the digital health check picks up on a person being overweight, they will send a signal to the domestic house computer to modify their diet and book in for gym sessions. Because of all this immediate treatment, people will live far longer and won’t be wiped out by disease or forms of cancer. Medical conditions that are considered rare today, will be far more known about and will be able to be cured quickly and efficiently.
