Задача по теме: "Понимание прослушанного текста"

Решение:

It turned out that the common denominator between cultures, regardless of age, gender or context is: keys, money and, if you own one, a mobile phone. Why those three objects? Without wanting to sound hyperbolic, essentially it boils down to survival. Keys provide access to warmth and shelter, money is a very versatile tool that can buy food, transport and so on. A mobile phone is actually a great tool for recovering from emergency situations, especially if the first two fail. We’ve also started to see the mobile phone being used as the primary form of projecting your identity. For instance, if you live in a community with no street signs, because your street is off the map or not officially recognised, you find people are writing their phone numbers above their door.
