<span>Isadora Duncan, the dancer who created her own style and flavour in dancing and also invented a new dance form with her creative ideas, mixing traditional ballet with natural movement. She named her dance institute "Isadorables". After her death the institute is run by her faithful followers who stood by her in all times of despair. She hated the romantic ballet during the time, when she had found a new dance form and there were no takers for her dance, she traveled around Europe to perform her dance along with her adopted daughters, and finally decided to settle in Soviet Union as a first migrant but unfortunately she met her fate while travelling in a car on a cold evening strangled to death by her scarf, that stuck in the wheel of the very own car she was travelling.</span>
Let us take any other country say India for example to understand this scenario.Say $1= Rs 60 ,then if India imports stuffs from USA,India will pay less,Rs 60 for $1. Say later on its $1=Rs 70,India will have to pay more money for the same import as Rs 60 is not enough now to be equal to dollar,India will have to pay Rs 10 more,so India will reduce imports from USA and will try to import from some country where the same product is cheaper,say China where China gives huge subsidy up to 50% on each product being exported.
