Read the passage below and then choose the right answer (A, B, C, D or E) to the questions from 13 to 18: Lower prices will put mobile phones, and their attendant economic benefits, into the hands of millions more people. Mobile phones let fishermen and farmers check prices in different markets before selling produce, make it easier for people to find work, allow quick and easy transfer of funds and boost economic development. Prepaid calling plans mean subscribers do not need to have a bank account, micro credit loans provide people with the means to buy handsets which they can then rent out by the call, and entire villages can share a phone. Mobile has created more entrepreneurs in Africa in the past five years than anything else, But as the cost of handsets falls another barrier to adoption will become more apparent: the high taxes and tariffs imposed by governments in many developing countries, which regard mobile telecoms as a valuable source of revenue. Such taxes, which account for a large proportion of the cost of mobile telephone in some countries, stifle the very economic development that governments are trying to promote.
