Questions are based on the following passage．

Without proper planning, tourism can cause problems．For example, too many tourists can crowd public places that are also enjoyed by the inhabitants of a country． If tourists create too much traffic, the inhabitants become annoyed and unhappy． They begin to dislike tourists and to treat them impolitely． They forget how much tourism can help the country's economy．

(79) It is important to think about the people of a destination country and how tourism affects them． Tourism should help a country keep the customs and beauty that attract tourists． Tourism should also advance the well-being of local inhabitants．

Too much tourism can be a problem． If tourism grows too quickly, people must leave other jobs to work in the tourism industry． This means that other parts of the country's economy can suffer．

On the other hand, if there is not enough tourism, people can lose jobs． Businesses can also lose money． It costs a great deal of money to build large hotels, airports, air terminals, first- class roads, and other support facilities needed by tourist attractions． (80) For example, a major international-class tourism hotel can cost as much as 50 thousand dollars per room to build． If this room is not used most of the time, the owners of the hotel will lose money．

Building a hotel is just a beginning． There must be many support facilities as well, including roads to get to the hotel, electricity, sewers to handle waste, and water． All of these support facilities cost money．If they are not used because there are not enough tourists, jobs and money are lost．

About Turkey

Some of the concerns surrounding Turkey"s application to join the European Union， to be voted on by the EU"s Council of Ministers on December 17th， are economic—— in particular， the country"s relative poverty. Its GDP per head is less than a third of the average for the 15 pre-2004 members of the EU. But it is not far offthat of one of the ten new members which joined on May 1st 2004 （Latvia）， and it is much the same as those of two countries， Bulgaria and Romania， which this week concluded accession talks with the EU that could make them full members on January 1 st 2007.

Furthermore， the country"s recent economic progress has been， according to Donald Johnston，the secretary-general of the OECD，"stunning". GDP in the second quarter of the year was 13.4% higher than a year earlier， a rate of growth that no EU country comes close to matching. Turkey"s inflation rate has just fallen into single figures for the first time since 1972， and this week the country reached agreement with the IMF on a new three-year， $10 billion economic programme that will， according to the IMF"s managing director， Rodrigo Rato，"help Turkey... reduce inflation toward European levels， and enhance the economy"s resilience".

Resilience has not historically been the country"s economic strong point. As recently as 2001， GDP fell by over 7%. It fell by more than 5% in 1994， and by just under 5% in 1999. Indeed， throughout the 1990s growth oscillated like an electrocardiogram recording a violent heart attack. This irregularity has been one of the main reasons （along with red tape and corruption） why the country has failed dismally to attract much-needed foreign direct investment. Its stock of such investment （as a percentage of GDP） is lower now than it was in the 1980s， and annual inflows have scarcely ever reached $1 billion （whereas Ireland attracted over $25 billion in 2003， as did Brazil in every year from 1998 to 2000）.

One deterrent to foreign investors is due to disappear on January 1st 2005. On that day， Turkey will take away the right of virtually every one of its citizens to call themselves a millionaire. Six noughts will be removed from the face value of the lira; one unit of the local currency will henceforth be worth what lm are now， i. e.， about E0.53 （$0.70）. Goods will have to be priced in both the new and old lira for the whole of the year， but foreign bankers and investors can begin to look forward to a time in Turkey when they will no longer have to juggle mentally with indeterminate strings of zeros.
