Economic development is necessary if we want     1     (improve) society but finding and keeping the right balance between progress and the protection of cultural sites can be a big challenge, which can sometimes lead to great solutions. Perhaps the     2     (good) example is shown by UNESCO,     3     runs a programme that prevents world cultural heritage sites around the world from     4     (disappear).

In the 1950s, the Egyptian government     5     (want) to build a new dam across the Nile, but the proposal led to protests because water from the dam would likely damage some temples and destroy cultural relics. Finally, the government turned     6     the United Nations for help.

A committee     7     (establish) to limit damage to the Egyptian buildings and prevent the     8     (lose) of cultural relics. The group asked for contributions from different departments and raised funds within the international community. Fifty countries donated nearly $80 million to the project.

When the project ended in 1980, it was considered     9     great success. As is shown, if a problem seems too difficult for a single nation, the     10     (globe) community can sometimes provide a solution.
