To determine which two countries lost the smallest percentage of their populations, let's examine the percentage loss figures for each country. The given data is:
- Russia: 1.1%
- France: 1.5%
- UK: 0.24%
- Italy: 1.6%
- Serbia: 5.7%
- US: 0.1%
We need to identify the two smallest percentages from these values. The smallest percentage is:
- US: 0.1%
Followed by:
- UK: 0.24%
Thus, the two countries that lost the smallest percentage of their populations are the US and the UK.
The correct answer is:
the US and the UK
