Based on the information from both charts, which other country does Russia compare most closely to?

| Metric | Russia | Brazil | Nigeria |
|--------------------|-----------|----------|---------|
| Population growth rate | -0.02% | 0.83% | 2.54% |
| Fertility rate | 1.61 | 1.81 | 5.31 |
| Life expectancy | 70 years | 73 years | 52 years |

Life expectancy (other chart):
- 84 years
- 54 years
- 77 years

Note: Compare the metrics of Russia with the other provided life expectancy data to determine the closest match.



Answer :

To determine which other country from Chart 1 compares most closely to Russia in terms of life expectancy, follow these steps:

1. List the life expectancy values for the countries in Chart 1:
[tex]\[ \text{Country 1:} \ 84 \, \text{years} \][/tex]
[tex]\[ \text{Country 2:} \ 54 \, \text{years} \][/tex]
[tex]\[ \text{Country 3:} \ 77 \, \text{years} \][/tex]

2. Note the life expectancy of Russia from Chart 2:
[tex]\[ \text{Russia:} \ 70 \, \text{years} \][/tex]

3. Calculate the absolute differences in life expectancy between Russia and each country in Chart 1:

- Difference between Russia and Country 1:
[tex]\[ |70 - 84| = 14 \, \text{years} \][/tex]

- Difference between Russia and Country 2:
[tex]\[ |70 - 54| = 16 \, \text{years} \][/tex]

- Difference between Russia and Country 3:
[tex]\[ |70 - 77| = 7 \, \text{years} \][/tex]

4. Identify the minimum difference:
- Differences are 14 years, 16 years, and 7 years.

Thus, the smallest difference is 7 years.

5. Find the corresponding country in Chart 1 with the smallest difference:
- Country 3 has a life expectancy of 77 years, which is 7 years different from Russia's 70 years.

Therefore, based on the life expectancy, Russia most closely compares to Country 3 from Chart 1.
