To determine the answers to the following questions, let's analyze the given data in the table:

1. Population growth rate
2. Fertility rate
3. Life expectancy

### Question 1: Which country is growing the fastest?

To find the fastest growing country, we need to compare the population growth rates:

- Russia: -0.02%
- Brazil: 0.83%
- Nigeria: 2.54%

The highest population growth rate among these is 2.54%, and it belongs to Nigeria. Therefore, Nigeria is growing the fastest.

### Answer: Nigeria

### Question 2: Which country is growing the slowest?

To find the slowest growing country, we again compare the population growth rates:

- Russia: -0.02%
- Brazil: 0.83%
- Nigeria: 2.54%

The lowest population growth rate is -0.02%, which belongs to Russia. Therefore, Russia is growing the slowest.

### Answer: Russia

### Question 3: Which factor most likely contributes to Brazil's population growth rate?

We need to consider the factors provided in the table (fertility rate and life expectancy) to determine what most likely contributes to Brazil's population growth rate.

For Brazil:
- Fertility rate: 1.81
- Life expectancy: 73 years

Comparing the fertilities and life expectancies can help us infer the influence on the population growth rate. High fertility rates generally have a more direct influence on population growth. Therefore, the most likely contributing factor to Brazil's population growth rate is its fertility rate.

### Answer: Fertility rate

### Question 4: Which factor most likely contributes to Nigeria's population growth rate?

Similarly, look at Nigeria's data:
- Fertility rate: 5.31
- Life expectancy: 52 years

Nigeria has a significantly higher fertility rate of 5.31, which considerably influences its high population growth rate. Hence, the most likely contributing factor to Nigeria's population growth rate is also its fertility rate.

### Answer: Fertility rate

With these detailed explanations, we can conclude:

1. The fastest growing country is Nigeria.
2. The slowest growing country is Russia.
3. The factor that most likely contributes to Brazil's population growth rate is the fertility rate.
4. The factor that most likely contributes to Nigeria's population growth rate is the fertility rate.
