Real GDP is calculated by adjusting nominal GDP for the GDP deflator: Real GDP = Nominal GDP ÷ (GDP Deflator/100).

1) Relevant knowledge points and concepts
- Nominal GDP measures output in current dollars; the GDP deflator is a price index (base 100).
- Dividing nominal GDP by (deflator/100) removes price level changes and yields real GDP in base-year dollars.
- Compare real GDP values across years to find the largest.

2) Step-by-step calculations (showing intermediate steps)
- 1980: Nominal = $14,000; Deflator = 70
  Real GDP = 14,000 ÷ (70/100) = 14,000 ÷ 0.70 = 20,000
- 1990: Nominal = $18,000; Deflator = 100
  Real GDP = 18,000 ÷ (100/100) = 18,000 ÷ 1.00 = 18,000
- 2000: Nominal = $22,000; Deflator = 220
  Real GDP = 22,000 ÷ (220/100) = 22,000 ÷ 2.20 = 10,000
- 2010: Nominal = $50,000; Deflator = 200
  Real GDP = 50,000 ÷ (200/100) = 50,000 ÷ 2.00 = 25,000
- 2015: Nominal = $60,000; Deflator = 300
  Real GDP = 60,000 ÷ (300/100) = 60,000 ÷ 3.00 = 20,000

3) Why the correct answer is correct
- The computed real GDP values are: 1980 = 20,000; 1990 = 18,000; 2000 = 10,000; 2010 = 25,000; 2015 = 20,000.
- The largest real GDP is 25,000 in 2010, so 2010 is the year with the highest real output after removing price effects.

4) Why the other options are incorrect
- 2000 (real GDP 10,000) is much lower due to a high deflator (220).
- 2015 and 1980 both yield real GDP = 20,000, which is less than 25,000.
- 1990 yields 18,000, also less than 25,000.

Conclusion: The year with the largest real GDP is 2010, which matches the provided correct answer.
