To find how much the debt increased in the 50-year period, we need to subtract the debt in 1971 from the debt in 2021.

Debt increase = Debt in 2021 - Debt in 1971
Debt increase = $2.9617×1013 - $3.98×1011

Calculating the subtraction:

Debt increase = $29.617×1012 - $3.98×1011
Debt increase = $29.219×1012

Therefore, the debt increased by $2.9219×1013 in the 50-year period.

The correct answer is: $2.9219×1013
