In the wake of the war, the Congress submitted, and the States ratified, the Thirteenth. Amendment (making slavery illegal), the Fourteenth Amendment. (defining and granting broad rights of national citizenship), and the. Fifteenth Amendment (forbidding racial discrimination in elec-. tions).

A key element in calculating the HDI is life expectancy at birth. The life expectancy factor helps to determine how long the average citizen lives, how healthy she can remain during her life and how much she can contribute in her working life.
So three plus one is equal to four and we get an HDI equal to four, right? Up here we had one ring and we had an HDI equal to one. Up here we had one double bond and an HDI equal to one. We could also calculate the HDI using a formula. So we could write that the hydrogen deficiency index is equal to one-half times what's in the parenthesis.
