(A) After the Colonial period's 50 percent mortality rate, life expectancy improved for children, but  （？核对：the colonial period’s 形式不正确！因为不是有生命的东西）

(B) Even though children's life expectancy, which improved over the Colonial period's 50 percent mortality rate,  （even though 后面直接加名词不正确！）

(C) Although life expectancy for children improved after the Colonial period, during which the mortality rate was 50 percent,

(D) While there was an improvement in life expectancy for children after the 50 percent mortality rate of the Colonial period, still有improve动词形式，就不用名词形式improvement.

(E) Despite children's life expectancy improvement from the Colonial period's 50 percent mortality rate,despite后面应该加一个句子，而不是一个单纯的名词短语。

E.DESPITE+名词，不过although+句子往往优于他。
