Concerns about public health led to the construction between 1876 and 1904 of three separate sewer systems to serve metropolitan Boston.
A. Concerns about public health led to the construction between 1876 and 1904 of three separate sewer systems to serve
B. Concerns about public health have led to the construction of three separate sewer systems between 1876 and 1904 to serve
C. Concerns about public health have led between 1876 and 1904 to the construction of three separate sewer systems for serving
D. There were concerns about public health leading to the construction between 1876 and 1904 of three separate sewer systems serving
E. There were concerns leading between 1876 and 1904 to the construction of three separate sewer systems for serving
------------------------------------------------------------
I did get this question right, but I want to understand the difference between "for serving" and "to serve" in the choices. My question is related to "for + verbing" form used in choices C and E.
I do see a tense error in C and a meaning error in E. But are both the "to" form and the "for" acceptable in this sentence? "to" form indicates intention, whereas "for" form indicates goal. Both fit readily in the sentence.
