All errors in this SC are meaning errors; none is grammatical one.

Hi Experts,

Use of the present perfect "have led" is incorrect, as we're referring to the past - (1876-1904.) Eliminate B and C.

D) There were concerns about public health leading to the construction between 1876 and 1904 of three separate sewer systems serving
It sounds as though "leading to the construction..." is modifying "public health." So we're talking about the kind of public health that would lead to the construction of sewer systems? Clearly not the intended meaning. D is out.

E. There were concerns leading between 1876 and 1904 to the construction of three separate sewer systems for serving
 The concerns were leading between 1876 and 1904? What on earth does that mean? This is incoherent. Eliminate E.

We're left with A
