This question is based on Construction.
The intended meaning of this sentence is that because there were concerns about public health, three separate sewer systems were constructed between the years 1876 and 1904. These sewer systems were meant to serve metropolitan Boston.
Option B contains
a tense error. It has the present perfect tense “have led” but the sentence is about something that happened in the past - between 1876 and 1904. The correct tense would be the simple past tense. So, [color=#ff0000]Option B can be eliminated.
Option C contains
the same tense error as Option B. It also contains
an idiomatic error – for serving. The correct usage is – to serve. So,
Option C can also be eliminated.
In Option D,
the use of the participles “leading” and “serving” leads to an inconsistency in the time frame that is conveyed. The sentence makes a statement about the past and there is no sense of continuity required. So,
Option D can be eliminated.
Option E is distorted. It conveys the meaning that there were concerns connecting the two years mentioned. The placement of the phrase ‘leading between’ immediately before the two years is indicative of that meaning.
There is also an idiomatic error – for serving. The correct idiom is “to serve”. So,
Option E can be eliminated.
Option A has the most appropriate order of words and the correct idiomatic usage. Therefore, A is the best option.Jayanthi Kumar.
