Question 15

City has taken bike lanes to a whole new level, installing

Since 2006, the city has taken bike lanes to a whole new level, installing more than 250 miles around the city's five boroughs. This revision effectively connects the two ideas into a cohesive thought while maintaining clarity.

A) city has taken bike lanes to a whole new level, they installed

This option incorrectly uses a comma to separate two independent clauses, resulting in a comma splice. Furthermore, it fails to create a smooth connection between the two thoughts, making it less effective than the correct answer.

B) city, which has taken bike lanes to a whole new level, installing

While this option introduces a relative clause, it awkwardly shifts the focus and creates an incomplete thought. The phrase "installing" lacks a clear subject, making the sentence grammatically incorrect and confusing.

C) city has taken bike lanes to a whole new level and installing

This option mixes verb forms; "has taken" is in the present perfect tense, while "installing" presents an ongoing action without proper grammatical structure. This inconsistency in tense fails to provide a coherent connection between the two actions.

D) city has taken bike lanes to a whole new level, installing

This option correctly combines the two ideas into a single, fluid sentence. It maintains the present perfect tense and uses the participial phrase "installing" to indicate the subsequent action taken by the city, resulting in a grammatically correct and clear statement.

Conclusion

The correct answer, option D, effectively connects the city's action of enhancing bike lanes with the specific outcome of installing new mileage. The other options either contain grammatical errors or fail to present a coherent and fluid thought, demonstrating why they are less suitable for revision.
