Difficulty: HardShifts in Construction

Determine the form of the verb 'expand' that correctly completes the sentence without introducing an inconsistent shift in grammatical construction.

Answer:To revitalize the downtown area, the city council proposed a series of urban renewal projects. The committee recommended both renovating the historic facade of the theater and 【expanding】 the interior seating capacity. By implementing these modernizations, the city hopes to attract larger touring productions and boost local tourism.

Answer

expanding
The correct answer is the gerund form 'expanding'. The sentence uses the correlative conjunction 'both... and' to connect two actions. The first action is introduced by the gerund 'renovating' ('renovating the historic facade'). To maintain grammatical parallelism and avoid an unnecessary shift in construction, the second action must also use a gerund ('expanding the interior seating capacity').

Step-by-Step Solution

1
Identify the parallel structure established by the correlative conjunction 'both... and...'.
The first item in the parallel structure is the gerund phrase starting with the word 'renovating'.
Correlative conjunctions require the coordinated elements to share the same grammatical form to avoid a shift in construction.
2
Determine the required grammatical form for the second item in the coordinated structure.
The second item must also begin with a gerund (the '-ing' verb form acting as a noun).
Matching the gerund form 'renovating' with another gerund ensures grammatical consistency and parallelism.
3
Conjugate the verb 'expand' into its gerund form.
The gerund form of 'expand' is 'expanding'.
This form completes the coordinated phrase parallelly as 'both renovating... and expanding...'
