Question

Difficulty: EasyParallel Structure

A student is writing an essay about modern agricultural technology. Which word completes the passage so that it conforms to the conventions of Standard English and maintains a parallel structure?

Answer:In response to the challenges of traditional agriculture, researchers are developing modern vertical farming systems. These innovative indoor facilities are designed to conserve freshwater resources, reduce carbon emissions, and 【maximize】 crop yields throughout the entire year. By stacking crops vertically and using controlled LED lighting, these systems optimize land use and minimize environmental impact.

Answer

maximize (or a similar base verb such as increase, boost, improve, optimize, or enhance)
The sentence lists three functions of vertical farming systems following the phrase 'are designed to'. The first function is 'conserve' (a base verb) and the second is 'reduce' (also a base verb). To maintain a parallel grammatical structure, the third function must also be a base verb. Words such as 'maximize', 'increase', 'boost', or 'improve' maintain this parallel base verb form.

Step-by-Step Solution

1
Identify the parallel elements in the sentence.
The sentence presents a list of three actions following the helping verb phrase 'are designed to'. The first two elements are the base verbs 'conserve' and 'reduce'.
Parallel structure requires that all items in a list or series share the same grammatical form.
2
Determine the grammatical form required for the blank.
To match the base verbs 'conserve' and 'reduce', the third element in the series must also be a base verb.
Using a non-base verb form would create faulty parallelism.
3
Select a base verb that logically fits the context of crop yields.
Verbs like 'maximize', 'increase', 'boost', 'improve', 'optimize', or 'enhance' fit both the grammatical constraint and the semantic context of agricultural productivity.
The correct word must be grammatically parallel and contextually logical.
