Question

Difficulty: HardWords in Context: High-Utility Vocabulary

Which choice completes the text with the most logical and precise word or phrase?

Answer:Traditional electrical grids are designed to handle maximum peak loads, meaning that auxiliary power plants must be constructed solely to meet demand during brief periods of extreme usage. By implementing smart grids that dynamically redistribute electricity in response to real-time consumption patterns, power grid engineers hope to 【obviate】 the necessity of building these underutilized facilities, thereby lowering infrastructure costs and reducing carbon emissions.

Answer

The correct answer is 'obviate' (or a synonym like 'eliminate' or 'preclude'), which means to anticipate and prevent or make unnecessary.
The correct answer is a word that means to make unnecessary or prevent, such as 'obviate', 'eliminate', or 'preclude'. The sentence explains that traditional grids require building auxiliary plants for peak usage, but smart grids dynamically redistribute electricity to manage peak usage, which makes building those extra facilities unnecessary.

Step-by-Step Solution

1
Analyze the context of the sentence to understand the relationship between smart grids and the construction of auxiliary power plants.
The text states that traditional grids require constructing auxiliary plants for brief peak periods, but smart grids dynamically redistribute electricity to manage peak usage.
This setup indicates that smart grids will make the construction of these extra plants unnecessary.
2
Identify the part of speech and semantic meaning required for the blank.
The blank follows 'to' and precedes 'the necessity', requiring a transitive verb in the base form that means 'to make unnecessary', 'to prevent', or 'to eliminate'.
This will precisely complete the logical flow of the sentence.
3
Determine high-utility vocabulary words that fit this meaning.
Words like 'obviate', 'eliminate', or 'preclude' fit the context perfectly, with 'obviate' being a highly precise academic term for making something unnecessary.
This satisfies both semantic precision and grammatical constraints.
