Difficulty: EasyWords in Context: High-Utility Vocabulary

Which word completes the text with the most logical and precise meaning?

Answer:Although many desert plants rely on deep root systems to access water stored far underground, some species have adapted to absorb moisture directly from the air. For these species, morning fog represents a vital resource that helps 【ensure】 their survival during long periods of drought.

Answer

ensure (or a logically precise synonym such as sustain, secure, maintain, guarantee, support, or enable)
The text describes morning fog as a 'vital resource' that plays a positive role for desert plants during a drought. Therefore, the word in the blank must mean to guarantee, keep in existence, or make certain. Words such as 'ensure,' 'sustain,' 'secure,' 'maintain,' or 'support' are logically and grammatically precise in this context.

Step-by-Step Solution

1
Analyze the context of the sentence containing the blank.
The text states that morning fog is a 'vital resource' that 'helps' the plants during 'long periods of drought.'
Understanding the surrounding words allows us to determine the relationship between the fog and the plants' survival.
2
Identify the semantic role required for the missing word.
Because fog is a positive and essential resource during a dry period, the missing word must mean to make certain, protect, or keep in existence.
The blank must logically link a vital resource to the continuation of the plants' lives.
