Complete the text with the most logical and precise word.

Answer:Some species of desert cacti have evolved highly specialized metabolic pathways that allow them to conserve water during periods of extreme drought. While these adaptations are highly beneficial in arid conditions, they can become 【detrimental】 when the plants are relocated to humid environments where excessive moisture can lead to root rot.

Answer

detrimental (or a synonym meaning harmful or disadvantageous)

The sentence sets up a contrast using the word 'While'. It states that the metabolic adaptations are 'highly beneficial' in dry environments but contrasts this with their effect in humid environments, where excessive moisture leads to 'root rot'. This negative outcome indicates that the adaptations become harmful or disadvantageous in humid settings, making 'detrimental' the most logical and precise choice.

Step-by-Step Solution

Analyze the sentence structure and transition words.

The word 'While' at the beginning of the sentence sets up a contrast between the cactus adaptations in two different environments.

This helps determine the relationship between the two clauses.

Evaluate the context clues in both parts of the sentence.

In arid conditions, the adaptations are described as 'highly beneficial'. In humid environments, the result is 'root rot' (a negative outcome).

This establishes that the missing word must have a negative connotation to contrast with 'beneficial'.

Select a precise, high-utility academic word that fits the context of causing harm or disadvantage.

The word 'detrimental' (or synonyms like 'deleterious' or 'counterproductive') logically completes the contrast.

It describes something that causes harm or damage, matching the negative consequence of root rot.
