Difficulty: EasySupport and Cause-Effect Clues

Complete the sentence below by providing the word that best captures the cause-and-effect relationship established by the context clues.

Answer:Given that the city's newly constructed wetlands naturally filter urban runoff before it enters the bay, municipal water purity has consequently experienced a significant 【improvement】 over the past year.

Answer

improvement
The opening causal signal 'Given that' combined with the result adverb 'consequently' establishes that the natural filtration of urban runoff directly leads to better water quality. Therefore, a word meaning positive enhancement, such as 'improvement', correctly completes the logical cause-and-effect relationship.

Step-by-Step Solution

1
Identify the cause-and-effect signal words in the sentence.
The phrase 'Given that' establishes the cause (natural filtration of urban runoff), and 'consequently' introduces the direct effect on water purity.
Cause-and-effect transition signals indicate that the missing word must logically follow from the positive action described.
2
Determine the tone and direction required for the blank.
Because filtering runoff removes contaminants, the effect on water purity must be positive.
The blank requires a term that reflects a positive gain or enhancement in water quality.
