In the question, a small paragraph is given with four highlighted words. You have to identify the highlighted word is correct used on its position or not. Mark an incorrectly used word
Electricity generation costs are rising by 30% every year in India but power utilities are not being permitted to preserve consumer charges. The challenge will be to end this chiaroscuro effect where one part of the country glows but the other plunges into an area of darkness
The context of the sentence talks about to review or amend consumer charges as the cost of generating electricity is rising. ‘Preserve consumer charges’ is opposite to the context of the sentence. ‘Revise’ or ‘Review’ is the correct word. So, ‘preserve; is incorrect here ‘Utilities’ – a service that is used by the public ‘Preserve’ – maintain in its original or existing state ‘Chiaroscuro’ – an effect of contrasted light and dark ‘Plunges’ – push or thrust quickly
