Directions: Fill in the blanks with the appropriate pair of words to make the sentence a meaningful one. Each sentence is followed by five pairs of words. Choose the correct pair.

The trade union _____ the role of the management in ending the strike, claiming that they had ____ the problem.

The sentence can either be positive or negative. For this a pair of negative or positive words is required. If we use praised or endorsed or appreciated, no corresponding positive word is there among the choices. With criticised, we do not have a corresponding negative word in ‘pacified’. So, we have to use negative pair of words, which is found in option 1.
