Improve the bracketed part of the sentence.

 

When he arrived at the party, he (had been dressed) in a black suit.

 

There is no error in the sentence.

The given sentence is in simple present tense and states a general fact, hence the latter half of the sentence with the blank will also be in the simple present tense. Since the subject in the latter part of the sentence is singular .i.e. 'the number', the verb will be followed accordingly. Hence, option 4 is the correct answer.

The trick here is to follow the structure of the statement. The blank is followed by 'of' and thus the blank will take a filler that can be followed grammatically by 'of' and also manages to give a proper meaning. On the basis of these filters, none of the options except option 2 makes any sense.

'Cautious' can be used to make the sentence meaningful which means alert or be careful. The context of the statement is that of the monsoon season being a bit troublesome due to slippery roads which need to be navigated with care. 'Prepared' and 'smart' may appear to be true but we need to choose the most suitable response which in this case is 'cautious'. Hence, 'cautious' is the correct answer.

To settle a dispute, one needs to have a sound decision-making ability to be able to judge both the sides. Also, a judge is a free body to decide upon any issue. 'Know' is a verb which means to be aware of through observation, inquiry, or information. 'Tactics' refer to an action or strategy carefully planned to achieve a specific end. A judge doesn't need tactics to make a judgment. 'Discretion' means the freedom to decide what should be done in a particular situation. 'Brains' refer to the intellectual capacity. 'Bias' means inclination or prejudice for or against one person or group, especially in a way considered to be unfair. Hence option 3 is the correct response.

Judgement means the ability to make considered decisions or come to sensible conclusions. Progress means advancement. Policy means a strategy or an approach. Dissent means lack of approval. Action means activity. The Board members are usually involved in making decisions. Hence, a word that conveys the related meaning should be used to fill the blank. No other word except judgement makes sense in the given context. Hence, 'judgement' is the correct answer.

Clearly, only segment Q fits after the first segment. This eliminates all the options except 1.

Option 2: It is incorrect because it ends in S which ends in 'towards' which can't be used to any statement.

Option 3: It is incorrect for the same reason as option 2.

Option 4: 'towards their plight further worsened' makes no sense; hence it can be eliminated.

Option 5: R is a clear misfit after the first segment; hence it can also be eliminated. Hence, the correct sequence is QSRP.

'an' at the end of the first fixed segment indicates that Q, R and S can't follow the first segment. This leaves us with only one choice i.e. P. This eliminates options 2, 4, and 5.

There are only two such options: option A1and 3. Option 3 can be eliminated since part S ends with 'the' which can't be used as the end of the master statement. Hence, the correct sequence is PRSQ
