Since, the starting statement carries a subject; R will be the first statement. The next statement describes why are they hunted, so Q follows P, as it states that what is being done with the horns. S would be the concluding statement and thus form a coherent paragraph.

The correct formation would be, ‘The Rhinoceros is hunted by poachers for its horn which is sold at high prices.’

Since, the sentence starts with a subject, the next statement will carry a relative pronoun connecting the statements. S follows the opening statement. P will be the next statement which is mentioning the other feature of the man. Q will be the next statement as it describes another quality of man. Thus, R will be the concluding statement and thus form a coherent paragraph.

The correct formation would be, ‘The man who can play most heartily when he has the chance of playing is generally the one who can work very hard when he must work’.

Since, the sentence starts talking about the thought process, R will be the next statement as it is talking about the two factors. Q will be the continuing statement as it carries a relative pronoun which connects both the statement. S follows Q as it discusses the need for a language and P discusses why there is a need for the international language.

The correct formation would be, ‘We can think of two factors which suggest the need for an international language often confused in the public mind’.

Since, the sentence starts talking about the leader of the opposition, the connecting statement will be R as it carries a relative pronoun ‘who’ which relates the sentences. S follows as it states the disappointment of the leader and the next statement talked about the reason of disappointment. P would be the concluding statement as it goes with the flow describing how the leader decided to convince the assembly and thus makes a coherent paragraph.

The correct formation would be, ‘The leader of the opposition who had a reputation for speech making was very much disappointed on realising that he had failed to convince the assembly in the manner he had planned to convince them’.

Since, the sentence starts talking about the forces, the continuing statement would be the statement talking about the consensus of the forces on a particular point i.e. Q follows. R will be the next statement as it connects Q by stating that they agreed for a cease fire. The next statement would be talking about the reason of the cease fire, therefore, P follows and S would be the concluding statement which makes a coherent paragraph. The correct formation would be, ‘Georgian loyalists and rebel forces agreed to a ceasefire today after a week of fighting in which 51 people were killed’.

The phrase ‘that he could not serve’ is grammatically correct. This is because other forms of verb doesn’t go with the blank and this form of verb is grammatically and contextually correct. Thus, the correct formation would be, ‘He was too conscientious in the discharge of his duties to serve that exploiter for long’.
