In the following question the 1st and the last part of the sentence/passage are numbered 1 and 6. The rest of the sentence/ passage is split into four parts and named P, Q, R and S. These four parts are not given in their proper order. Read the sentence/passage and find out which of the five combinations is correct. 1 - The mayor walked up and down the vestibule of the hotel with his hands under his coat tails, as if he were merely seeking a cooler atmosphere than that of the room he had quitted. P - At length he went back to the door of the dining-room, paused, and found that the songs, toasts, and conversation were proceeding quite satisfactorily without his presence. Q - But there could be no doubt that he was in reality still possessed to the full by the new idea, whatever that might be. R - The Corporation, private residents, and major and minor tradesmen had, in fact, gone in for comforting beverages to such an extent that they had quite forgotten, not only the Mayor, but all those vast, political, religious, and social differences which they felt necessary to maintain in the daytime, and which separated them like iron grills. S - Seeing this the Mayor took his hat, and when the waiter had helped him on with a thin holland overcoat, went out and stood under the portico. 6 - Very few persons were now in the street; and his eyes, by a sort of attraction, turned and dwelt upon a spot about a hundred yards further down. ?

Option 4 : If statements I and II together are sufficient to answer the question.

Form statement I:

Day	Case I	Case II	Case III
Day	Person	Person	Person
Monday	A
Tuesday	E	A
Wednesday	F	E
Thursday		F	A
Friday	~~G, F~~	~~G, F~~	E
Saturday			F
Sunday	D	D	D

Hence, statement I alone is not sufficient to answer the question.

Form statement II:

Day	Case I	Case II
Day	Person	Person
Monday	G	B
Tuesday		B
Wednesday
Thursday
Friday
Saturday	B
Sunday	B	G

Hence, statement II alone is not sufficient to answer the question.

Form statement III:

Day	Case I	Case II	Case III	Case IV
Day	Person	Person	Person	Person
Monday	G
Tuesday		G
Wednesday			G
Thursday	F			G
Friday		F
Saturday			F
Sunday				F

Hence, statement III alone is not sufficient to answer the question.

On combining statements, I and II:

Day	Person
Monday	G
Tuesday	A
Wednesday	E
Thursday	F
Friday	C
Saturday	B
Sunday	D

Clearly, C’s exam was on Friday.

Hence, only statements I and II are sufficient to answer the question.
