Question: Paragraph- Sent 1: When he was at Oxford he had been well known for concealing under a slightly rowdy exterior the highest spirits of any of the undergraduates.
Sent 2: He was looked upon as the most fascinating of _farceurs_.
Sent 3: It seems that he had distinguished himself there less for writing Greek verse, though he was good at it, than for the wonderful variety of fireworks that he persistently used to let off under the dean's window.
Sent 4: It was this fancy of his that led, first, to his popularity, and afterwards to the unfortunate episode of his being sent down; soon after which he had married privately, chiefly in order to send his parents an announcement of his wedding in _The Morning Post_, as a surprise.
Sent 5: Some people had come in after dinner--for there was going to be a little _sauterie intime_, as Mrs Mitchell called it, speaking in an accent of her own, so appalling that, as Vincy observed, it made it sound quite improper.
Sent 6: Edith watched, intensely amused, as she saw that there were really one or two people present who, never having seen Mitchell before, naturally did not recognise him now, so that the disguise was considered a triumph.
Sent 7: There was something truly agreeable in the deference he was showing to a peculiarly yellow lady in red, adorned with ugly real lace, and beautiful false hair.
Sent 8: She was obviously delighted with the Russian prince.
Question: What caused the individual in Sentence 4 to be "sent down"? (A) Married Privately (B) Wonderful Variety of Fireworks (C) Lighting fireworks under Dean's window.

Answer: B, C.

Question: Paragraph- Sent 1: He read the telegram again.
Sent 2: In desperation he went back to the long distance booth, but found the line still out of order, and a wire had come giving the details of the damage done by the storm.
Sent 3: It would be several days before communication could be established.
Sent 4: There was no help coming from headquarters, and from the wording of the telegram there seemed to be a reason for their not giving clear details.
Sent 5: He must get a copy of the paper.
Sent 6: Reluctantly he went to the printing office and made known his errand.
Sent 7: Mr. Driggs was delighted to give him the paper--he had it some place, though he very seldom opened any of his exchanges.
Sent 8: He evidently bore Mr. Steadman no ill-will for his plain talk two weeks ago.
Sent 9: With some difficulty he found it, with its wrapper still intact.
Sent 10: It was a loose wrapper, which slipped off and on easily.
Sent 11: Mr. Steadman remarked carelessly that there was an editorial in it to which his attention had been drawn, on hearing which Mr. Driggs turned his head and winked at an imaginary accomplice.
Question: What was out of order that would take several days to get back online? (A) The booth's line (B) The telephone (C) The phones.

Answer:
A.
