Passage: Josh and Dinah Barkley (Fred Astaire and Ginger Rogers) are a husband-and-wife musical comedy team at the peak of their careers. After finishing a new show, Dinah meets serious French playwright Jacques Pierre Barredout, who suggests that Dinah should take up dramatic acting. Dinah tries to keep the suggestion a secret from Josh, but when he finally discovers Dinah hiding a script for Jacques' new show from him, the couple splits up.
Their good friend, acerbic composer Ezra Miller tries to trick them back together again, but fails. When Josh secretly watches Dinah's rehearsals for Barredout's new play and sees how she is struggling, he calls her up and pretends to be the Frenchman, giving her notes that help her to understand her part, the young Sarah Bernhardt. As the result, Dinah gives a brilliant performance. After the show, she accidentally learns that her late-night mentor was Josh and not Barredout, so she rushes to Josh's apartment and the two reconcile.
Question: What is the last name of the late-night mentor?
Barkley.

Passage: After her husband Martin completes a four-year prison sentence for insider trading, Emily Taylor drives into a wall in an apparent suicide attempt. Jonathan Banks, her assigned psychiatrist, prescribes a series of antidepressants, but none work. Jonathan contacts Emily's previous psychiatrist, Victoria Siebert, who suggests an experimental new drug, Ablixa. The drug seems to help Emily, but gives her sleepwalking episodes as a side effect.
One night, Emily stabs Martin to death while sleepwalking. Jonathan fights for Emily's acquittal in court. She pleads insanity and is declared not guilty on the condition that she stays in a psychiatric hospital until cleared by Jonathan. The publicity destroys Jonathan's reputation, and his colleagues assume negligence on his part.
Jonathan discovers evidence that Emily is lying; she was not depressed and faked her suicide attempts. He also discovers someone may have profited from Ablixa's fall in stock value. He interviews Emily after administering what he claims is a truth serum that will make her drowsy. Though the serum is actually saline water, she feigns drowsiness, confirming Jonathan's suspicion that she is deceiving him. When he confronts Victoria with his findings, she mails photographs to his wife Deirdre implying he had an affair with Emily. Deirdre leaves him, taking her son with her.
Question: What is the full name of the person who begins sleepwalking?
Emily Taylor.

Passage: The party turned for home after 73 days' southward travel. Rations had been cut several times to extend the return journey time beyond the original 110-day estimate. Shackleton now aimed to reach Hut Point in 50 days, since according to Shackleton's prior orders Nimrod, having returned to take the expedition home, would depart on 1 March at the latest. The four men were now much weakened, yet in the following days they achieved impressive distances, reaching the head of the glacier on 19 January. As they began the descent they had five days' food at half rations, to last them until the Lower Glacier depot; during the ascent the same distance had taken 12 days. Shackleton's physical condition was by now a major concern, yet according to Adams "the worse he felt, the harder he pulled".The depot was reached on 28 January. Wild, ill with dysentery, was unable to pull or to eat anything but biscuits, which were in short supply. On 31 January Shackleton forced his own breakfast biscuit on Wild, a gesture that moved Wild to write: "BY GOD I shall never forget. Thousands of pounds would not have bought that one biscuit". A few days later, the rest of the party were struck with severe enteritis, the result of eating tainted pony-meat. But the pace of march had to be maintained; the small amounts of food carried between depots would make any delay fatal. However, a strong wind behind them enabled them to set a sail on the sledge and maintain a good marching rate.
"We are so thin that our bones ache as we lie on the hard snow", wrote Shackleton. From 18 February onward they began to pick up familiar landmarks, and on the 23rd they reached Bluff Depot, which to their great relief had been copiously resupplied by Ernest Joyce. The range of delicacies over and above the crates of regular supplies was listed by Shackleton: "Carlsbad plums, eggs, cakes, plum pudding, gingerbread and crystallised fruit". Wild's laconic comment was "Good old Joyce".Their food worries were now resolved, but they still had to get back to Hut Point before the 1 March deadline. The final leg of their march was interrupted by a blizzard, which held them in camp for 24 hours. On 27 February, when they were still 33 nautical miles (61 km; 38 mi) from safety, Marshall collapsed. Shackleton then decided that he and Wild would make a dash for Hut Point in hopes of finding the ship and holding her until the other two could be rescued. They reached the hut late on 28 February. Hoping that the ship was nearby, they sought to attract its attention by setting fire to a small wooden hut used for magnetic observations. Shortly afterwards Nimrod, which had been anchored at the Glacier Tongue, came into view: "No happier sight ever met the eyes of man", wrote Wild later. It was a further three days before Adams and Marshall could be picked up from the Barrier, but by 4 March the whole southern party was aboard and Shackleton was able to order full steam towards the north.
Question: What was the full name of the person who gave Shackleton crystallised fruit?
Ernest Joyce.
