[EX Q]: Passage: While Stafford was still working for Dorsey, Johnny Mercer told her, "Some day I'm going to have my own record company, and you're going to record for me." She subsequently became the first solo artist signed to Capitol after leaving the Pied Pipers in 1944. A key figure in helping Stafford to develop her solo career was Mike Nidorf, an agent who first heard her as a member of the Pied Pipers while he was serving as a Captain with the United States Army. Having previously discovered artists such as Glenn Miller, Artie Shaw, and Woody Herman, Nidorf was impressed by Stafford's voice, and contacted her when he was demobilized in 1944. After she agreed to let him represent her, he encouraged her to reduce her weight and arranged a string of engagements that raised her profile, and confidence.The success of Stafford's solo career led to a demand for personal appearances, and from February 1945 she embarked on a six-month residency at New York's La Martinique nightclub. Her performance was well-received—an article in the July 1945 edition of Band Leaders magazine described it as "sensational"—but Stafford did not enjoy singing before live audiences, and it was the only nightclub venue she ever played. Speaking about her discomfort with live performances, Stafford told a 1996 interview with The New Yorker's Nancy Franklin, "I'm basically a singer, period, and I think I'm really lousy up in front of an audience—it's just not me."Stafford's tenure with the United Service Organizations (USO) during World War II—which often saw her perform for soldiers stationed in the U.S.—led to her acquiring the nickname "G.I. Jo". On returning from the Pacific theater, a veteran told Stafford that the Japanese would play her records on loudspeakers in an attempt to make the U.S. troops homesick enough to surrender. She replied personally to all the letters she received from servicemen. Stafford was a favorite of many servicemen during both World War II and the Korean War; her recordings received extensive airplay on the American Forces radio and in some military hospitals at lights-out. Stafford's involvement with servicemen led to an interest in military history and a sound knowledge of it. Years after World War II, Stafford was a guest at a dinner party with a retired naval officer. When the discussion turned to a wartime action off Mindanao, the officer tried to correct Stafford, who held to her point. He countered her by saying, "Madame, I was there". A few days after the party, Stafford received a note of apology from him, saying he had re-read his logs and that she was correct. 
Question: What two wars was Stafford a favorite of many of the servicemen?
[EX A]: World War II.

[EX Q]: Passage: Her pregnant mother is in labor and in dire need of a doctor, but young Emily Dunning is new to the neighborhood and knows no one. When someone finally suggests a Dr. Yeomans, she is shocked to discover the doctor is a woman. It is the turn of the century in New York and times are changing, but as yet women are not being made welcome in the field of medicine. Emily is so impressed by Marie Yeomans that she decides to enroll in med school at Cornell.
Fellow student Ben Barringer is one of the few there who encourage Emily, and they also fall in love. Ben plans to continue his education at Harvard, but upsets Emily by asking her to abandon her studies and accompany him. Emily instead moves to New York, where she and Dr. Yeomans share an apartment. Hospitals deny her an internship until a reluctant Dr. Seth Pawling is persuaded to accept her, although he confines her mainly to ambulance duty. Ben, it turns out, has become an intern at the same hospital.
A patient is pronounced dead prematurely by a Dr. Graham, but is resuscitated by Emily, who exhausts herself for hours in the process. A nurse informs the press of Emily's heroic act, irritating Graham but impressing Pawling, who recognizes her determination and skills. When a typhoid epidemic breaks out, the need for doctors is so great that Dr. Yeomans is asked to help. She, too, earns the respect of the hospital's men, just before her weak heart gives out. Ben is leaving for Paris to continue his work, but Emily heeds her friend's advice to have a personal life as well as a professional one, so she promises Ben that their careers will not keep them apart. 
Question: What is the name of the woman that enrolls in med school at Cornell?
[EX A]: Emily Dunning.

[EX Q]: Passage: While Pei and Musho were coordinating the Dallas project, their associate Henry Cobb had taken the helm for a commission in Boston. John Hancock Insurance chairman Robert Slater hired I. M. Pei & Partners to design a building that could overshadow the Prudential Tower, erected by their rival.After the firm's first plan was discarded due to a need for more office space, Cobb developed a new plan around a towering parallelogram, slanted away from the Trinity Church and accented by a wedge cut into each narrow side. To minimize the visual impact, the building was covered in large reflective glass panels; Cobb said this would make the building a "background and foil" to the older structures around it. When the Hancock Tower was finished in 1976, it was the tallest building in New England.
Serious issues of execution became evident in the tower almost immediately. Many glass panels fractured in a windstorm during construction in 1973. Some detached and fell to the ground, causing no injuries but sparking concern among Boston residents. In response, the entire tower was reglazed with smaller panels. This significantly increased the cost of the project. Hancock sued the glass manufacturers, Libbey-Owens-Ford, as well as I. M. Pei & Partners, for submitting plans that were "not good and workmanlike". LOF countersued Hancock for defamation, accusing Pei's firm of poor use of their materials; I. M. Pei & Partners sued LOF in return. All three companies settled out of court in 1981.The project became an albatross for Pei's firm. Pei himself refused to discuss it for many years. The pace of new commissions slowed and the firm's architects began looking overseas for opportunities. Cobb worked in Australia and Pei took on jobs in Singapore, Iran, and Kuwait. Although it was a difficult time for everyone involved, Pei later reflected with patience on the experience. "Going through this trial toughened us," he said. "It helped to cement us as partners; we did not give up on each other.". 
Question: Whose rival erected the Prudential Tower?
[EX A]:
I. M. Pei & Partners.
