In this task, you're expected to write answers to questions involving multiple references to the same entity. The answer to the question should be unambiguous and a phrase in the paragraph. Most questions can have only one correct answer.

Example Input: Passage: After thief Alex Cardo gets caught and betrayed by his partner in crime John while stealing an ancient Jian in Thailand, he soon finds himself imprisoned and beaten. One of the guards, Demon, is particularly upset by Alex's appearance and tortures him whenever he gets the opportunity. Alex finds one friend and mentor in the jailhouse, Master Sun, who teaches him a superior fighting style called "Iron Hand". When a "best of the best kumite" is to take place, Demon gets an invitation. Now Master Sun and Alex need to find a way to let Alex take part in the kumite, too.
The final fight pits Alex and Demon together.  At first, and for a long time, Demon has the upper hand in terms of strength and fighting ability.  When Alex is down, he takes one last look at Master Sun and uses the "Iron Hand" against his opponent, severely damaging and defeating Demon.  Alex is the winner, and as part of deals previously made, Master Sun is freed from prison, and so is Alex. 
Question: What is the full name of the person who learns the "Iron Hand" fighting style?
Example Output: Alex Cardo.

Example Input: Passage: Sometime after 4 p.m. on December 6, 1989, Marc Lépine arrived at the building housing the École Polytechnique, an engineering school affiliated with the Université de Montréal, armed with a semi-automatic rifle and a hunting knife. Lépine purchased a rifle on November 21, 1989, in a Checkmate Sports store in Montreal. He had told the clerk that he was going to use it to hunt small game. Lépine had been in and around the École Polytechnique building at least seven times in the weeks leading up to December 6.
Lépine first sat in the office of the registrar on the second floor for a while. While there, he was seen rummaging through a plastic bag. He did not speak to anyone, even when a staff member asked if she could help him. Lépine left the office and was subsequently seen in other parts of the building before entering a second-floor mechanical engineering class of about sixty students at about 5:10 p.m. After approaching the student giving a presentation, he asked everyone to stop everything and ordered the women and men to opposite sides of the classroom. No one moved at first, believing it to be a joke until he fired a shot into the ceiling.Lépine then separated the nine women from the approximately fifty men and ordered the men to leave. He asked the remaining women whether they knew why they were there, and when one student replied "no," he answered: "I am fighting feminism." One of the students, Nathalie Provost, said, "Look, we are just women studying engineering, not necessarily feminists ready to march on the streets to shout we are against men, just students intent on leading a normal life." Lépine responded, "You're women, you're going to be engineers. You're all a bunch of feminists. I hate feminists." He then opened fire on the students from left to right, killing six, and wounding three others, including Provost.  Before leaving the room, he wrote the word shit twice on a student project.Lépine continued into the second-floor corridor and wounded three students before entering another room where he twice attempted to shoot a female student. When his weapon failed to fire, he entered the emergency staircase where he was seen reloading his gun. He returned to the room he had just left, but the students had locked the door; Lépine failed to unlock it with three shots fired into the door. Moving along the corridor, he shot at others, wounding one, before moving towards the financial services office where he shot and killed a woman through the window of the door she had just locked. 
Question: What is the last name of the person who did not speak to anyone when a staff member asked if they could help him?
Example Output: Lépine.

Example Input: Passage: Stanford did not employ a full-time professor in religion until 1951 and did not establish a religious studies department until 1973, later than most other universities in the U.S.  Earlier courses in religion were largely offered by the chaplains of Stanford Memorial Church.  David Charles Gardner offered a course in Biblical history and literature beginning in 1907, and by 1910, he was teaching New Testament Greek and Bible classes.  Gardner's successor, D. Elton Trueblood, whose goal was the establishment of a non-denominational graduate school in religious studies at Stanford, taught classes about the philosophy of religion.  In 1941 Trueblood's efforts to expand the study of religion resulted in the creation of a minor in religion, as well as twenty-one courses offered by him and four faculty members.  By 1960, the chaplains of Stanford Memorial Church no longer had to run the program, which had expanded to allow students the option of majoring in the study of religion.  By the mid-1960s, the religious studies program at Stanford was enjoying "enormous success".In the 1960s, the study of religion at Stanford began to focus more on social and ethical issues like race and the Vietnam War.  Leading this focus was Stanford Memorial Church Dean of the Chapel and Professor of Religion B. Davie Napier, who was "a powerful critic of U.S. policy in Vietnam".  Napier, along with Stanford professors Michael Novak and Robert McAfee Brown, who had previously been faculty members of seminaries, were the subject of a Time Magazine article in 1966, describing "the renaissance of faith and learning at Stanford".  Students crowded into the church to hear anti-war speeches by them, as well as by "notables" such as Linus Pauling and William Sloan Coffin.  Harvey credited Napier for making the church a popular meeting place on campus for undergraduates and for turning it into "Christian theater—the introduction of jazz and other types of experimental worship as well as provocative preaching".Stanford University was the first major educational institution in the United States that conducted same-sex commitment ceremonies at its chapel.  Its first ceremony was held in 1993, and was officiated by Associate Dean Diana Akiyama.  In 2017, a campus organization attempted to have Stanford Memorial Church declared a sanctuary church for the undocumented immigrant student population, but was unsuccessful due to university policies regarding the status of the church as part of the university. 
Question: What is the full name of the person Trueblood replaced?
Example Output:
David Charles Gardner.
