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.

Passage: During the First World War, a British officer - David Compton - on leave from the trenches in Paris falls in love with and has a liaison of three days with a French performing artist: Deloryse/Lola. He proposes to her and tells her to get ready for the wedding in an hour. He rushes to search for the English church. On the way he meets his superior, who tells him that he has to report immediately, they have to leave Paris. He doesn't even have the time to see his fiancé again.
After returning to fight on the front, he suffers from shellshock and forgets everything that happened in the last four years. After recovering he goes back to his wealthy life of rich industrialist, marries a British Socialite, with whom he runs entirely separate lives. She is the one to invite Deloryse to London to dance on one of her charity events. While dancing and singing on the stage she sees him in a loge. During her second number, where she sings the same song of when he met her in Paris, he finally has a flash back of the song and the singer. After the performance he sends her a notice that he wants to see her. She's very excited, but when Doctor Gavron comes to see her, he measures her pulse and tells her, that she has to give up the stage, as the strain might kill her, even if she dances once more. Then David comes. He meets her and his son Davey. But  he is now married to a British Socialite: Vesta Compton, who never wanted children, to the big regret of her husband. 
Question: What is the full name of the person who invites Deloryse to London?
Vesta Compton.

Passage: For the third time, the evil Wishmaster returns to wreck the lives of more innocents. This time, his victim is a beautiful, innocent and studious teenage girl named Diana Collins who accidentally opened up the Djinn's tomb (a strange box with a jewel inside) and released him. After gaining his freedom, the Djinn is asked by Professor Barash to let him be the one who makes the wishes. The professor wishes for two of the world's loveliest ladies to be in love with him.
However, as soon as the Djinn grants this wish, the women kill the professor; the Djinn takes the face off of the dead professor and is able to steal his identity. He then kills a secretary by her wishing for "files to burn up" but instead of the files, she burns. He takes the student file of Diana in an effort to find her and force her to fulfill her three wishes. While Diana is on the run, she must endeavor to prevent the Djinn from subjecting the entire world to Hell's wrath. While in a Church thinking it was safe, the Djinn is there instead of the priest. Her friend Ann, who is now the "professor's Teaching Assistant" makes the wish of "wanting to lose a little weight", to which she pukes up her guts in pain. Diana uses her first wish for her to stop having pain, but of course to the Djinn that means killing Ann. 
Question: What is the name of the person who has their identity stolen?
Barash.

Passage: The political and cultural impacts of the development of nuclear weapons were profound and far-reaching. William Laurence of The New York Times, the first to use the phrase "Atomic Age", became the official correspondent for the Manhattan Project in spring 1945. In 1943 and 1944 he unsuccessfully attempted to persuade the Office of Censorship to permit writing about the explosive potential of uranium, and government officials felt that he had earned the right to report on the biggest secret of the war. Laurence witnessed both the Trinity test and the bombing of Nagasaki and wrote the official press releases prepared for them. He went on to write a series of articles extolling the virtues of the new weapon. His reporting before and after the bombings helped to spur public awareness of the potential of nuclear technology and motivated its development in the United States and the Soviet Union.
The wartime Manhattan Project left a legacy in the form of the network of national laboratories: the Lawrence Berkeley National Laboratory, Los Alamos National Laboratory, Oak Ridge National Laboratory, Argonne National Laboratory, and Ames Laboratory. Two more were established by Groves soon after the war, the Brookhaven National Laboratory at Upton, New York, and the Sandia National Laboratories at Albuquerque, New Mexico. Groves allocated $72 million to them for research activities in fiscal year 1946–1947. They would be in the vanguard of the kind of large-scale research that Alvin Weinberg, the director of the Oak Ridge National Laboratory, would call Big Science.The Naval Research Laboratory had long been interested in the prospect of using nuclear power for warship propulsion, and sought to create its own nuclear project. In May 1946, Nimitz, now Chief of Naval Operations, decided that the Navy should instead work with the Manhattan Project. A group of naval officers were assigned to Oak Ridge, the most senior of whom was Captain Hyman G. Rickover, who became assistant director there. They immersed themselves in the study of nuclear energy, laying the foundations for a nuclear-powered navy. A similar group of Air Force personnel arrived at Oak Ridge in September 1946 with the aim of developing nuclear aircraft. Their Nuclear Energy for the Propulsion of Aircraft (NEPA) project ran into formidable technical difficulties, and was ultimately cancelled.The ability of the new reactors to create radioactive isotopes in previously unheard-of quantities sparked a revolution in nuclear medicine in the immediate postwar years. Starting in mid-1946, Oak Ridge began distributing radioisotopes to hospitals and universities. Most of the orders were for iodine-131 and phosphorus-32, which were used in the diagnosis and treatment of cancer. In addition to medicine, isotopes were also used in biological, industrial and agricultural research. 
Question: At what lab did a group of naval officers immerse themselves in nuclear energy research?

Oak Ridge.
