Given the task definition, example input & output, solve the new input case.
In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
Example: Passage: Nearing London, Oliver encounters Jack Dawkins, a pickpocket more commonly known by the nickname the "Artful Dodger", and his sidekick, a boy of a humorous nature named Charley Bates, but Oliver's innocent and trusting nature fails to see any dishonesty in their actions. The Dodger provides Oliver with a free meal and tells him of a gentleman in London who will "give him lodgings for nothing, and never ask for change". Grateful for the unexpected assistance, Oliver follows the Dodger to the "old gentleman's" residence. In this way Oliver unwittingly falls in with an infamous Jewish criminal known as Fagin, the gentleman of whom the Artful Dodger spoke. Ensnared, Oliver lives with Fagin and his gang of juvenile pickpockets in their lair at Saffron Hill for some time, unaware of their criminal occupations. He believes they make wallets and handkerchiefs.
Output: Who believes Fagin's gang make wallets and handkerchiefs?.
This question is based on the following sentence in the passage "He believes they make wallets and handkerchiefs". It evaluates the understanding that the pronoun "he" refers to name "Oliver". You can ask questions like this one about most pronouns in a paragraph.

New input case for you: Passage: Mark Bradley is a radio commentator whose pilot, Joe Walker, is flying him across the South Pacific to a conference in Australia. 
Engine trouble develops, and Walker must make a forced landing on the beach of a small, uncharted island inhabited by Dr. Paul Lujan. On the island with Lujan are his three naive daughters, who have never known another man except their father. 
Lujan, unfriendly to the point of hostility, orders the intruders to leave his island, but one of their aircraft's two engines is too badly damaged for them to be able to comply without first making repairs. He grants them a couple days in order to do so. In the meantime he grudgingly introduces Bradley and Walker to his trio of young, beautiful daughters, Venus, Urana, and Mercuria. The two men soon learn that Dr. Lujan was an atomic scientist who fled the civilized world with his family because he fears the havoc being caused by the discovery of nuclear energy.
To the doctor's disapproval, his two older daughters easily fall in love with the two attractive strangers and try to help them, while the third, 16 and jealous of her sisters, tries to foil their plans. This forces them to make a choice between staying on the island with their father or returning with the two men to a civilization they have only experienced via short wave radio broadcasts. When Bradley mentions that he plans on doing a radio broadcast about Lujan and his island location after he returns to civilization, the Dr. begins to scheme a way to keep the men and his daughters on the island.
Output:
What is the full name of the person being flown across the South Pacific?
