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.

Let me give you an 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.
The answer to this example can be: Who believes Fagin's gang make wallets and handkerchiefs?.
Here is why: 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.

OK. solve this:
Passage: H. L. Hunley takes his ship, the H.L. Hunley, out in the Charleston, South Carolina  harbor and it sinks with all hands. As the blockade still needs to be broken, Brig. Gen. P. G. T. Beauregard has the ship raised and puts George E. Dixon in charge. He starts looking for a crew and after some difficulty finally finds enough volunteers to man it. They practice cranking the propeller. The crew do not all get along with each other. Dixon flashes back to the Battle of Shiloh, where a gold coin given to him by his wife (who was later killed in a steamboat explosion caused by a drifting mine) deflected a bullet and saved his life. They take the ship down and sit on the bottom to see how long they can stay down and almost get stuck. The U.S. Navy is warned about the sub. The crew votes that if after an attack they are stuck on the bottom, they will open the valves, flooding the ship, rather than suffocate. They go out to attack the USS Wabash, but the attack fails. Following the warning the ship has draped metal chain netting over the side. Also the rope which was attached to the torpedo they were to release under the ship gets loose and becomes entangled in the propeller. It has to be cut loose while sailors on the Wabash shoot at the Hunley. Beauregard proposes putting the torpedo at the end of a long spar. The USS Housatonic is ordered to change its position in the harbor and always be ready to steam, meaning it cannot hang metal netting over the side. The Hunley's second in command, Lt. Alexander, is ordered to Mobile, Alabama, and a young soldier who had been volunteering to join the crew is allowed to do so.
Answer:
What is the name of the object raised by Brig. Gen. P.G.T. Beauregard?
