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: Brian, the head drilling engineer of an un-named company, sabotages the drilling operation as he is concerned that Alan the CEO is drilling too deep without taking necessary precautions.
Alan restarts the drilling operation on an island off the coast of China and while drilling using a mole like machine, the drilling team hits a magma flow which kills them. This then causes a large volcanic eruption and earthquake.
Alan and Brian start investigating the effects of the drilling, with help from Allison Saunders, head of research and development at the company. They realize that they have affected the stability of the Earth's core, which is going to cause natural disasters all over the world. They figure the only way to stop the magma flow and earthquakes is to use a series of nuclear explosions to reset the spinning of the Earth's core. They plan to drop these bombs using a new drilling machine.
The earthquakes start to spread all over the world, affecting major cities. Quito, Ecuador is hit and many important buildings are destroyed.
Darryl obtains the nuclear bombs from the Chinese government. However, they want their own team to do the drilling. Brian disagrees and assembles his own team including Allison and his drilling engineer colleges Brian and Rodney. Alan also volunteers to be part of the team.
They prepare to drill down into the earth to position the nuclear bombs at strategic positions ready for a coordinated sequence of explosions. They start drilling down into the ground, and successfully drop the first 2 nuclear bombs. They have an issue with the cabin pressure, but after running diagnostics they realize the sensors malfunctioned and they manage to reset them.
Answer:
What are the first names of the people who realize they have affected the stability of the Earth's core?
