instruction:
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.

Passage: The chain of craters has been the subject of several writers and naturalists. Mark Twain visited Mono Basin in the 1860s and wrote about Mono Lake, but did not mention any of the Mono–Inyo Craters except for the lake's two volcanic islands. He wrote in Roughing It (1872) that the lake was in a "lifeless, hideous desert ..." that was the "loneliest spot on earth ... little graced with the picturesque."
Naturalist John Muir explored the area in 1869. He described the "Mono Desert" as a "... country of wonderful contrasts. Hot deserts bounded by snow-laden mountains,—cinders and ashes scattered on glacier-polished pavements,—frost and fire working together in the making of beauty. In the lake are several volcanic islands, which show that the waters were once mingled with fire."  Muir described the Mono Craters as "... heaps of loose ashes that have never been blest by either rain or snow ..."In the spring of 1881 and the fall of 1882, geologist Israel Russell studied the area as a side-trip during his field research of Lake Lahontan, a now dry lake that covered much of nearby Nevada during the last glacial period. His Quaternary History of the Mono Valley (1889), which included a topographic survey by Willard D. Johnson, was the first thorough scientific description of Mono Lake and its volcanic features.
Russell named the Mono Craters and wrote: "The attention of every one who enters Mono Valley is at once attracted by the soft, pleasing colors of these craters as well as by the symmetry and beauty of their forms. They are exceptional features in the scenery of the region, and are rendered all the more striking by their proximity to the angular peaks and rugged outlines of the High Sierra.".
answer:
What is the name of the place that has two volcanic islands?

Passage: In the year 2074, the cybernetics market is dominated by two rival companies: USA's Pinwheel Robotics and Japan's Kobayashi Electronics. 'Cyborgs' are commonplace, used for anything from soldiers to prostitutes. Casella "Cash" Reese is a Pinwheel prototype cyborg developed for corporate espionage and assassination. She is filled with a liquid explosive called "Glass Shadow". Pinwheel's CEO, Martin Dunn, plans to eliminate the entire Kobayashi board of directors using Cash as a suicide bomber to precipitate a hostile takeover of the company and obtain a monopoly over the cyborg market.
Cash is programmed to mimic human senses and emotions such as fear, love, pain, and hate. Guided by Mercy, a renegade prototype cyborg who can communicate through any electronic device, Cash and her combat trainer Colton "Colt" Ricks escape the Pinwheel facility so Cash can avoid self-destruction, something that most corporate espionage cyborgs face. They're relentlessly pursued by Pinwheel's hired killer or "wiretapper", Daniel Bench.
Bench must also deal with a rival bounty hunter named Chen, who plans on killing Ricks and reprogramming Cash to have her blow up Pinwheel instead as a means to punish the company's director, Dunn, as reprisal for an earlier act from Dunn that displeased her. However, Chen and Ricks get into a fight, which results in Chen getting electrocuted by a fuse box.
answer:
Who is the head of the company that makes cyborgs filled with liquid explosive?

Passage: This was followed up by a group of scientists at the Collège de France in Paris: Frédéric Joliot-Curie, Hans von Halban, Lew Kowarski, and Francis Perrin. In February 1939, the Paris Group showed that when fission occurs in uranium, two or three extra neutrons are given off. This important observation suggested that a self-sustaining nuclear chain reaction might be possible. The term "atomic bomb" was already familiar to the British public through the writings of H. G. Wells, in his 1913 novel The World Set Free. It was immediately apparent to many scientists that, in theory at least, an extremely powerful explosive could be created, although most still considered an atomic bomb was an impossibility. Perrin defined a critical mass of uranium to be the smallest amount that could sustain a chain reaction. The neutrons used to cause fission in uranium are considered slow neutrons, but when neutrons are released during a fission reaction they are released as fast neutrons which have much more speed and energy. Thus, in order to create a sustained chain reaction, there existed a need for a neutron moderator to contain and slow the fast neutrons until they reached a usable energy level. The College de France found that both water and graphite could be used as acceptable moderators.Early in 1940, the Paris Group decided on theoretical grounds that heavy water would be an ideal moderator for how they intended to use it. They asked the French Minister of Armaments to obtain as much heavy water as possible from the only source, the large Norsk Hydro hydroelectric station at Vemork in Norway. The French then discovered that Germany had already offered to purchase the entire stock of Norwegian heavy water, indicating that Germany might also be researching an atomic bomb. The French told the Norwegian government of the possible military significance of heavy water. Norway gave the entire stock of 187 litres (41 imp gal; 49 US gal) to a Deuxième Bureau agent, who secretly brought it to France just before Germany invaded Norway in April 1940. On 19 June 1940, following the German invasion of France, it was shipped to England by the Earl of Suffolk and Major Ardale Golding, aboard the steamer Broompark. The heavy water, valued at £22,000, was initially kept at HM Prison Wormwood Scrubs, and was later secretly stored in the library at Windsor Castle. The Paris Group moved to Cambridge, with the exception of Joliot-Curie, who remained in France and became active in the French Resistance.
answer:
What country did heavy water come from?
