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.

[EX Q]: Passage: The term "Gadget" was a laboratory euphemism for a bomb, from which the laboratory's weapon physics division, "G Division", took its name in August 1944. At that time it did not refer specifically to the Trinity Test device as it had yet to be developed, but once it was, it became the laboratory code name. The Trinity Gadget was officially a Y-1561 device, as was the Fat Man used a few weeks later in the bombing of Nagasaki. The two were very similar, with only minor differences, the most obvious being the absence of fuzing and the external ballistic casing. The bombs were still under development, and small changes continued to be made to the Fat Man design.To keep the design as simple as possible, a near solid spherical core was chosen rather than a hollow one, although calculations showed that a hollow core would be more efficient in its use of plutonium. The core was compressed to prompt super-criticality by the implosion generated by the high explosive lens. This design became known as a "Christy Core" or "Christy pit" after physicist Robert F. Christy, who made the solid pit design a reality after it was initially proposed by Edward Teller. Along with the pit, the whole physics package was also informally nicknamed "Christy['s] Gadget".Of the several allotropes of plutonium, the metallurgists preferred the malleable δ phase. This was stabilized at room temperature by alloying it with gallium. Two equal hemispheres of plutonium-gallium alloy were plated with silver, and designated by serial numbers HS-1 and HS-2. The 6.19-kilogram (13.6 lb) radioactive core generated 15 W of heat, which warmed it up to about 100 to 110 °F (38 to 43 °C), and the silver plating developed blisters that had to be filed down and covered with gold foil; later cores were plated with nickel instead. The Trinity core consisted of just these two hemispheres. Later cores also included a ring with a triangular cross-section to prevent jets forming in the gap between them.
[EX A]: What is the code name of the device that was developed after it had a code name?

[EX Q]: Passage: Radiohead began work on their ninth studio album in September 2014, joined again by Godrich. In 2015 they resumed work in the La Fabrique studio near Saint-Rémy-de-Provence, France. The sessions were marred by the death of Godrich's father, and Yorke's separation from his wife, Rachel Owen, who died of cancer several months after the album's completion. In the same year, Yorke contributed a soundtrack, Subterranea, to The Panic Office, an installation of Radiohead artwork in Sydney, Australia, and Junun, a collaboration between Greenwood, Godrich, Israeli composer Shye Ben Tzur and Indian musicians, was released, accompanied by a documentary directed by Anderson. On Christmas Day 2015, Radiohead released a new song, "Spectre", on the audio streaming site SoundCloud. It had been commissioned for the 2015 James Bond film Spectre, but was rejected by the film producers as "too dark".Radiohead's ninth studio album, A Moon Shaped Pool, was released in May 2016 on Radiohead's website and online music stores, followed by retail versions in June via XL Recordings. It was promoted with music videos for the singles "Burn the Witch" and "Daydreaming", the latter directed by Anderson. The album includes several songs written years earlier, including "True Love Waits", and strings and choral vocals arranged by Jonny Greenwood and performed the London Contemporary Orchestra. It was Radiohead's sixth UK number-one album and reached number three in the US. It was the fifth Radiohead album nominated for the Mercury Prize, making Radiohead the most shortlisted act in the award's history, and was nominated for Best Alternative Music Album and Best Rock Song (for "Burn the Witch") at the 59th Annual Grammy Awards. It appeared on several publications' lists of the best albums of the year.
[EX A]: What is the name of the song that had a music video directed by Anderson?

[EX Q]: Passage: Construction of the cathedral began in about 1175, to the design of an unknown architect. Wells is the first cathedral in England to be, from its foundation, built in the Gothic style. According to art historian John Harvey, it is the first truly Gothic cathedral in the world, its architects having entirely dispensed with all the features that bound the contemporary east end of Canterbury Cathedral and the earlier buildings of France, such as the east end of the Abbey of Saint Denis, to the Romanesque. Unlike these churches, Wells has clustered piers rather than columns and has a gallery of identical pointed arches rather than the typically Romanesque form of paired openings. The style, with its simple untraceried lancet arches and convoluted mouldings, is known as Early English Gothic.From about 1192 to 1230, Adam Lock, the earliest architect at Wells for whom a name is known, continued the transept and nave in the same manner as his predecessor. Lock was also the builder of the north porch, to his own design.The Early English west front was commenced around 1230 by Thomas Norreys, with building and sculpture continuing for thirty years. Its south-west tower was begun 100 years later and constructed between 1365 and 1395, and the north-west tower between 1425 and 1435, both in the Perpendicular Gothic style to the design of William Wynford,  who also filled many of the cathedral's early English lancet windows with delicate tracery.
Between 1275 and 1310 the undercroft and chapter house were built by unknown architects, the undercroft in the Early English and the chapter house in the Geometric style of Decorated Gothic architecture. In about 1310 work commenced on the Lady Chapel, to the design of Thomas Witney, who also built the central tower from 1315 to 1322 in the Decorated Gothic style. The tower was later braced internally with arches by William Joy. Concurrent with this work, in 1329–45 Joy made alterations and extensions to the choir, joining it to the Lady Chapel with the retrochoir, the latter in the Flowing Decorated style.Later changes include the Perpendicular vault of the tower and construction of Sugar's Chapel, 1475–90 by William Smyth. Also, Gothic Revival renovations were made to the choir and pulpitum by Benjamin Ferrey and Anthony Salvin, 1842–57.
