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.

[Q]: Passage: The Rosetta Stone is listed as "a stone of black granodiorite, bearing three inscriptions ... found at Rosetta" in a contemporary catalogue of the artefacts discovered by the French expedition and surrendered to British troops in 1801. At some period after its arrival in London, the inscriptions on the stone were coloured in white chalk to make them more legible, and the remaining surface was covered with a layer of carnauba wax designed to protect the Rosetta Stone from visitors' fingers. This gave a dark colour to the stone that led to its mistaken identification as black basalt. These additions were removed when the stone was cleaned in 1999, revealing the original dark grey tint of the rock, the sparkle of its crystalline structure, and a pink vein running across the top left corner. Comparisons with the Klemm collection of Egyptian rock samples showed a close resemblance to rock from a small granodiorite quarry at Gebel Tingar on the west bank of the Nile, west of Elephantine in the region of Aswan; the pink vein is typical of granodiorite from this region.The Rosetta Stone is 1,123 millimetres (3 ft 8 in) high at its highest point, 757 mm (2 ft 5.8 in) wide, and 284 mm (11 in) thick. It weighs approximately 760 kilograms (1,680 lb). It bears three inscriptions: the top register in Ancient Egyptian hieroglyphs, the second in the Egyptian Demotic script, and the third in Ancient Greek. The front surface is polished and the inscriptions lightly incised on it; the sides of the stone are smoothed, but the back is only roughly worked, presumably because this would have not been visible when it was erected.
[A]: How many kilograms does the Rosetta Stone weigh?


[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.
[A]: What is the name of the song that had a music video directed by Anderson?

However, Glure is jealous of Lad's success and has rigged one event to have such specialized rules that he believes only his recently purchased high-priced, English-trained collie can win. During the competition, which involves directing the dogs through a tricky set of a maneuvers, Lad is able to complete the course, while Glure's champion does not recognize the hand signals Glure makes while holding a cigar.

Her nurse initially does not see the snake, and begins beating Lad for "attacking" the little girl. Distraught, Angela stands and walks for the first time since her illness to stop the nurse's abuse of her friend. Lad disappears for three days, reappearing covered in mud but cured of the poison.
