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: Electra Heart debuted at number one on the UK Albums Chart with first-week sales of 21,358 copies. It became Diamandis' first chart-topping album in the United Kingdom, although it was additionally distinguished as the lowest-selling number-one record of the 21st century in the country. It was later surpassed by Write It on Your Skin by Newton Faulkner, which debuted at number one on the UK Albums Chart with first-week sales of 16,647 copies three months later. On 15 April 2016, Electra Heart was certified gold by the British Phonographic Industry for exceeding shipments of 100,000 units in the United Kingdom. The record additionally reached number one on both the Irish Albums Chart and the Scottish Albums Chart; it was recognised with a gold certification in the former territory by the Irish Recorded Music Association (IRMA).Electra Heart performed moderately on additional record charts in Europe. The record peaked at number 11 on the Swiss Hitparade, and reached number 17 on the German Media Control Charts. It charted at number 25 on the O3 Austria Top 40, number 30 on the Norwegian VG-lista, and number 41 on the Swedish Sverigetopplistan. The album reached the lower ends of the Dutch MegaCharts and the Belgian Ultratop in Wallonia, respectively peaking at numbers 92 and 132 in each region. However, it reached number 31 on the Official New Zealand Music Chart and number 32 on the Australian ARIA Albums Chart in Oceania.Electra Heart debuted at number 31 on the US Billboard 200, and reached number two on the Billboard Dance/Electronic Albums component chart. It had sold 150,000 copies in the United States as of May 2015. On 13 April 2019, the album was certified gold by the Recording Industry Association of America (RIAA), denoting shipments in excess of 500,000 units in the United States. Elsewhere in North America, the record peaked at number 50 on the Canadian Albums Chart. In August 2012, Diamandis commented that she believed consumers in the United Kingdom had misinterpreted her comical effort with a perceived abandonment of her original musical inspiration, thus resulting in a relative underperformance in the country. In contrast, she felt that her American audience was more receptive of Electra Heart and her evolving public image.As of 2015, three million singles had been sold from Electra Heart.
What is the name of the artist that had their album be certified gold on 15 April 2016?

Passage: An inventory of medium and large mammals in the park confirmed the presence of 30 species in Saguaro National Park between 1999 and 2008. Of these, 21 were found in the Tucson Mountain District and 29 in the Rincon Mountain District. A partial list of the park's mammals includes cougars, coyotes, bobcats, white-tailed deer, mule deer, javelinas, gray foxes, black-tailed jackrabbits, desert cottontails, ring-tailed cats, white-nosed coatis, ground squirrels, and packrats. One endangered mammal, the lesser long-nosed bat, lives part of the year in the park and part of the year in Mexico.The wide range of habitats in the park supports a diverse population of birds including some, such as the vermilion flycatcher and the whiskered screech owl, uncommon elsewhere in the United States. Among the park's 107 bird species are great horned owls, cactus wrens, ravens, kestrels, turkey vultures, roadrunners, woodpeckers, hawks, quails, and hummingbirds, and one threatened species, the Mexican spotted owl.The park's 36 reptile species include desert tortoises, diamondback rattlesnakes (one of the more commonly seen snakes), coral snakes, Gila monsters, short-horned lizards, spiny lizards, and zebra-tailed lizards. Despite the aridity, three amphibian species inhabit the park: the canyon tree frog, the lowland leopard frog, and Couch's spadefoot, which lives in underground burrows, emerging to breed during summer rains. Forest fires, which create erosion-prone burned areas, have destroyed many of the leopard frog's breeding pools, which fill with sediment. The Arizona Game and Fish Department lists the lowland leopard frog as a species of special concern.Urban sprawl, air and water pollution, noise, light pollution, and a range of habitat restricted by human infrastructure put stress on the park's mammals and other animals, but the most serious immediate threat to them is roadkill. About 50,000 vertebrates a year die on the park's roads when they are hit by a vehicle. The Rincon Mountain District has few roads, but Picture Rocks Road, an eastwest commuter highway crossing the Tucson Mountain District, is highly dangerous to wildlife. Attempts in 2002 to convert it to a hiking trail failed after the proposal met with stiff public resistance.
What was attempted to be converted into a hiking trail?

Passage: Anthony Anthony has been identified as the compiler of the information and the artist behind the illustrations through his signature, which has been compared with holograph letters among the State Papers. Anthony's father was William Anthony (died 1535) a Fleming from Middelburg in Zeeland who migrated to England in 1503. William was a supplier of beer to the army, and Anthony followed in his father's footsteps. He went into beer exporting no later than 1530 and became a supplier of beer to the navy. In 1533 Anthony was appointed gunner at the Tower of London, a position he retained nominally until his death. He rose to the rank of overseer of the Ordnance Office, the government body responsible for supplying the armed forces with artillery, and it was in this position that he compiled his Roll. In 1549 he was promoted to master surveyor of the ordnance in the Tower, Calais, Boulogne, and elsewhere for life. He continued the work of supplying arms to English forces, and was active in the last month of his life supplying guns for an expedition against Le Havre.In 1939 Dutch historian Nicholas Beets proposed that the Flemish artist and cartographer Cornelis Antoniszoon (or Antonisz., c. 15071553) could have been Anthony Anthony's brother. Although Beets' suggestion of kinship was conjectural and without any direct evidence, it was picked up by Geoffrey Callender in the Mariner's Mirror in 1963 and has been relayed by several other authors. The will of William Anthony did not mention any other sons and Anthonisz. is believed to have been the son of Antonis Egbertson, the daughter of Jacob Corneliszoon van Oostzanen. That Cornelis and Anthony were related is, in the words of Ann Payne, "not, presumably, impossible, but there is little evidence that they were connected at all".
What is the full name of the person that was appointed gunner at the Tower of London?
