Passage: The spotted green pigeon or Liverpool pigeon (Caloenas maculata) is a species of pigeon which is most likely extinct. It was first mentioned and described in 1783 by John Latham, who had seen two specimens of unknown provenance and a drawing depicting the bird. The taxonomic relationships of the bird were long obscure, and early writers suggested many different possibilities, though the idea that it was related to the Nicobar pigeon (C. nicobarica) prevailed, and it was therefore placed in the same genus, Caloenas. Today, the species is only known from a specimen kept in World Museum, Liverpool. Overlooked for much of the 20th century, it was recognised as a valid extinct species by the IUCN Red List only in 2008. In 2014 a genetic study confirmed it as a distinct species related to the Nicobar pigeon, and showed that the two were the closest relatives of the extinct dodo and Rodrigues solitaire.
 Link Information: The animal order Columbiformes is also constituted of pigeons and doves, and includes about 42 genera and 310 species.
 Question: How many species of pigeons are there?
Answer: 310

Passage: Seeing her greatest level of success in the 1980s, Branigan's other singles included the Top 10 hit "Solitaire" (1983), the U.S. AC chart number one "How Am I Supposed to Live Without You" (1983), the Australian No. 2 hit "Ti amo" (1984), and "The Power of Love" (1987). Her most successful album was 1984's platinum-selling Self Control. She also contributed songs to motion picture and television soundtracks, including the Grammy and Academy Award-winning Flashdance soundtrack (1983), and the Ghostbusters soundtrack (1984). In 1985, she won the Tokyo Music Festival with the song "The Lucky One". Her chart success began to wane as the decade closed and after her last two albums Laura Branigan (1990) and Over My Heart (1993) garnered little attention, she generally retired from public life for the rest of the 1990s. She began returning to performing in the early 2000s, most notably appearing as Janis Joplin in the off-Broadway musical Love, Janis. As she was recording new music and preparing a comeback to the music industry, she died at her home in 2004 from a previously undiagnosed cerebral aneurysm. 
 Link Information:  Its worldwide box-office gross exceeded $200 million. Question: Which movie that Branigan was associated with grossed more at the box office?

Passage: In 1983 elections, N. T. Rama Rao came to power defeating the Indian National Congress. He praised the Naxalites for their patriotism before the elections. After coming to power, he demonstrated no significant change in government policy towards the revolutionary movement. Particularly after he was elected for a second time in 1985, his government put all its efforts to suppress the Naxalite movement in the state. Varavara Rao too was subjected to severe repression during this time. Six cases were foisted against him in 1985 alone. In July that year, along with functionaries of other people's organisations, he undertook an all India tour to make the people aware of the repression that was going on in Andhra Pradesh. After visiting Maharashtra, Madhya Pradesh, Bihar, West Bengal, New Delhi and Tamil Nadu, Varavara Rao returned to Andhra Pradesh in September to attend court cases. Dr. Ramanatham, a pediatrician and civil liberties activist was a close friend of Varavara Rao. While killing Dr. Ramanatham, and on several other occasions, police openly declared that killing Varavara Rao was their aim. With his life at risk, Varavara Rao could not discharge his duties as Secretary of Virasam and spokesperson of revolutionary literary movement. He was not able to move freely in Andhra Pradesh. Warangal has become a forbidden place for him. Armed and unarmed ruffians and police in civil clothes attacked his house on several occasions. Persecution against his friends in the movement was also mounted. Taking into consideration all these developments, Varavara Rao chose to cancel his bail in Secunderabad Conspiracy Case. On his request, his bail was cancelled and he was sent to jail on 26 December 1985.
