input: Please answer the following: The answer to the question: What two groups' alliance was broken when the Song recaptured the former imperial capitals of Kaifeng? is inside the article: The Mongols were allied with the Song, but this alliance was broken when the Song recaptured the former imperial capitals of Kaifeng, Luoyang, and Chang'an at the collapse of the Jin dynasty. The Mongol leader Mongke Khan led a campaign against the Song in 1259 but died on August 11 during the Siege of Diaoyu Castle in Chongqing. Mongke's death and the ensuing succession crisis prompted Hulagu Khan to pull the bulk of the Mongol forces out of the Middle East where they were poised to fight the Egyptian Mamluks (who defeated the remaining Mongols at Ain Jalut). Although Hulagu was allied with Kublai Khan, his forces were unable to help in the assault against the Song, due to Hulagu's war with the Golden Horde.Kublai continued the assault against the Song, gaining a temporary foothold on the southern banks of the Yangtze. Kublai made preparations to take Ezhou, but a pending civil war with his brother Ariq Bokea rival claimant to the Mongol Khaganateforced Kublai to move back north with the bulk of his forces. In Kublai's absence, the Song forces were ordered by Chancellor Jia Sidao to make an immediate assault and succeeded in pushing the Mongol forces back to the northern banks of the Yangtze. There were minor border skirmishes until 1265, when Kublai won a significant battle in Sichuan.From 1268 to 1273, Kublai blockaded the Yangtze River with his navy and besieged Xiangyang, the last obstacle in his way to invading the rich Yangtze River basin. Kublai officially declared the creation of the Yuan dynasty in 1271. In 1275, a Song force of 130,000 troops under Chancellor Jia Sidao was defeated by Kublai's newly appointed commander-in-chief, general Bayan. By 1276, most of the Song territory had been captured by Yuan forces, including the capital Lin'an.In the Battle of Yamen on the Pearl River Delta in 1279, the Yuan army, led by the general Zhang Hongfan, finally crushed the Song resistance. The last remaining ruler, the 8-year-old emperor Emperor Huaizong of Song, committed suicide, along with Prime..., can you guess it ?

input: Please answer the following: The answer to the question: What piece of evidence found at the impact origin of the crater was a gravity anomaly? is inside the article: The Chicxulub crater (; Mayan: [t'ikulu]) is an impact crater buried underneath the Yucatan Peninsula in Mexico. Its center is located near the town of Chicxulub, after which the crater is named. It was formed by a large asteroid or comet about 11 to 81 kilometres (6.8 to 50.3 miles) in diameter, the Chicxulub impactor, striking the Earth. The date of the impact coincides precisely with the CretaceousPaleogene boundary (KPg boundary), slightly less than 66 million years ago, and a widely accepted theory is that worldwide climate disruption from the event was the cause of the CretaceousPaleogene extinction event, a mass extinction in which 75% of plant and animal species on Earth became extinct, including all non-avian dinosaurs. The crater is estimated to be 150 kilometres (93 miles) in diameter and 20 km (12 mi) in depth, well into the continental crust of the region of about 1030 km (6.218.6 mi) depth. It is the second largest confirmed impact structure on Earth and the only one whose peak ring is intact and directly accessible for scientific research.The crater was discovered by Antonio Camargo and Glen Penfield, geophysicists who had been looking for petroleum in the Yucatan during the late 1970s. Penfield was initially unable to obtain evidence that the geological feature was a crater and gave up his search. Later, through contact with Alan Hildebrand in 1990, Penfield obtained samples that suggested it was an impact feature. Evidence for the impact origin of the crater includes shocked quartz, a gravity anomaly, and tektites in surrounding areas. In 2016, a scientific drilling project drilled deep into the peak ring of the impact crater, hundreds of meters below the current sea floor, to obtain rock core samples from the impact itself. The discoveries were widely seen as confirming current theories related to both the crater impact and its effects., can you guess it ?

input: Please answer the following: The answer to the question: Who Theodore Drew pretend to be in order to scare off the hotel manicurist's date? is inside the article: Brought up in poverty, hotel manicurist Regi Allen wants to marry a rich husband. Her new client, wheelchair-using hotel guest Allen Macklyn is immediately attracted to her and becomes her confidant. Despite his obvious wealth, Regi does not view him as a potential husband, and has no qualms about telling him about her goal in life. Exiting his penthouse suite, she encounters a man playing hop-scotch in the hallway, and declines his invitation to join him. He makes an appointment for a manicure as Theodore Drew III, scion of a socially prominent family. Unaware that the Drews were bankrupted by the Great Depression, she accepts his invitation to dinner. They have a good time, but Ted drinks too much and tells Regi that he is engaged to Vivian Snowden, heiress to a pineapple fortune. When Regi is unable to wake him from his drunken slumber, she lets him sleep on her sofa. He explains to her that he was supposed to sail to Bermuda last night (a trip paid for by his future father-in-law) and that he has nowhere to stay and no money. Regi reluctantly lets him live in her apartment until his boat returns from Bermuda, at which time he can return to sponging off of Vivian. Ted and Regi confess to each other that they intend to marry for money. Ted and Regi play fun pranks on each other. In the first one, Ted frightens away Regi's date by pretending to be her abusive husband. Later, in order to convince Vivian that he is in Bermuda, Ted persuades Regi to telephone Vivian while posing as a Bermuda telephone operator. When Regi repeatedly interrupts in a nasally voice, Ted hangs up to avoid laughing in his fiancee's hearing. However, this backfires, as Vivian discovers that the call came from New York when she tries to reconnect. She hires private investigators to find out what is going on., can you guess it ?
