Problem: Francis Albert Sinatra was born on December 12, 1915, in an upstairs tenement at 415 Monroe Street in Hoboken, New Jersey. He was the only child of Italian immigrants Antonino Martino "Marty" Sinatra and Natalina "Dolly" Garaventa. Sinatra weighed 13.5 pounds (6.1 kg) at birth and had to be delivered with the aid of forceps, which caused severe scarring to his left cheek, neck, and ear, and perforated his ear drum, damage that remained for life. Due to his injuries at birth, his baptism at St. Francis Church in Hoboken was delayed until April 2, 1916.

Sinatra attempted to pursue an acting career in Hollywood in the early 1940s. While films appealed to him, being exceptionally self-confident, he was rarely enthusiastic towards his own acting, once remarking that "pictures stink". Sinatra made his film debut in 1941, performing in an uncredited sequence in Las Vegas Nights, singing "I'll Never Smile Again" with Tommy Dorsey's The Pied Pipers. In 1943 he had a cameo role along with Duke Ellington and Count Basie in Charles Barton's Reveille with Beverly, making a brief appearance singing "Night and Day". The following year he was given his leading roles in Higher and Higher and Step Lively for RKO Pictures. In 1945, Metro-Goldwyn-Mayer cast Sinatra opposite Gene Kelly and Kathryn Grayson in the Technicolor musical Anchors Aweigh, in which he played a sailor on leave in Hollywood for four days. A major success, it garnered several Academy Award wins and nominations, and the song "I Fall in Love Too Easily", sung by Sinatra in the film, was nominated for the Academy Award for Best Original Song. In 1946, Sinatra briefly appeared at the end of Richard Whorf's commercially successful Till the Clouds Roll By, a Technicolor musical biopic of Jerome Kern, in which he sang "Ol' Man River. In 1949, Sinatra co-starred with Gene Kelly in the Technicolor musical Take Me Out to the Ball Game, a film set in 1908, in which Sinatra and Kelly play baseball players who are part-time vaudevillians. He teamed up with Kelly for a third time in On the Town, playing a sailor on leave in New York City. Today the film is rated very highly by critics, and in 2006 it ranked No. 19 on the American Film Institute's list of best musicals. Both Double Dynamite (1951), an RKO Irving Cummings comedy produced by Howard Hughes, and Joseph Pevney's Meet Danny Wilson (1952) failed to make an impression. The New York World Telegram and Sun ran the headline "Gone on Frankie in '42; Gone in '52".

Question:
The Amorites (; Sumerian MAR.TU; Akkadian Tidnum or Amurrum; Egyptian Amar; Hebrew mvry 'Emori; Ancient Greek: Amorraioi) were an ancient Semitic-speaking people from Syria who also occupied large parts of southern Mesopotamia from the 21st century BC to the end of the 17th century BC, where they established several prominent city states in existing locations, notably Babylon, which was raised from a small town to an independent state and a major city. The term Amurru in Akkadian and Sumerian texts refers to both them and to their principal deity. The Amorites are also mentioned the Bible as inhabitants of Caanan both before and after the conquest of the land under Joshua.
In the earliest Sumerian sources concerning the Amorites, beginning about 2400 BC, the land of the Amorites ("the Mar.tu land") is associated not with Mesopotamia but with the lands to the west of the Euphrates, including Canaan and what was to become Syria by the 3rd century BC, then known as The land of the Amurru, and later as Aram and Eber-Nari. They appear as an uncivilized and nomadic people in early Mesopotamian writings from Sumer, Akkad, and Assyria, especially connected with the mountainous region now called Jebel Bishri in northern Syria called the "mountain of the Amorites". The ethnic terms Mar.tu (Westerners), Amurru (likely derived from 'aburru', pasture) and Amar were used for them in Sumerian, Akkadian, and Ancient Egyptian respectively. From the 21st century BC, possibly triggered by a long major drought starting about 2200 BC, a large-scale migration of Amorite tribes infiltrated southern Mesopotamia. They were one of the instruments of the downfall of the Third Dynasty of Ur, and Amorite dynasties both usurped native rulers of long-extant Babylonian city-states such as Isin, Larsa, Eshnunna, and Kish and also established new ones, the most famous of which was to become Babylon, although it was initially a minor and insignificant state. Known Amorites wrote in a dialect of Akkadian found on tablets at Mari dating from 1800-1750 BC. Since the language shows northwest Semitic forms, words and constructions, the Amorite language is a Northwest Semitic language, and possibly one of the Canaanite languages. The main sources for the extremely limited knowledge about Amorite are the proper names, not Akkadian in style, that are preserved in such texts. The Akkadian language of the native Semitic states, cities and polities of Mesopotamia (Akkad, Assyria, Babylonia, Isin, Kish, Larsa, Ur, Nippur, Uruk, Eridu, Adab, Akshak, Eshnunna, Nuzi, Ekallatum, etc.), was from the east Semitic, as was the Eblaite of the northern Levant.
