PROBLEM: Passage: She made her first film in 1924, and with her blonde hair, green eyes, delicate features, and good-natured demeanor, was cast in a string of supporting roles, where she was required to do very little but smile and look pretty. She proved herself capable of handling the small roles she was assigned, and over a period of time, she came to be taken seriously as an actress. By 1928, she was playing starring roles, achieving success in MGM's first talkie release, Alias Jimmy Valentine (1928) opposite William Haines, Lionel Barrymore, and Karl Dane. The following year, she appeared in the popular murder mystery The Thirteenth Chair, a role that offered her the chance to display her dramatic abilities as a murder suspect. At Fox that same year, she appeared in director Allan Dwan's now lost romantic adventure The Far Call opposite Charles Morton. The quality of her parts continued to improve as the decade turned, including a role as Robert Montgomery's sister in the prison drama The Big House (1930) with Chester Morris and Wallace Beery, for which Hyams once again received positive reviews. She then appeared in Surrender (1931) in which Warner Baxter and Ralph Bellamy desperately competed for her attention.

PROBLEM: Passage: Nicolò's son Piergiampaolo inherited Sora and Alvito, while another son, Piergiovanni, inherited Popoli. Piergiampaolo soon annexed his brother's Abruzzese lands and, after siding against the new king, Ferdinand I, in the revolt of 1460, captured the territories of Montecassino, Arce, and the fiefs of the Colonna in Abruzzo. He also took part in the sieges of Sulmona and L'Aquila, but was in turn besieged and defeated by Napoleone Orsini at Sora. As a result, he was forced to cede Sora, Arpino, Casalvieri, Isola del Liri, and Fontana Liri to the Papal States in 1463. His duchy was downgraded to a county, the title being assigned to Piergiovanni. At the same time, Alvito and Sora were given the right to mint cavalli (a type of coin). Piergiampaolo organized a second plot against Ferdinand, but was again defeated and had to abandon hopes in returning to Alvito. Exiled to France, he returned with the invading army of Charles VIII of France during the War of 1494–95. With his brother, Sigismondo II of Sora, he re-conquered most of his lands. He was able to resist the Neapolitans after the French retreat, but in 1496 Sora fell to Frederick I of Naples, followed in 1496 by Alvito, captured by general Gonzalo de Córdoba. This put an end to the Cantelmo rule.
