Input: Consider Input: Passage: From the founding of modern Singapore in 1819 until 1826, Singapore was headed by two residents in succession. Following Singapore's amalgamation into the Straits Settlements in 1826, it was governed by a governor together with a legislative council. An executive council of the Straits Settlements was introduced in 1877 to advise the Governor but wielded no executive power. In 1955, a Council of Ministers was created, appointed by the Governor on the recommendation of the Leader of the House. Constitutional talks between Legislative Assembly representatives and the Colonial Office were held from 1956 to 1958, and Singapore gained full internal self-government in 1959. The governor was replaced by the Yang di-Pertuan Negara, who had power to appoint to the post of prime minister the person most likely to command the authority of the assembly, and other ministers of the Cabinet on the prime minister's advice. In the 1959 general elections, the People's Action Party (PAP) swept to power with 43 out of the 51 seats in the assembly, and Lee Kuan Yew became the first prime minister of Singapore. The executive branch of the Singapore Government remained unchanged following Singapore's merger with Malaysia in 1963, and subsequent independence in 1965. The PAP has been returned to power in every general election and has thus formed the Cabinet since 1959. The government is generally perceived to be competent in managing the country's economy and largely free from political corruption. On the other hand, it has been criticized for using unfair election tactics, violating freedom of speech and its excessive use of the death penalty (by hanging) for non-violent crimes.

Input: Consider Input: Passage: Pinza sang once again under the baton of Toscanini in 1935, this time with the New York Philharmonic Orchestra, as the bass soloist in performances of Beethoven's Missa Solemnis. One of these performances was broadcast by CBS and preserved on transcription discs; this recording has been issued on LPs and CDs. He also sang in Toscanini's February 6, 1938, NBC Symphony Orchestra's broadcast performance of Beethoven's Ninth Symphony. These performances both took place in Carnegie Hall. In March 1942, Pinza was arrested at his home and unjustly detained 3 months on Ellis Island with hundreds of other Italian-Americans who were suspected of supporting the Axis. The incident was extremely traumatic for Pinza, and he suffered from severe depression for years afterward. In October 1947, he performed the role of Méphistophélès in Guonod's Faust opposite his daughter, soprano Claudia Pinza Bozzolla, as Marguerite at the San Francisco Opera.

Input: Consider Input: Passage: The church is constructed in punch-dressed sandstone ashlar, and has slate roofs with inserted skylight windows. Its architectural style is Early English. The plan consists of a four-bay nave without aisles, a two-bay chancel with a north chapel and a south vestry, and a west tower. The tower is in three stages, with clasping buttresses, and contains paired west doorways, a clock face in a diamond-shaped surround, and pairs of louvred bell openings. At the top of the tower is an embattled parapet with octagonal corner pinnacles, and there are more pinnacles at the angles of the nave. The bays of the nave are separated by buttresses, and each bay contains a corbel-table and a pair of lancet windows. The sides of the chancel also contain paired lancet windows, and the east window consists of a triple stepped lancet in a blank arch. The north chapel is gabled, and contains a wheel window. The interior has been remodelled, but originally it contained a three-sided gallery on cast iron columns.
