Q: 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.

Q: Passage: Both Sui and Tang empires occupied the same location. In 582, Emperor Wen of the Sui dynasty sited a new region southeast of the much ruined Han Dynasty Chang'an to build his new capital, which he called Daxing (大興, “Great Prosperity”). Daxing was renamed Chang'an in year 618 when the Duke of Tang, Li Yuan, proclaimed himself the Emperor Gaozu of Tang. Chang'an during the Tang dynasty (618–907) was, along with Constantinople (Istanbul) and Baghdad, one of the largest cities in the world. It was a cosmopolitan urban center with considerable foreign populations from other parts of Asia and beyond. This new Chang'an was laid out on a north-south axis in a grid pattern, dividing the enclosure into 108 wards and featuring two large marketplaces, in the east and west respectively. Everyday, administrators of the two marketplaces would beat gong for three hundred times in the morning and evening to signify the start and stop of business. People lived in the wards were not allowed to go outside after curfew. Officials with higher-ranking had the privilege to live closer to the central avenue. Chang'an's layout influenced city planning of several other Asian capitals for many years to come. Chang'an's walled and gated wards were much larger than conventional city blocks seen in modern cities, as the smallest ward had a surface area of 68 acres and the largest ward had a surface area of . The height of the walls enclosing each ward were on average 9 to in height. The Japanese built their ancient capitals, Heijō-kyō (today's Nara) and later Heian-kyō or Kyoto, modelled after Chang'an in a more modest scale yet was never fortified. The modern Kyoto still retains some characteristics of Sui-Tang Chang'an. Similarly, the Korean Silla dynasty modeled their capital of Gyeongju after the Chinese capital. Sanggyeong, one of the five capitals of the state of Balhae, was also laid out like Chang'an.
