Problem: Idealism:

J. M. E. McTaggart of Cambridge University, argued that minds alone exist and only relate to each other through love. Space, time and material objects are unreal. In The Unreality of Time he argued that time is an illusion because it is impossible to produce a coherent account of a sequence of events. The Nature of Existence (1927) contained his arguments that space, time, and matter cannot possibly be real. In his Studies in Hegelian Cosmology (Cambridge, 1901, p196) he declared that metaphysics are not relevant to social and political action. McTaggart "thought that Hegel was wrong in supposing that metaphysics could show that the state is more than a means to the good of the individuals who compose it". For McTaggart "philosophy can give us very little, if any, guidance in action... Why should a Hegelian citizen be surprised that his belief as to the organic nature of the Absolute does not help him in deciding how to vote? Would a Hegelian engineer be reasonable in expecting that his belief that all matter is spirit should help him in planning a bridge?

According to McTaggart, what are the only things that have real existence?

A: minds

Problem: Hong Kong: The event was held in Hong Kong on May 2. In the ceremony held at the Hong Kong Cultural Centre in Tsim Sha Tsui, Chief Executive Donald Tsang handed the torch to the first torchbearer, Olympic medalist Lee Lai Shan. The torch relay then traveled through Nathan Road, Lantau Link, Sha Tin (crossed Shing Mun River via a dragon boat, which had been never used before in the history of Olympic torch relays), Victoria Harbour (crossed by Tin Hau, a VIP vessel managed by the Marine Department) before ending in Golden Bauhinia Square in Wan Chai. A total of 120 torchbearers were selected to participate in the event consisting of celebrities, athletes and pro-Beijing camp politicians. No politicians from the pro-democracy camp were selected as torchbearers. One torchbearer could not participate due to flight delay. It was estimated that more than 200,000 spectators came out and watched the relay. Many enthusiastic supporters wore red shirts and waved large Chinese flags. According to Hong Kong Chief Secretary for Administration Henry Tang, 3,000 police were deployed to ensure order.
When did the torch arrive in Hong Kong?

Context and question: LEDs have also been used as a medium-quality voltage reference in electronic circuits. The forward voltage drop (e.g. about 1.7 V for a normal red LED) can be used instead of a Zener diode in low-voltage regulators. Red LEDs have the flattest I/V curve above the knee. Nitride-based LEDs have a fairly steep I/V curve and are useless for this purpose. Although LED forward voltage is far more current-dependent than a Zener diode, Zener diodes with breakdown voltages below 3 V are not widely available.
LED forward voltage is more current-dependent than what diode?
Answer: Zener

Question: In 1924, the Tajik Autonomous Soviet Socialist Republic was created as a part of Uzbekistan, but in 1929 the Tajik Soviet Socialist Republic (Tajik SSR) was made a separate constituent republic, however the predominantly ethnic Tajik cities of Samarkand and Bukhara remained in the Uzbek SSR. Between 1927 and 1934, collectivization of agriculture and a rapid expansion of cotton production took place, especially in the southern region. Soviet collectivization policy brought violence against peasants and forced resettlement occurred throughout Tajikistan. Consequently, some peasants fought collectivization and revived the Basmachi movement. Some small scale industrial development also occurred during this time along with the expansion of irrigation infrastructure.
Is there an answer to this question: Where was the expansion of cotton and agriculture mainly?

Answer: in the southern region

Problem: Korean War:

By spring 1950, Stalin believed the strategic situation had changed. The Soviets had detonated their first nuclear bomb in September 1949; American soldiers had fully withdrawn from Korea; the Americans had not intervened to stop the communist victory in China, and Stalin calculated that the Americans would be even less willing to fight in Koreawhich had seemingly much less strategic significance. The Soviets had also cracked the codes used by the US to communicate with the US embassy in Moscow, and reading these dispatches convinced Stalin that Korea did not have the importance to the US that would warrant a nuclear confrontation. Stalin began a more aggressive strategy in Asia based on these developments, including promising economic and military aid to China through the SinoSoviet Friendship, Alliance, and Mutual Assistance Treaty.

Where did Stalin engage in an aggressive political strategy?

A:
Asia
