Beginning and ending dates are roughly the reverse in the southern hemisphere. For example, mainland Chile observed DST from the second Saturday in October to the second Saturday in March, with transitions at 24:00 local time. The time difference between the United Kingdom and mainland Chile could therefore be five hours during the Northern summer, three hours during the Southern summer and four hours a few weeks per year because of mismatch of changing dates.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): During what season in the Southern hemisphere is there a three-hour time difference between mainland Chile and the United Kingdom?
Ah, so.. summer

At dawn on Sunday, 25 June 1950, the Korean People's Army crossed the 38th parallel behind artillery fire. The KPA justified its assault with the claim that ROK troops had attacked first, and that they were aiming to arrest and execute the "bandit traitor Syngman Rhee". Fighting began on the strategic Ongjin peninsula in the west. There were initial South Korean claims that they had captured the city of Haeju, and this sequence of events has led some scholars to argue that the South Koreans actually fired first.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who claimed to have taken control of Haeju?
Ah, so.. the South Koreans

Vietnam: The event was held in Ho Chi Minh City on April 29. Some 60 torchbearers carried the torch from the downtown Opera House to the Military Zone 7 Competition Hall stadium near Tan Son Nhat International Airport along an undisclosed route. Vietnam is involved in a territorial dispute with China (and other countries) for sovereignty of the Spratly and Paracel Islands; tensions have risen recently[when?] following reports that the Chinese government had established a county-level city named Sansha in the disputed territories, resulting in anti-Chinese demonstrations in December 2007 in Hanoi and Ho Chi Minh City. However to sustain its relationship with China the Vietnamese government has actively sought to head off protests during the torch relay, with Prime Minister Nguyen Tan Dung warning government agencies that "hostile forces" may try to disrupt the torch relay.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When did the torch arrive in Vietnam?
Ah, so..
