Input: Read this: In the example above, the identity and the rotations constitute a subgroup R = {id, r1, r2, r3}, highlighted in red in the group table above: any two rotations composed are still a rotation, and a rotation can be undone by (i.e. is inverse to) the complementary rotations 270 for 90, 180 for 180, and 90 for 270 (note that rotation in the opposite direction is not defined). The subgroup test is a necessary and sufficient condition for a subset H of a group G to be a subgroup: it is sufficient to check that g1h H for all elements g, h H. Knowing the subgroups is important in understanding the group as a whole.d["]
Question: What is defined when moving in the opposite direction?

Output: unanswerable

QUES: The Bronx contains one of the five poorest Congressional Districts in the United States, the 15th, but its wide diversity also includes affluent, upper-income and middle-income neighborhoods such as Riverdale, Fieldston, Spuyten Duyvil, Schuylerville, Pelham Bay, Pelham Gardens, Morris Park and Country Club. The Bronx, particularly the South Bronx, saw a sharp decline in population, livable housing, and the quality of life in the late 1960s and the 1970s, culminating in a wave of arson. Since then the communities have shown significant redevelopment starting in the late 1980s before picking up pace in the 1990s into today.

What neighborhoods of the Bronx are more affluent?
What is the answer?
ANS: Riverdale, Fieldston, Spuyten Duyvil, Schuylerville, Pelham Bay, Pelham Gardens, Morris Park and Country Club

QUES: The United States shares land borders with Canada (to the north) and Mexico (to the south), and a territorial water border with Russia in the northwest, and two territorial water borders in the southeast between Florida and Cuba, and Florida and the Bahamas.

Alaska borders the Pacific Ocean to the south, the Bering Strait to the west, and the Arctic Ocean to the north, while Hawaii lies far to the southwest of the mainland in the Pacific Ocean.
Which ocean does Alaska border to the south?

In 1579 the northern seven provinces signed the Union of Utrecht, in which they decided to join forces against Spanish rule. The Union of Utrecht is seen as the beginning of the Dutch Republic. In 1580 the new and predominantly Protestant state abolished the bishoprics, including the archbishopric of Utrecht. The stadtholders disapproved of the independent course of the Utrecht bourgeoisie and brought the city under much more direct control of the republic; which shifted the power towards its dominant province Holland. This was the start of a long period of stagnation of trade and development in Utrecht. Utrecht remained an atypical city in the new republic with about 40% Catholic in the mid-17th century, and even more among the elite groups, who included many rural nobility and gentry with town houses there.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What became the dominant province
Ah, so.. towards its dominant province Holland

Input: Read this: On 16 March 2012, 52 Greenpeace activists from five different countries boarded Fennica and Nordica, multipurpose icebreakers chartered to support Shell's drilling rigs near Alaska. Around the same time period, a reporter for Fortune magazine spoke with Edward Itta, an Inupiat Eskimo leader and the former mayor of the North Slope Borough, who expressed that he was conflicted about Shell's plans in the Arctic, as he was very concerned that an oil spill could destroy the Inupiat Eskimo's hunting-and-fishing culture, but his borough also received major tax revenue from oil and gas production; additionally, further revenue from energy activity was considered crucial to the future of the living standard in Itta's community.
Question: How many Greenpeace activists boarded Fennica and Nordica in March 2012?
