Text: For the 1995 season the newly-formed Auckland Warriors became the first club from outside Australia to be admitted to the Australian Rugby League's premiership when it expanded from 16 to 20 teams. As a result of the Super League war in the mid-1990s, Auckland left the ARL to compete in the Super League competition of 1997, before joining the re-unified NRL the following year. They re-branded themselves the New Zealand Warriors in 2001. The club has yet to win a premiership as of 2018, but has won one minor premiership (in 2002), reached two grand finals (2002 and 2011), reached the play-offs eight times, and provided the majority of the New Zealand national team's players.

Question: have the new zealand warriors won a premiership?

Text: During the last years of the Wanli era and those of his two successors, an economic crisis developed that was centered on a sudden widespread lack of the empire's chief medium of exchange: silver. The Portuguese first established trade with China in 1516, trading Japanese silver for Chinese silk, and after some initial hostilities gained consent from the Ming court in 1557 to settle Macau as their permanent trade base in China. Their role in providing silver was gradually surpassed by the Spanish, while even the Dutch challenged them for control of this trade. Philip IV of Spain (reigned 1621--1665) began cracking down on illegal smuggling of silver from New Spain and Peru across the Pacific through the Philippines towards China, in favor of shipping American-mined silver through Spanish ports. In 1639 the new Tokugawa regime of Japan shut down most of its foreign trade with European powers, cutting off another source of silver coming into China. These events occurring at roughly the same time caused a dramatic spike in the value of silver and made paying taxes nearly impossible for most provinces. People began hoarding precious silver as there was progressively less of it, forcing the ratio of the value of copper to silver into a steep decline. In the 1630s a string of one thousand copper coins equaled an ounce of silver; by 1640 that sum could fetch half an ounce; and, by 1643 only one-third of an ounce. For peasants this meant economic disaster, since they paid taxes in silver while conducting local trade and crop sales in copper.

Question: did the influx of silver into china change the lives of peasants?

Text: Crane fly is a common name referring to any member of the insect family Tipulidae, of the order Diptera, true flies in the superfamily Tipuloidea. Cylindrotominae, Limoniinae, and Pediciinae have been ranked as subfamilies of Tipulidae by most authors, though occasionally elevated to family rank. In the most recent classifications, only Pediciidae is now ranked as a separate family, due to considerations of paraphyly. In colloquial speech, crane flies are sometimes known as mosquito hawks or daddy longlegs, a term also used to describe opiliones or the family Pholcidae, both of which are arachnids. The larvae of crane flies are known commonly as leatherjackets.
