QUES: Before the 1950s, the department store held an eminent place in both Canada and Australia, during both the Great Depression and World War II. Since then, they have suffered from strong competition from specialist stores. Most recently the competition has intensified with the advent of larger-scale superstores (Jones et al. 1994; Merrilees and Miller 1997). Competition was not the only reason for the department stores' weakening strength; the changing structure of cities also affected them. The compact and centralized 19th century city with its mass transit lines converging on the downtown was a perfect environment for department store growth. But as residents moved out of the downtown areas to the suburbs, the large, downtown department stores became inconvenient and lost business to the newer suburban shopping malls. In 2003, U.S. department store sales were surpassed by big-box store sales for the first time (though some stores may be classified as "big box" by physical layout and "department store" by merchandise).
What factor lead to a increase in department store shoppers?

ANS: unanswerable

Anti-miscegenation laws were passed in most states during the 18th, 19th and early 20th centuries, but this did not prevent white slaveholders, their sons, or other powerful white men from taking slave women as concubines and having multiracial children with them. In California and the western US, there were greater numbers of Latino and Asian residents. These were prohibited from official relationships with whites. White legislators passed laws prohibiting marriage between European and Asian Americans until the 1950s.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When were the laws against marriage between Asians and Europeans lifted?
Ah, so.. 1950s

Problem: The Norfolk Island Group Nepean Island is also home to breeding seabirds. The providence petrel was hunted to local extinction by the beginning of the 19th century, but has shown signs of returning to breed on Phillip Island. Other seabirds breeding there include the white-necked petrel, Kermadec petrel, wedge-tailed shearwater, Australasian gannet, red-tailed tropicbird and grey ternlet. The sooty tern (known locally as the whale bird) has traditionally been subject to seasonal egg harvesting by Norfolk Islanders.
What other types of petrels are extinct on Phillip Island?
