Problem: Comprehensive school:

Gesamtschulen might put bright working class students at risk according to several studies. It could be shown that an achievement gap opens between working class students attending a comprehensive and their middle class peers. Also working class students attending a Gymnasium or a Realschule outperform students from similar backgrounds attending a comprehensive. However it is not students attending a comprehensive, but students attending a Hauptschule, who perform the poorest.

Who could be made vulnerable by the Gasemtschulen?
---
A: bright working class students

Context and question: The Amoy dialect (Xiamen) is a hybrid of the Quanzhou and Zhangzhou dialects. Taiwanese is also a hybrid of these two dialects. Taiwanese in northern Taiwan tends to be based on the Quanzhou variety, whereas the Taiwanese spoken in southern Taiwan tends to be based on Zhangzhou speech. There are minor variations in pronunciation and vocabulary between Quanzhou and Zhangzhou dialects. The grammar is generally the same. Additionally, extensive contact with the Japanese language has left a legacy of Japanese loanwords in Taiwanese Hokkien. On the other hand, the variants spoken in Singapore and Malaysia have a substantial number of loanwords from Malay and to a lesser extent, from English and other Chinese varieties, such as the closely related Teochew and some Cantonese.
Contact with China has lead to loanwords in what dialect?
Answer: unanswerable


Question: Asphalt/bitumen also occurs in unconsolidated sandstones known as "oil sands" in Alberta, Canada, and the similar "tar sands" in Utah, US. The Canadian province of Alberta has most of the world's reserves of natural bitumen, in three huge deposits covering 142,000 square kilometres (55,000 sq mi), an area larger than England or New York state. These bituminous sands contain 166 billion barrels (26.4×10^9 m3) of commercially established oil reserves, giving Canada the third largest oil reserves in the world. and produce over 2.3 million barrels per day (370×10^3 m3/d) of heavy crude oil and synthetic crude oil. Although historically it was used without refining to pave roads, nearly all of the bitumen is now used as raw material for oil refineries in Canada and the United States.
Is there an answer to this question: What is the area amount of the Canadian asphalt deposits?

Answer: 142,000 square kilometres
