Problem: Spanish language in the United States:

Calvin Veltman undertook, for the National Center for Education Statistics and for the Hispanic Policy Development Project, the most complete study of English language adoption by Hispanophone immigrants. Mr Veltman's language shift studies document high bilingualism rates and subsequent adoption of English as the preferred language of Hispanics, particularly by the young and the native-born. The complete set of these studies' demographic projections postulates the near-complete assimilation of a given Hispanophone immigrant cohort within two generations. Although his study based itself upon a large 1976 sample from the Bureau of the Census (which has not been repeated), data from the 1990 Census tend to confirm the great Anglicization of the US Hispanic American origin population.

Who undertook the most complete study of Hispanic language adoption?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The crusades were intended to seize Jerusalem from Muslim control. The First Crusade was proclaimed by Pope Urban II (pope 108899) at the Council of Clermont in 1095 in response to a request from the Byzantine Emperor Alexios I Komnenos (r. 10811118) for aid against further Muslim advances. Urban promised indulgence to anyone who took part. Tens of thousands of people from all levels of society mobilised across Europe and captured Jerusalem in 1099. One feature of the crusades was the pogroms against local Jews that often took place as the crusaders left their countries for the East. These were especially brutal during the First Crusade, when the Jewish communities in Cologne, Mainz, and Worms were destroyed, and other communities in cities between the rivers Seine and Rhine suffered destruction. Another outgrowth of the crusades was the foundation of a new type of monastic order, the military orders of the Templars and Hospitallers, which fused monastic life with military service.
What Byzantine Emperor's request for assistance led to the First Crusade?
A: Alexios I Komnenos

Context and question: Tourism has been a key factor in economic development for many Southeast Asian countries, especially Cambodia. According to UNESCO, "tourism, if correctly conceived, can be a tremendous development tool and an effective means of preserving the cultural diversity of our planet." Since the early 1990s, "even the non-ASEAN nations such as Cambodia, Laos, Vietnam and Burma, where the income derived from tourism is low, are attempting to expand their own tourism industries." In 1995, Singapore was the regional leader in tourism receipts relative to GDP at over 8%. By 1998, those receipts had dropped to less than 6% of GDP while Thailand and Lao PDR increased receipts to over 7%. Since 2000, Cambodia has surpassed all other ASEAN countries and generated almost 15% of its GDP from tourism in 2006.
What industry is strong in Cambodia?
Answer: unanswerable

Problem: Arsenal F.C.:

Highbury could hold more than 60,000 spectators at its peak, and had a capacity of 57,000 until the early 1990s. The Taylor Report and Premier League regulations obliged Arsenal to convert Highbury to an all-seater stadium in time for the 199394 season, thus reducing the capacity to 38,419 seated spectators. This capacity had to be reduced further during Champions League matches to accommodate additional advertising boards, so much so that for two seasons, from 1998 to 2000, Arsenal played Champions League home matches at Wembley, which could house more than 70,000 spectators.

During what time did Arsenal play at Wembley?
---
A:
1998 to 2000
