Input: Article: 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.

Now answer this question: What is Calvin Veltman' study about?

Output: the most complete study of English language adoption by Hispanophone immigrants

Article: In the early 1970s the Rolling Stones developed their hard rock sound with Exile on Main St. (1972). Initially receiving mixed reviews, according to critic Steve Erlewine it is now "generally regarded as the Rolling Stones' finest album". They continued to pursue the riff-heavy sound on albums including It's Only Rock 'n' Roll (1974) and Black and Blue (1976). Led Zeppelin began to mix elements of world and folk music into their hard rock from Led Zeppelin III (1970) and Led Zeppelin IV (1971). The latter included the track "Stairway to Heaven", which would become the most played song in the history of album-oriented radio. Deep Purple continued to define hard rock, particularly with their album Machine Head (1972), which included the tracks "Highway Star" and "Smoke on the Water". In 1975 guitarist Ritchie Blackmore left, going on to form Rainbow and after the break-up of the band the next year, vocalist David Coverdale formed Whitesnake. 1970 saw The Who release Live at Leeds, often seen as the archetypal hard rock live album, and the following year they released their highly acclaimed album Who's Next, which mixed heavy rock with extensive use of synthesizers. Subsequent albums, including Quadrophenia (1973), built on this sound before Who Are You (1978), their last album before the death of pioneering rock drummer Keith Moon later that year.

Question: What two hard rock songs are featured on Deep Purple's Machine Head album?
Ans: "Highway Star" and "Smoke on the Water"

Here is a question about this article: The SCN projects to a set of areas in the hypothalamus, brainstem, and midbrain that are involved in implementing sleep-wake cycles. An important component of the system is the reticular formation, a group of neuron-clusters scattered diffusely through the core of the lower brain. Reticular neurons send signals to the thalamus, which in turn sends activity-level-controlling signals to every part of the cortex. Damage to the reticular formation can produce a permanent state of coma.
What is the answer to this question: Damage to the reticular formation can cause what?
****
So... state of coma

Czech typographical features not associated with phonetics generally resemble those of most Latin European languages, including English. Proper nouns, honorifics, and the first letters of quotations are capitalized, and punctuation is typical of other Latin European languages. Writing of ordinal numerals is similar to most European languages. The Czech language uses a decimal comma instead of a decimal point. When writing a long number, spaces between every three numbers (e.g. between hundreds and thousands) may be used for better orientation in handwritten texts, but not in decimal places, like in English. The number 1,234,567.8910 may be written as 1234567,8910 or 1 234 567,8910. Ordinal numbers (1st) use a point as in German (1.). In proper noun phrases (except personal names), only the first word is capitalized (Prazsky hrad, Prague Castle).
In Czech, what is done to proper nouns, honorifics, and the first letters of quotations?
****
The answer: capitalized

The problem: Answer a question about this article:
At the Battle of Pulo Aura, which was probably the company's most notable naval victory, Nathaniel Dance, Commodore of a convoy of Indiamen and sailing aboard the Warley, led several Indiamen in a skirmish with a French squadron, driving them off. Some six years earlier, on 28 January 1797, five Indiamen, the Woodford, under Captain Charles Lennox, the Taunton-Castle, Captain Edward Studd, Canton, Captain Abel Vyvyan, and Boddam, Captain George Palmer, and Ocean, Captain John Christian Lochner, had encountered Admiral de Sercey and his squadron of frigates. On this occasion the Indiamen also succeeded in bluffing their way to safety, and without any shots even being fired. Lastly, on 15 June 1795, the General Goddard played a large role in the capture of seven Dutch East Indiamen off St Helena.
Where were the 7 Dutch Easteast indiamen capture?
****
The answer:
off St Helena
