Problem: Adolescence:

Teenage alcohol drug use is currently at an all-time low. Out of a polled body of students, 4.4% of 8th graders reported having been on at least one occasion been drunk within the previous month; for 10th graders, the number was 13.7%, and for 12th graders, 25%. More drastically, cigarette smoking has become a far less prevalent activity among American middle- and high-school students; in fact, a greater number of teens now smoke marijuana than smoke cigarettes, with one recent study showing a respective 15.2% versus 11.7% of surveyed students. Recent studies have shown that male late adolescents are far more likely to smoke cigarettes rather than females. The study indicated that there was a discernible gender difference in the prevalence of smoking among the students. The finding of the study show that more males than females began smoking when they were in primary and high schools whereas most females started smoking after high school. This may be attributed to recent changing social and political views towards marijuana; issues such as medicinal use and legalization have tended towards painting the drug in a more positive light than historically, while cigarettes continue to be vilified due to associated health risks.

What is one possible explanation for the shift towards marijuana and away from cigarettes?

A: recent changing social and political views towards marijuana

Problem: The most pelagic species, mainly in the 'tubenose' order Procellariiformes, are great wanderers, and the albatrosses of the southern oceans may circle the globe as they ride the "roaring forties" outside the breeding season. The tubenoses spread widely over large areas of open ocean, but congregate when food becomes available. Many are also among the longest-distance migrants; sooty shearwaters Puffinus griseus nesting on the Falkland Islands migrate 14,000 km (8,700 mi) between the breeding colony and the North Atlantic Ocean off Norway. Some Manx shearwaters Puffinus puffinus do this same journey in reverse. As they are long-lived birds, they may cover enormous distances during their lives; one record-breaking Manx shearwater is calculated to have flown 8 million km (5 million miles) during its over-50 year lifespan.
How long did the Manx shearwater live?

Answer: 50 year

Question: In the mid-19th century, Serbian (led by self-taught writer and folklorist Vuk Stefanovic Karadzic) and most Croatian writers and linguists (represented by the Illyrian movement and led by Ljudevit Gaj and uro Danicic), proposed the use of the most widespread dialect, Shtokavian, as the base for their common standard language. Karadzic standardised the Serbian Cyrillic alphabet, and Gaj and Danicic standardized the Croatian Latin alphabet, on the basis of vernacular speech phonemes and the principle of phonological spelling. In 1850 Serbian and Croatian writers and linguists signed the Vienna Literary Agreement, declaring their intention to create a unified standard. Thus a complex bi-variant language appeared, which the Serbs officially called "Serbo-Croatian" or "Serbian or Croatian" and the Croats "Croato-Serbian", or "Croatian or Serbian". Yet, in practice, the variants of the conceived common literary language served as different literary variants, chiefly differing in lexical inventory and stylistic devices. The common phrase describing this situation was that Serbo-Croatian or "Croatian or Serbian" was a single language. During the Austro-Hungarian occupation of Bosnia and Herzegovina, the language of all three nations was called "Bosnian" until the death of administrator von Kallay in 1907, at which point the name was changed to "Serbo-Croatian".
Is there an answer to this question: Why was Shtokavian suggested as a common language base?

Answer: most widespread dialect

Early digital computers were electromechanical; electric switches drove mechanical relays to perform the calculation. These devices had a low operating speed and were eventually superseded by much faster all-electric computers, originally using vacuum tubes. The Z2, created by German engineer Konrad Zuse in 1939, was one of the earliest examples of an electromechanical relay computer.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Konrad Zuse was an engineer with what nationality?
Ah, so..
German
