Input: Article: West European scientists judge the Yugoslav language policy as an exemplary one: although three-quarters of the population spoke one language, no single language was official on a federal level. Official languages were declared only at the level of constituent republics and provinces, and very generously: Vojvodina had five (among them Slovak and Romanian, spoken by 0.5 per cent of the population), and Kosovo four (Albanian, Turkish, Romany and Serbo-Croatian). Newspapers, radio and television studios used sixteen languages, fourteen were used as languages of tuition in schools, and nine at universities. Only the Yugoslav Army used Serbo-Croatian as the sole language of command, with all other languages represented in the army’s other activities—however, this is not different from other armies of multilingual states, or in other specific institutions, such as international air traffic control where English is used worldwide. All variants of Serbo-Croatian were used in state administration and republican and federal institutions. Both Serbian and Croatian variants were represented in respectively different grammar books, dictionaries, school textbooks and in books known as pravopis (which detail spelling rules). Serbo-Croatian was a kind of soft standardisation. However, legal equality could not dampen the prestige Serbo-Croatian had: since it was the language of three quarters of the population, it functioned as an unofficial lingua franca. And within Serbo-Croatian, the Serbian variant, with twice as many speakers as the Croatian, enjoyed greater prestige, reinforced by the fact that Slovene and Macedonian speakers preferred it to the Croatian variant because their languages are also Ekavian. This is a common situation in other pluricentric languages, e.g. the variants of German differ according to their prestige, the variants of Portuguese too. Moreover, all languages differ in terms of prestige: "the fact is that languages (in terms of prestige, learnability etc.) are not equal, and the law cannot make them equal".

Now answer this question: Of the two Serbo-Croatian variants, which had twice as many speakers as the other?

Output: Serbian


Article: An alternative concept is that they formed closer to the Sun, where the matter density was higher, and then subsequently migrated to their current orbits after the removal of the gaseous protoplanetary disc. This hypothesis of migration after formation is favoured, due to its ability to better explain the occupancy of the populations of small objects observed in the trans-Neptunian region. The current most widely accepted explanation of the details of this hypothesis is known as the Nice model, which explores the effect of a migrating Neptune and the other giant planets on the structure of the Kuiper belt.

Question: What does The Nice model consider effected the migration of Neptune?
Ans: Kuiper belt.


Here is a question about this article: The storage in sensory memory and short-term memory generally has a strictly limited capacity and duration, which means that information is not retained indefinitely. By contrast, long-term memory can store much larger quantities of information for potentially unlimited duration (sometimes a whole life span). Its capacity is immeasurable. For example, given a random seven-digit number we may remember it for only a few seconds before forgetting, suggesting it was stored in our short-term memory. On the other hand, we can remember telephone numbers for many years through repetition; this information is said to be stored in long-term memory.
What is the answer to this question: If a memory that is stored in with long term-memories, how long can you possibly rememeber it?
****
So... sometimes a whole life span)

The foundation trust invests undistributed assets, with the exclusive goal of maximizing the return on investment.
