Here is a question about this article: Around the 6th century, Slavs appeared on Byzantine borders in great numbers.[page needed] The Byzantine records note that grass would not regrow in places where the Slavs had marched through, so great were their numbers. After a military movement even the Peloponnese and Asia Minor were reported to have Slavic settlements. This southern movement has traditionally been seen as an invasive expansion. By the end of the 6th century, Slavs had settled the Eastern Alps regions.
What is the answer to this question: When had the Slavs settled the Eastern Alps?
****
So... By the end of the 6th century


Here is a question about this article: In response to a given problem situation (), a number of competing conjectures, or tentative theories (), are systematically subjected to the most rigorous attempts at falsification possible. This process, error elimination (), performs a similar function for science that natural selection performs for biological evolution. Theories that better survive the process of refutation are not more true, but rather, more "fit"—in other words, more applicable to the problem situation at hand (). Consequently, just as a species' biological fitness does not ensure continued survival, neither does rigorous testing protect a scientific theory from refutation in the future. Yet, as it appears that the engine of biological evolution has, over many generations, produced adaptive traits equipped to deal with more and more complex problems of survival, likewise, the evolution of theories through the scientific method may, in Popper's view, reflect a certain type of progress: toward more and more interesting problems (). For Popper, it is in the interplay between the tentative theories (conjectures) and error elimination (refutation) that scientific knowledge advances toward greater and greater problems; in a process very much akin to the interplay between genetic variation and natural selection.
What is the answer to this question: What is another term for the tentative theories enter the process of error elimination in science? 
****
So... conjectures


Here is a question about this article: Over 90 weeklies, fortnightlies and quarterlies are published in Sanskrit. Sudharma, a daily newspaper in Sanskrit, has been published out of Mysore, India, since 1970, while Sanskrit Vartman Patram and Vishwasya Vrittantam started in Gujarat during the last five years. Since 1974, there has been a short daily news broadcast on state-run All India Radio. These broadcasts are also made available on the internet on AIR's website. Sanskrit news is broadcast on TV and on the internet through the DD National channel at 6:55 AM IST.
What is the answer to this question: Approximately how many weeklies, fortnightlies and quarterlies published in Sanskrit?
