High speed Internet connectivity has become more widely available at a reasonable cost and the cost of video capture and display technology has decreased. Consequently, personal videoconferencing systems based on a webcam, personal computer system, software compression and broadband Internet connectivity have become affordable to the general public. Also, the hardware used for this technology has continued to improve in quality, and prices have dropped dramatically. The availability of freeware (often as part of chat programs) has made software based videoconferencing accessible to many.
What has made videoconferencing accessible to many?
A: The availability of freeware

When the war began, the French government ordered a blockade of the North German coasts, which the small North German navy (Norddeutsche Bundesmarine) with only five ironclads could do little to oppose. For most of the war, the three largest German ironclads were out of service with engine troubles; only the turret ship SMS Arminius was available to conduct operations. By the time engine repairs had been completed, the French fleet had already departed. The blockade proved only partially successful due to crucial oversights by the planners in Paris. Reservists that were supposed to be at the ready in case of war, were working in the Newfoundland fisheries or in Scotland. Only part of the 470-ship French Navy put to sea on 24 July. Before long, the French navy ran short of coal, needing 200 short tons (180 t) per day and having a bunker capacity in the fleet of only 250 short tons (230 t). A blockade of Wilhelmshaven failed and conflicting orders about operations in the Baltic Sea or a return to France, made the French naval efforts futile. Spotting a blockade-runner became unwelcome because of the question du charbon; pursuit of Prussian ships quickly depleted the coal reserves of the French ships.
A blockade of what coastline was ordered by the French government at the start of the war?
A: North German coasts

The law of the Eastern Catholic Churches in full union with Rome was in much the same state as that of the Latin or Western Church before 1917; much more diversity in legislation existed in the various Eastern Catholic Churches. Each had its own special law, in which custom still played an important part. In 1929 Pius XI informed the Eastern Churches of his intention to work out a Code for the whole of the Eastern Church. The publication of these Codes for the Eastern Churches regarding the law of persons was made between 1949 through 1958 but finalized nearly 30 years later.
What was finalized in 1958?
A: unanswerable

Phonology is a branch of linguistics concerned with the systematic organization of sounds in languages. It has traditionally focused largely on the study of the systems of phonemes in particular languages (and therefore used to be also called phonemics, or phonematics), but it may also cover any linguistic analysis either at a level beneath the word (including syllable, onset and rime, articulatory gestures, articulatory features, mora, etc.) or at all levels of language where sound is considered to be structured for conveying linguistic meaning. Phonology also includes the study of equivalent organizational systems in sign languages.
