The problem: Answer a question about this article:
Some systems are capable of multipoint conferencing with no MCU, stand-alone, embedded or otherwise. These use a standards-based H.323 technique known as "decentralized multipoint", where each station in a multipoint call exchanges video and audio directly with the other stations with no central "manager" or other bottleneck. The advantages of this technique are that the video and audio will generally be of higher quality because they don't have to be relayed through a central point. Also, users can make ad-hoc multipoint calls without any concern for the availability or control of an MCU. This added convenience and quality comes at the expense of some increased network bandwidth, because every station must transmit to every other station directly.
What is one disadvantage of using the H.323 technique?
****
The answer: increased network bandwidth

The 15th century was a time of Islamic economic expansion, known as the Valencian Golden Age, in which culture and the arts flourished. Concurrent population growth made Valencia the most populous city in the Crown of Aragon. Local industry, led by textile production, reached a great development, and a financial institution, the Canvi de Taula, was created to support municipal banking operations; Valencian bankers lent funds to Queen Isabella I of Castile for Columbus's voyage in 1492. At the end of the century the Silk Exchange (Llotja de la Seda) building was erected as the city became a commercial emporium that attracted merchants from all over Europe.
What was Valencia's leading industry?
****
The answer: textile production


The problem: Answer a question about this article:
Music was a major part of everyday life.[citation needed] The word itself derives from Greek μουσική (mousike), "(art) of the Muses". Many private and public events were accompanied by music, ranging from nightly dining to military parades and manoeuvres. In a discussion of any ancient music, however, non-specialists and even many musicians have to be reminded that much of what makes our modern music familiar to us is the result of developments only within the last 1,000 years; thus, our ideas of melody, scales, harmony, and even the instruments we use may not have been familiar to Romans who made and listened to music many centuries earlier.[citation needed]
What do many people consider to be the source of our modern musics familiarity with us?
****
The answer:
developments only within the last 1,000 years
