Here is a question about this article: Many smaller clans mentioned within early literature seem to have been present across the rest of the subcontinent. Some of these kings were hereditary; other states elected their rulers. Early "republics" such as the Vajji (or Vriji) confederation centered in the city of Vaishali, existed as early as the 6th century BCE and persisted in some areas until the 4th century CE. The educated speech at that time was Sanskrit, while the languages of the general population of northern India are referred to as Prakrits. Many of the sixteen kingdoms had coalesced to four major ones by 500/400 BCE, by the time of Gautama Buddha. These four were Vatsa, Avanti, Kosala, and Magadha. The Life of Gautam Budhha was mainly associated with these four kingdoms.
What is the answer to this question: Where was the Vajji confederation located?
****
So... Vaishali

Here is a question about this article: The mid-1970s saw the introduction of dbx-encoded records, again for the audiophile niche market. These were completely incompatible with standard record playback preamplifiers, relying on the dbx compandor encoding/decoding scheme to greatly increase dynamic range (dbx encoded disks were recorded with the dynamic range compressed by a factor of two in dB: quiet sounds were meant to be played back at low gain and loud sounds were meant to be played back at high gain, via automatic gain control in the playback equipment; this reduced the effect of surface noise on quiet passages). A similar and very short-lived scheme involved using the CBS-developed "CX" noise reduction encoding/decoding scheme.
What is the answer to this question: What was required for quality playback of DBX recordings?
****
So...
automatic gain control
