Input: Article: Definitions of "Southeast Asia" vary, but most definitions include the area represented by the countries (sovereign states and dependent territories) listed below. All of the states except for East Timor are members of the Association of Southeast Asian Nations (ASEAN). The area, together with part of South Asia, was widely known as the East Indies or simply the Indies until the 20th century. Christmas Island and the Cocos (Keeling) Islands[citation needed] are considered part of Southeast Asia though they are governed by Australia.[citation needed] Sovereignty issues exist over some territories in the South China Sea. Papua New Guinea has stated that it might join ASEAN, and is currently an observer.

Now answer this question: What type of issue exist over the territories in the South China sea?

Output: Sovereignty

Input: Article: While exploring inland along the northern coast of Florida in 1528, the members of the Narvaez expedition, including Alvar Nunez Cabeza de Vaca, found a Native American village near present-day Tallahassee, Florida whose name they transcribed as Apalchen or Apalachen [a.pala.tn]. The name was soon altered by the Spanish to Apalachee and used as a name for the tribe and region spreading well inland to the north. Panfilo de Narvaez's expedition first entered Apalachee territory on June 15, 1528, and applied the name. Now spelled "Appalachian," it is the fourth-oldest surviving European place-name in the US.

Now answer this question: What was the name eventually used for?

Output: as a name for the tribe and region spreading well inland to the north

Input: Article: FETs are further divided into depletion-mode and enhancement-mode types, depending on whether the channel is turned on or off with zero gate-to-source voltage. For enhancement mode, the channel is off at zero bias, and a gate potential can "enhance" the conduction. For the depletion mode, the channel is on at zero bias, and a gate potential (of the opposite polarity) can "deplete" the channel, reducing conduction. For either mode, a more positive gate voltage corresponds to a higher current for n-channel devices and a lower current for p-channel devices. Nearly all JFETs are depletion-mode because the diode junctions would forward bias and conduct if they were enhancement-mode devices; most IGFETs are enhancement-mode types.

Now answer this question: How are FET's separated?

Output:
depletion-mode and enhancement-mode types
