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.

Question: At what point is a channel on in depletion-mode?
Ans: at zero bias


Article: Possibly in part due to expedited federal habeas corpus procedures embodied in the Antiterrorism and Effective Death Penalty Act of 1996, the pace of executions picked up, reaching a peak of 98 in 1999 and then they declined gradually to 28 in 2015. Since the death penalty was reauthorized in 1976, 1,411 people have been executed, almost exclusively by the states, with most occurring after 1990. Texas has accounted for over one-third of modern executions (although only two death sentences were imposed in Texas during 2015, with the courts preferring to issue sentences of life without parole instead) and over four times as many as Oklahoma, the state with the second-highest number. California has the greatest number of prisoners on death row, has issued the highest number of death sentences but has held relatively few executions.

Question: Which state has the largest number of people awaiting execution?
Ans: California


Article: Along with professional services, media companies are concentrated in London and the media distribution industry is London's second most competitive sector. The BBC is a significant employer, while other broadcasters also have headquarters around the City. Many national newspapers are edited in London. London is a major retail centre and in 2010 had the highest non-food retail sales of any city in the world, with a total spend of around £64.2 billion. The Port of London is the second-largest in the United Kingdom, handling 45 million tonnes of cargo each year.

Question: What is the second largest port in the UK?
Ans: The Port of London


Article: In the early 19th century, the Indigenous American woman Sacagawea, who would help translate for and guide the Lewis and Clark Expedition in the West, married the French trapper Toussaint Charbonneau. Most marriages between Europeans and Indigenous Americans were between European men and Indigenous American women. Depending on the kinship system of the woman's tribe, their children would be more or less easily assimilated into the tribe. Nations that had matrilineal systems, such as the Creek and Cherokee in the Southeast, gave the mixed-race children status in their mother's clans and tribes. If the tribe had a patrilineal system, like the Omaha, the children of white fathers were considered white. Unless they were specifically adopted into the tribe by an adult male, they could have no social status in it.

Question: What factor affected the ability of a child to be in a tribe?
Ans:
the kinship system of the woman's tribe
