Problem: Bacteria:

Many important biochemical reactions, such as energy generation, use concentration gradients across membranes. The general lack of internal membranes in bacteria means reactions such as electron transport occur across the cell membrane between the cytoplasm and the periplasmic space. However, in many photosynthetic bacteria the plasma membrane is highly folded and fills most of the cell with layers of light-gathering membrane. These light-gathering complexes may even form lipid-enclosed structures called chlorosomes in green sulfur bacteria. Other proteins import nutrients across the cell membrane, or expel undesired molecules from the cytoplasm.

What is crucial for biochemical reactions?

A: concentration gradients across membranes

Problem: In 1999, there was a double homicide in the Westside Clothing store on Lincoln Boulevard. During the incident, Culver City gang members David "Puppet" Robles and Jesse "Psycho" Garcia entered the store masked and began opening fire, killing Anthony and Michael Juarez. They then ran outside to a getaway vehicle driven by a third Culver City gang member, who is now also in custody. The clothing store was believed to be a local hang out for Santa Monica gang members. The dead included two men from Northern California who had merely been visiting the store's owner, their cousin, to see if they could open a similar store in their area. Police say the incident was in retaliation for a shooting committed by the Santa Monica 13 gang days before the Juarez brothers were gunned down.
Where is the getaway driver of the Culver city gang murder?

Answer: in custody

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Democratic Party candidates were consistently elected to local office, increasing the city's ties to the South and its dominant party. In 1861, Mayor Fernando Wood called on the aldermen to declare independence from Albany and the United States after the South seceded, but his proposal was not acted on. Anger at new military conscription laws during the American Civil War (18611865), which spared wealthier men who could afford to pay a $300 (equivalent to $5,766 in 2016) commutation fee to hire a substitute, led to the Draft Riots of 1863, whose most visible participants were ethnic Irish working class. The situation deteriorated into attacks on New York's elite, followed by attacks on black New Yorkers and their property after fierce competition for a decade between Irish immigrants and blacks for work. Rioters burned the Colored Orphan Asylum to the ground, but more than 200 children escaped harm due to efforts of the New York City Police Department, which was mainly made up of Irish immigrants. According to historian James M. McPherson (2001), at least 120 people were killed. In all, eleven black men were lynched over five days, and the riots forced hundreds of blacks to flee the city for Williamsburg, Brooklyn, as well as New Jersey; the black population in Manhattan fell below 10,000 by 1865, which it had last been in 1820. The white working class had established dominance. Violence by longshoremen against black men was especially fierce in the docks area. It was one of the worst incidents of civil unrest in American history.
What was the approximate African-American population of New York City in 1865?
A: 10,000

Context and question: In the last two weeks of February 1951, Operation Roundup was followed by Operation Killer, carried out by the revitalized Eighth Army. It was a full-scale, battlefront-length attack staged for maximum exploitation of firepower to kill as many KPA and PVA troops as possible. Operation Killer concluded with I Corps re-occupying the territory south of the Han River, and IX Corps capturing Hoengseong. On 7 March 1951, the Eighth Army attacked with Operation Ripper, expelling the PVA and the KPA from Seoul on 14 March 1951. This was the city's fourth conquest in a years' time, leaving it a ruin; the 1.5 million pre-war population was down to 200,000, and people were suffering from severe food shortages.
What signified the end of Operation Killer?
Answer: capturing Hoengseong

Question: In about 319, when Athanasius was a deacon, a presbyter named Arius came into a direct conflict with Alexander of Alexandria. It appears that Arius reproached Alexander for what he felt were misguided or heretical teachings being taught by the bishop. Arius's theological views appear to have been firmly rooted in Alexandrian Christianity, and his Christological views were certainly not radical at all. He embraced a subordinationist Christology which taught that Christ was the divine Son (Logos) of God, made, not begotten, heavily influenced by Alexandrian thinkers like Origen, and which was a common Christological view in Alexandria at the time. Support for Arius from powerful bishops like Eusebius of Caesarea and Eusebius of Nicomedia, further illustrate how Arius's subordinationist Christology was shared by other Christians in the Empire. Arius was subsequently excommunicated by Alexander, and he would begin to elicit the support of many bishops who agreed with his position.
Is there an answer to this question: When did Athanasius become a deacon?

Answer: unanswerable

A synchronous electric motor is an AC motor distinguished by a rotor spinning with coils passing magnets at the same rate as the AC and resulting magnetic field which drives it. Another way of saying this is that it has zero slip under usual operating conditions. Contrast this with an induction motor, which must slip to produce torque. One type of synchronous motor is like an induction motor except the rotor is excited by a DC field. Slip rings and brushes are used to conduct current to the rotor. The rotor poles connect to each other and move at the same speed hence the name synchronous motor. Another type, for low load torque, has flats ground onto a conventional squirrel-cage rotor to create discrete poles. Yet another, such as made by Hammond for its pre-World War II clocks, and in the older Hammond organs, has no rotor windings and discrete poles. It is not self-starting. The clock requires manual starting by a small knob on the back, while the older Hammond organs had an auxiliary starting motor connected by a spring-loaded manually operated switch.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How isn't current brought to the rotor in a synchronous motor?
Ah, so..
