Problem: Buddhism:

Much of the early extant evidence for the origins of Mahayana comes from early Chinese translations of Mahayana texts. These Mahayana teachings were first propagated into China by Lokaksema, the first translator of Mahayana sutras into Chinese during the 2nd century CE.[note 39] Some scholars have traditionally considered the earliest Mahayana sutras to include the very first versions of the Prajnaparamita series, along with texts concerning Aksobhya Buddha, which were probably composed in the 1st century BCE in the south of India.[note 40]

The Mahayana teachings were first propagated into China by who?

A: Lokaksema

Problem: Although NPOs are permitted to generate surplus revenues, they must be retained by the organization for its self-preservation, expansion, or plans. NPOs have controlling members or a board of directors. Many have paid staff including management, whereas others employ unpaid volunteers and even executives who work with or without compensation (occasionally nominal). In some countries, where there is a token fee, in general it is used to meet legal requirements for establishing a contract between the executive and the organization.
What do NPO's use their surplus fees for?

On the French side, planning after the disaster at Wissembourg had become essential. General Le Buf, flushed with anger, was intent upon going on the offensive over the Saar and countering their loss. However, planning for the next encounter was more based upon the reality of unfolding events rather than emotion or pride, as Intendant General Wolff told him and his staff that supply beyond the Saar would be impossible. Therefore, the armies of France would take up a defensive position that would protect against every possible attack point, but also left the armies unable to support each other.
Which general was determined to go on the attack over Saar?
A: General Le Buf

Context and question: The D-Day Normandy landings on June 6, 1944, were costly but successful. A month later, the invasion of Southern France took place, and control of forces in the southern invasion passed from the AFHQ to the SHAEF. Many prematurely considered that victory in Europe would come by summer's endhowever the Germans did not capitulate for almost a year. From then until the end of the war in Europe on May 8, 1945, Eisenhower, through SHAEF, commanded all Allied forces, and through his command of ETOUSA had administrative command of all U.S. forces on the Western Front north of the Alps. He was ever mindful of the inevitable loss of life and suffering that would be experienced on an individual level by the troops under his command and their families. This prompted him to make a point of visiting every division involved in the invasion. Eisenhower's sense of responsibility was underscored by his draft of a statement to be issued if the invasion failed. It has been called one of the great speeches of history:
When did the Normandy invasion occur?
Answer: June 6, 1944

Question: In the Soviet Union, in the 1970s, a comparison was made between systems electrified at 3 kV DC and 25 kV AC (50 Hz). The results showed that percentage losses in the overhead wires (catenary and contact wires) was over 3 times greater for 3 kV DC than for 25 kV AC. But when the conversion losses were all taken into account and added to overhead wire losses (including cooling blower energy) the 25 kV AC lost a somewhat higher percent of energy than for 3 kV DC. Thus in spite of the much higher losses in the catenary, the 3 kV DC was a little more energy efficient than AC in providing energy from the USSR power grid to the terminals of the traction motors (all DC at that time). While both systems use energy in converting higher voltage AC from the USSR's power grid to lower voltage DC, the conversions for the DC system all took place (at higher efficiency) in the railway substation, while most of the conversion for the AC system took place inside the locomotive (at lower efficiency). Consider also that it takes energy to constantly move this mobile conversion hardware over the rails while the stationary hardware in the railway substation doesn't incur this energy cost. For more details see: Wiki: Soviet Union DC vs. AC.
Is there an answer to this question: The conversion for what system took place in the railway station?

Answer: unanswerable

The CIPA DC-004 standard requires that Japanese manufacturers of digital still cameras use either the REI or SOS techniques, and DC-008 updates the Exif specification to differentiate between these values. Consequently, the three EI techniques carried over from ISO 12232:1998 are not widely used in recent camera models (approximately 2007 and later). As those earlier techniques did not allow for measurement from images produced with lossy compression, they cannot be used at all on cameras that produce images only in JPEG format.
The three EI techniques have to be used on cameras that only capture in what format?
A:
unanswerable
