Problem: The Blitz:

AOC Bomber Command Arthur Harris did see German morale as a major objective. However, he did not believe that the morale-collapse could occur without the destruction of the German economy. The primary goal of Bomber Command's offensives was to destroy the German industrial base (economic warfare), and in doing so reduce morale. In late 1943, just before the Battle of Berlin, he declared the power of Bomber Command would enable it to achieve "a state of devastation in which surrender is inevitable." A summary of Harris' strategic intentions was clear:

What was the primary strategy for Bomber Command offensives?

A: to destroy the German industrial base (economic warfare), and in doing so reduce morale

Problem: Botany:

The light energy captured by chlorophyll a is initially in the form of electrons (and later a proton gradient) that's used to make molecules of ATP and NADPH which temporarily store and transport energy. Their energy is used in the light-independent reactions of the Calvin cycle by the enzyme rubisco to produce molecules of the 3-carbon sugar glyceraldehyde 3-phosphate (G3P). Glyceraldehyde 3-phosphate is the first product of photosynthesis and the raw material from which glucose and almost all other organic molecules of biological origin are synthesized. Some of the glucose is converted to starch which is stored in the chloroplast. Starch is the characteristic energy store of most land plants and algae, while inulin, a polymer of fructose is used for the same purpose in the sunflower family Asteraceae. Some of the glucose is converted to sucrose (common table sugar) for export to the rest of the plant.

Why is table sugar produced?
---
A: for export to the rest of the plant

Problem: Heian period:

Although Kammu had abandoned universal conscription in 792, he still waged major military offensives to subjugate the Emishi, possible descendants of the displaced Jomon, living in northern and eastern Japan. After making temporary gains in 794, in 797 Kammu appointed a new commander, Sakanoue no Tamuramaro, under the title Sei-i Taishogun (Barbarian-subduing generalissimo). By 801 the shogun had defeated the Emishi and had extended the imperial domains to the eastern end of Honshu. Imperial control over the provinces was tenuous at best, however. In the ninth and tenth centuries, much authority was lost to the great families, who disregarded the Chinese-style land and tax systems imposed by the government in Kyoto. Stability came to Japan, but, even though succession was ensured for the imperial family through heredity, power again concentrated in the hands of one noble family, the Fujiwara which also helped Japan develop more.

What was the name of the possible descendants of Jomon?
---
A: Emishi

Problem: Anti-aircraft warfare:

Another potential weapon system for anti-aircraft use is the laser. Although air planners have imagined lasers in combat since the late 1960s, only the most modern laser systems are currently reaching what could be considered "experimental usefulness". In particular the Tactical High Energy Laser can be used in the anti-aircraft and anti-missile role. If current developments continue, some[who?] believe it is reasonable to suggest that lasers will play a major role in air defence starting in the next ten years.

When do some people believe that lasers can play a more prominent role in air defence?
---
A:
in the next ten years
