Problem: Roman Republic:

Rome's military confederation with the other peoples of the Italian peninsula meant that half of Rome's army was provided by the Socii, such as the Etruscans, Umbrians, Apulians, Campanians, Samnites, Lucani, Bruttii, and the various southern Greek cities. Polybius states that Rome could draw on 770,000 men at the beginning of the Second Punic War, of which 700,000 were infantry and 70,000 met the requirements for cavalry. Rome's Italian allies would be organized in alae, or wings, roughly equal in manpower to the Roman legions, though with 900 cavalry instead of 300.

What allowed Rome to source some of their military from other nearby areas?
---
A: military confederation with the other peoples


Problem: Anthropology:

Waitz defined anthropology as "the science of the nature of man". By nature he meant matter animated by "the Divine breath"; i.e., he was an animist. Following Broca's lead, Waitz points out that anthropology is a new field, which would gather material from other fields, but would differ from them in the use of comparative anatomy, physiology, and psychology to differentiate man from "the animals nearest to him". He stresses that the data of comparison must be empirical, gathered by experimentation. The history of civilization as well as ethnology are to be brought into the comparison. It is to be presumed fundamentally that the species, man, is a unity, and that "the same laws of thought are applicable to all men".

What philosophical perspective did Waitz hold?
---
A: an animist


Problem: Light-emitting diode:

Among the challenges being faced to improve the efficiency of LED-based white light sources is the development of more efficient phosphors. As of 2010, the most efficient yellow phosphor is still the YAG phosphor, with less than 10% Stoke shift loss. Losses attributable to internal optical losses due to re-absorption in the LED chip and in the LED packaging itself account typically for another 10% to 30% of efficiency loss. Currently, in the area of phosphor LED development, much effort is being spent on optimizing these devices to higher light output and higher operation temperatures. For instance, the efficiency can be raised by adapting better package design or by using a more suitable type of phosphor. Conformal coating process is frequently used to address the issue of varying phosphor thickness.

 What is the percentage of stoke shift loss in non-YAG phosphor?
---
A: unanswerable


Problem: Montana:

In 1940, Jeannette Rankin had once again been elected to Congress, and in 1941, as she did in 1917, she voted against the United States' declaration of war. This time she was the only vote against the war, and in the wake of public outcry over her vote, she required police protection for a time. Other pacifists tended to be those from "peace churches" who generally opposed war. Many individuals from throughout the U.S. who claimed conscientious objector status were sent to Montana during the war as smokejumpers and for other forest fire-fighting duties.

What were conscientious objectors sent to Montana to do?
---
A:
smokejumpers and for other forest fire-fighting duties.
