Problem: Question: "What is the goal of electrons and holes moving into the quantum dot layer?" Context: "The structure of QD-LEDs used for the electrical-excitation scheme is similar to basic design of OLEDs. A layer of quantum dots is sandwiched between layers of electron-transporting and hole-transporting materials. An applied electric field causes electrons and holes to move into the quantum dot layer and recombine forming an exciton that excites a QD. This scheme is commonly studied for quantum dot display. The tunability of emission wavelengths and narrow bandwidth is also beneficial as excitation sources for fluorescence imaging. Fluorescence near-field scanning optical microscopy (NSOM) utilizing an integrated QD-LED has been demonstrated." Answer:

A: excites a QD

Problem: Given the question: Question: "What is the primary action taken for the psychological factors caused by pain" Context: "Pain is the most common reason for physician consultation in most developed countries. It is a major symptom in many medical conditions, and can interfere with a person's quality of life and general functioning.

input question: Question: "Criminals weren't deterred by?" Context: "The Fujiwara rulers failed to maintain adequate police forces, which left robbers free to prey on travelers. This is implicitly illustrated in novels by the terror that night travel inspired in the main characters. The shoen system enabled the accumulation of wealth by an aristocratic elite; the economic surplus can be linked to the cultural developments of the Heian period and the "pursuit of arts". The major Buddhist temples in Heian-kyo and Nara also made use of the shoen. The establishment of branches rurally and integration of some Shinto shrines within these temple networks reflects a greater "organizational dynamism"." Answer:???
output answer: police forces

Question: "Who had power in both cities and countryside after the failed uprising that ended in 1345?" Context: "From 1228, after of the Livonian Crusade, through the 1560s, Estonia was part of Terra Mariana, established on 2 February 1207 as a principality of the Holy Roman Empire and proclaimed by Pope Innocent III in 1215 as subject to the Holy See. The southern parts of the country were conquered by Livonian Brothers of the Sword who joined the Teutonic Order in 1237 and became its branch known as the Livonian Order. The Duchy of Estonia was created out of the northern parts of the country and was a direct dominion of the King of Denmark from 1219 until 1346, when it was sold to the Teutonic Order and became part of the Ordenstaat. In 1343, the people of northern Estonia and Saaremaa rebelled against German rule in the St. George's Night Uprising, which was put down by 1345. The unsuccessful rebellion led to a consolidation of power for the Baltic German minority. For the subsequent centuries they remained the ruling elite in both cities and in the countryside." Answer:
----
Answer: Baltic German minority

Q: Question: "Which state had the highest rate in the southern portion of the US for the number of adults with a high school diploma?" Context: "The state is among the best in pre-kindergarten education, and the National Institute for Early Education Research rated it first in the United States with regard to standards, quality, and access to pre-kindergarten education in 2004, calling it a model for early childhood schooling. High school dropout rate decreased from 3.1 to 2.5 percent between 2007 and 2008 with Oklahoma ranked among 18 other states with 3 percent or less dropout rate. In 2004, the state ranked 36th in the nation for the relative number of adults with high school diplomas, though at 85.2 percent, it had the highest rate among southern states." Answer:
A: Oklahoma

[Q]: Question: "What are these elevators most helpful in doing?" Context: "A climbing elevator is a self-ascending elevator with its own propulsion. The propulsion can be done by an electric or a combustion engine. Climbing elevators are used in guyed masts or towers, in order to make easy access to parts of these constructions, such as flight safety lamps for maintenance. An example would be the Moonlight towers in Austin, Texas, where the elevator holds only one person and equipment for maintenance. The Glasgow Tower an observation tower in Glasgow, Scotland also makes use of two climbing elevators." Answer:
****
[A]:
access to parts
