TASK DEFINITION: Given a paragraph from a Wikipedia article about some topic, and a question related to the topic, determine whether the question is answerable from the paragraph. If the question is answerable, answer "True", otherwise, answer "False".
PROBLEM: 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. Question: What display is more energy efficient?

SOLUTION: False

PROBLEM: General Dong Zhuo (d. 192 AD) found the young emperor and his brother wandering in the countryside. He escorted them safely back to the capital and was made Minister of Works, taking control of Luoyang and forcing Yuan Shao to flee. After Dong Zhuo demoted Emperor Shao and promoted his brother Liu Xie as Emperor Xian, Yuan Shao led a coalition of former officials and officers against Dong, who burned Luoyang to the ground and resettled the court at Chang'an in May 191 AD. Dong Zhuo later poisoned Emperor Shao. Question: Which of the following was a city: Shao, Luoyang or Dong?

SOLUTION: True

PROBLEM: In Bern, about 50,418 or (39.2%) of the population have completed non-mandatory upper secondary education, and 24,311 or (18.9%) have completed additional higher education (either university or a Fachhochschule). Of the 24,311 who completed tertiary schooling, 51.6% were Swiss men, 33.0% were Swiss women, 8.9% were non-Swiss men and 6.5% were non-Swiss women. Question: Of the four groups of people who completed tertiary schooling, which group was the third largest?

SOLUTION:
True
