Input: Read this: One of the key concerns of older adults is the experience of memory loss, especially as it is one of the hallmark symptoms of Alzheimer's disease. However, memory loss is qualitatively different in normal aging from the kind of memory loss associated with a diagnosis of Alzheimer's (Budson & Price, 2005). Research has revealed that individuals' performance on memory tasks that rely on frontal regions declines with age. Older adults tend to exhibit deficits on tasks that involve knowing the temporal order in which they learned information; source memory tasks that require them to remember the specific circumstances or context in which they learned information; and prospective memory tasks that involve remembering to perform an act at a future time. Older adults can manage their problems with prospective memory by using appointment books, for example.
Question: Older adults can manage their problems with prospective memory by not using what?

Output: unanswerable

Input: Read this: In June 1973, Gaddafi created a political ideology as a basis for the Popular Revolution. Third International Theory considered the U.S. and the Soviet Union as imperialist, thus rejected Western capitalism as well as Eastern bloc communism's atheism.

As part of this theory, Gaddafi praised nationalism as a progressive force and advocated the creation of a pan-Arab state which would lead the Islamic and Third Worlds against imperialism.
Question: What sort of state did Gaddafi believe should be founded?

Output: pan-Arab

Input: Read this: The Illuminating Engineering Society of North America (IESNA), in conjunction with organizations like ANSI and ASHRAE, publishes guidelines, standards, and handbooks that allow categorization of the illumination needs of different built environments. Manufacturers of lighting equipment publish photometric data for their products, which defines the distribution of light released by a specific luminaire. This data is typically expressed in standardized form defined by the IESNA.
Question: Who else publishes along with IESNA?

Output:
ANSI and ASHRAE
