Problem: Light-emitting diode:

Recent developments in LEDs permit them to be used in environmental and task lighting. LEDs have many advantages over incandescent light sources including lower energy consumption, longer lifetime, improved physical robustness, smaller size, and faster switching. Light-emitting diodes are now used in applications as diverse as aviation lighting, automotive headlamps, advertising, general lighting, traffic signals, camera flashes and lighted wallpaper. As of 2015[update], LEDs powerful enough for room lighting remain somewhat more expensive, and require more precise current and heat management, than compact fluorescent lamp sources of comparable output.

Problem: For English Dominican mystics, the mystical experience was not expressed just in one moment of the full knowledge of God, but in the journey of, or process of, faith. This then led to an understanding that was directed toward an experiential knowledge of divinity. It is important to understand, however, that for these mystics it was possible to pursue mystical life without the visions and voices that are usually associated with such a relationship with God. They experienced a mystical process that allowed them, in the end, to experience what they had already gained knowledge of through their faith only.
What does the process of faith not led one to?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The Macintosh (/ˈmækᵻntɒʃ/ MAK-in-tosh; branded as Mac since 1997) is a series of personal computers (PCs) designed, developed, and marketed by Apple Inc. Steve Jobs introduced the original Macintosh computer on January 24, 1984. This was the first mass-market personal computer featuring an integral graphical user interface and mouse. This first model was later renamed to "Macintosh 128k" for uniqueness amongst a populous family of subsequently updated models which are also based on Apple's same proprietary architecture. Since 1998, Apple has largely phased out the Macintosh name in favor of "Mac", though the product family has been nicknamed "Mac" or "the Mac" since the development of the first model.
What did Steve Jobs introduce on January 24, 1988?
A: unanswerable


Context and question: At the beginning of the Caliphate or Islamic Empire, the reliance on courts initially confined sponsorship and scholarly activities to major centres. Within several centuries, the development of Muslim educational institutions such as the madrasah and masjid eventually introduced such activities to provincial towns and dispersed them across the Islamic legal schools and Sufi orders. In addition to religious subjects, they also taught the "rational sciences," as varied as mathematics, astronomy, astrology, geography, alchemy, philosophy, magic, and occultism, depending on the curriculum of the specific institution in question. The madaris, however, were not centres of advanced scientific study; scientific advances in Islam were usually carried out by scholars working under the patronage of royal courts. During this time,[when?] the Caliphate experienced a growth in literacy, having the highest literacy rate of the Middle Ages, comparable to classical Athens' literacy in antiquity but on a much larger scale. The emergence of the maktab and madrasa institutions played a fundamental role in the relatively high literacy rates of the medieval Islamic world.
What group of people had the highest literacy rates during the Middle Ages?
Answer: Caliphate


Question: Medieval political philosophy in Europe was heavily influenced by Christian thinking. It had much in common with the Mutazalite Islamic thinking in that the Roman Catholics though subordinating philosophy to theology did not subject reason to revelation but in the case of contradictions, subordinated reason to faith as the Asharite of Islam. The Scholastics by combining the philosophy of Aristotle with the Christianity of St. Augustine emphasized the potential harmony inherent in reason and revelation. Perhaps the most influential political philosopher of medieval Europe was St. Thomas Aquinas who helped reintroduce Aristotle's works, which had only been transmitted to Catholic Europe through Muslim Spain, along with the commentaries of Averroes. Aquinas's use of them set the agenda, for scholastic political philosophy dominated European thought for centuries even unto the Renaissance.
Is there an answer to this question: Who emphasize the harmony absent in reason and revelation?

Answer: unanswerable

The most interesting morality play is The Castle of Perseverance which depicts mankind's progress from birth to death.
