Input: Read this: Most historians[who?] consider Caliph Muawiyah (661–80) to have been the second ruler of the Umayyad dynasty, even though he was the first to assert the Umayyads' right to rule on a dynastic principle. It was really the caliphate of Uthman Ibn Affan (644–656), a member of Umayyad clan himself, that witnessed the revival and then the ascendancy of the Umayyad clan to the corridors of power. Uthman placed some of the trusted members of his clan at prominent and strong positions throughout the state. Most notable was the appointment of Marwan ibn al-Hakam, Uthman's first cousin, as his top advisor, which created a stir among the Hashimite companions of Muhammad, as Marwan along with his father Al-Hakam ibn Abi al-'As had been permanently exiled from Medina by Muhammad during his lifetime. Uthman also appointed as governor of Kufa his half-brother, Walid ibn Uqba, who was accused by Hashmites of leading prayer while under the influence of alcohol. Uthman also consolidated Muawiyah's governorship of Syria by granting him control over a larger area and appointed his foster brother Abdullah ibn Saad as the Governor of Egypt. However, since Uthman never named an heir, he cannot be considered the founder of a dynasty.
Question: Who was Marwan ibn al-Hakam'a top advisor?

Output: unanswerable


QUES: The Logic and Metaphysics have been extensively reprinted, the latter, e.g., at Venice in 1493, 1495, and 1546. Some of his shorter essays on medicine, logic, etc., take a poetical form (the poem on logic was published by Schmoelders in 1836).[citation needed] Two encyclopaedic treatises, dealing with philosophy, are often mentioned. The larger, Al-Shifa' (Sanatio), exists nearly complete in manuscript in the Bodleian Library and elsewhere; part of it on the De Anima appeared at Pavia (1490) as the Liber Sextus Naturalium, and the long account of Ibn Sina's philosophy given by Muhammad al-Shahrastani seems to be mainly an analysis, and in many places a reproduction, of the Al-Shifa'. A shorter form of the work is known as the An-najat (Liberatio). The Latin editions of part of these works have been modified by the corrections which the monastic editors confess that they applied. There is also a حكمت مشرقيه (hikmat-al-mashriqqiyya, in Latin Philosophia Orientalis), mentioned by Roger Bacon, the majority of which is lost in antiquity, which according to Averroes was pantheistic in tone.

What is the shorter form of Al-Shifa called?
What is the answer?
ANS: the An-najat


QUES: In 1972, the French physicist Francis Perrin discovered fifteen ancient and no longer active natural nuclear fission reactors in three separate ore deposits at the Oklo mine in Gabon, West Africa, collectively known as the Oklo Fossil Reactors. The ore deposit is 1.7 billion years old; then, uranium-235 constituted about 3% of the total uranium on Earth. This is high enough to permit a sustained nuclear fission chain reaction to occur, provided other supporting conditions exist. The capacity of the surrounding sediment to contain the nuclear waste products has been cited by the U.S. federal government as supporting evidence for the feasibility to store spent nuclear fuel at the Yucca Mountain nuclear waste repository.
Of what nationality wasn't Perrin?

Question: There are special rules for certain rare diseases ("orphan diseases") in several major drug regulatory territories. For example, diseases involving fewer than 200,000 patients in the United States, or larger populations in certain circumstances are subject to the Orphan Drug Act.  Because medical research and development of drugs to treat such diseases is financially disadvantageous, companies that do so are rewarded with tax reductions, fee waivers, and market exclusivity on that drug for a limited time (seven years), regardless of whether the drug is protected by patents.
Try to answer this question if possible: Why are these companies rewarded?
Answer: Because medical research and development of drugs to treat such diseases is financially disadvantageous


Input: Read this: To improve the efficiency of the lamp, the filament usually consists of multiple coils of coiled fine wire, also known as a 'coiled coil'. For a 60-watt 120-volt lamp, the uncoiled length of the tungsten filament is usually 22.8 inches (580 mm), and the filament diameter is 0.0018 inches (0.046 mm). The advantage of the coiled coil is that evaporation of the tungsten filament is at the rate of a tungsten cylinder having a diameter equal to that of the coiled coil. The coiled-coil filament evaporates more slowly than a straight filament of the same surface area and light-emitting power. As a result, the filament can then run hotter, which results in a more efficient light source, while reducing the evaporation so that the filament will last longer than a straight filament at the same temperature.
Question: What did not improve efficiency of the lamp?
