The word qur'an appears about 70 times in the Quran itself, assuming various meanings. It is a verbal noun (masdar) of the Arabic verb qara'a (), meaning "he read" or "he recited". The Syriac equivalent is () qeryana, which refers to "scripture reading" or "lesson". While some Western scholars consider the word to be derived from the Syriac, the majority of Muslim authorities hold the origin of the word is qara'a itself. Regardless, it had become an Arabic term by Muhammad's lifetime. An important meaning of the word is the "act of reciting", as reflected in an early Quranic passage: "It is for Us to collect it and to recite it (qur'anahu)."
The words from which the name "Quran" might be described are unrelated to which act?
A: unanswerable

In 1807, Thomas Young was possibly the first to use the term "energy" instead of vis viva, in its modern sense. Gustave-Gaspard Coriolis described "kinetic energy" in 1829 in its modern sense, and in 1853, William Rankine coined the term "potential energy". The law of conservation of energy was also first postulated in the early 19th century, and applies to any isolated system. It was argued for some years whether heat was a physical substance, dubbed the caloric, or merely a physical quantity, such as momentum. In 1845 James Prescott Joule discovered the link between mechanical work and the generation of heat.
Who rejected the term "potential energy?"
A: unanswerable

Italy is home to a vast array of native regional minority languages, most of which are Romance-based and have their own local variants. These regional languages are often referred to colloquially or in non-linguistic circles as Italian "dialects," or dialetti (standard Italian for "dialects"). However, the majority of the regional languages in Italy are in fact not actually "dialects" of standard Italian in the strict linguistic sense, as they are not derived from modern standard Italian but instead evolved locally from Vulgar Latin independent of standard Italian, with little to no influence from what is now known as "standard Italian." They are therefore better classified as individual languages rather than "dialects."
What does 'dialetti' mean in Italian?
A: dialects
