Context and question: Three Han mathematical treatises still exist. These are the Book on Numbers and Computation, the Arithmetical Classic of the Gnomon and the Circular Paths of Heaven and the Nine Chapters on the Mathematical Art. Han-era mathematical achievements include solving problems with right-angle triangles, square roots, cube roots, and matrix methods, finding more accurate approximations for pi, providing mathematical proof of the Pythagorean theorem, use of the decimal fraction, Gaussian elimination to solve linear equations, and continued fractions to find the roots of equations.
What achievement of the Han era can be used to help solve linear equations?
Answer: Gaussian elimination
Context and question: Investment in the city continued. The William Enston Home, a planned community for the city's aged and infirm, was built in 1889. An elaborate public building, the United States Post Office and Courthouse, was completed by the federal government in 1896 in the heart of the city. The Democrat-dominated state legislature passed a new constitution in 1895 that disfranchised blacks, effectively excluding them entirely from the political process, a second-class status that was maintained for more than six decades in a state that was majority black until about 1930.
Which party dominated North Carolina's state legislature?
Answer: unanswerable
Context and question: 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?
Answer:
unanswerable
