Question: Gellius says that in his day humanitas is commonly used as a synonym for philanthropy – or kindness and benevolence toward one's fellow human being. Gellius maintains that this common usage is wrong, and that model writers of Latin, such as Cicero and others, used the word only to mean what we might call "humane" or "polite" learning, or the Greek equivalent Paideia. Gellius became a favorite author in the Italian Renaissance, and, in fifteenth-century Italy, teachers and scholars of philosophy, poetry, and rhetoric were called and called themselves "humanists". Modern scholars, however, point out that Cicero (106 – 43 BCE), who was most responsible for defining and popularizing the term humanitas, in fact frequently used the word in both senses, as did his near contemporaries. For Cicero, a lawyer, what most distinguished humans from brutes was speech, which, allied to reason, could (and should) enable them to settle disputes and live together in concord and harmony under the rule of law. Thus humanitas included two meanings from the outset and these continue in the modern derivative, humanism, which even today can refer to both humanitarian benevolence and to scholarship.

Question: The Sanskrit grammatical tradition, Vyākaraṇa, one of the six Vedangas, began in the late Vedic period and culminated in the Aṣṭādhyāyī of Pāṇini, which consists of 3990 sutras (ca. fifth century BCE). About a century after Pāṇini (around 400 BCE), Kātyāyana composed Vārtikas on the Pāṇini sũtras. Patanjali, who lived three centuries after Pāṇini, wrote the Mahābhāṣya, the "Great Commentary" on the Aṣṭādhyāyī and Vārtikas. Because of these three ancient Vyākaraṇins (grammarians), this grammar is called Trimuni Vyākarana. To understand the meaning of the sutras, Jayaditya and Vāmana wrote a commentary, the Kāsikā, in 600 CE. Pāṇinian grammar is based on 14 Shiva sutras (aphorisms), where the whole mātrika (alphabet) is abbreviated. This abbreviation is called the Pratyāhara.

Answer: late Vedic
Question: In recent decades, a series of inscribed graphs and pictures have been found at Neolithic sites in China, including Jiahu (c. 6500 BC), Dadiwan and Damaidi from the 6th millennium BC, and Banpo (5th millennium BC). Often these finds are accompanied by media reports that push back the purported beginnings of Chinese writing by thousands of years. However, because these marks occur singly, without any implied context, and are made crudely and simply, Qiu Xigui concluded that "we do not have any basis for stating that these constituted writing nor is there reason to conclude that they were ancestral to Shang dynasty Chinese characters." They do however demonstrate a history of sign use in the Yellow River valley during the Neolithic through to the Shang period.

Answer: series of inscribed graphs and pictures
Question: On February 7, 1987, dozens of political prisoners were freed in the first group release since Khrushchev's "thaw" in the mid-1950s. On May 6, 1987, Pamyat, a Russian nationalist group, held an unsanctioned demonstration in Moscow. The authorities did not break up the demonstration and even kept traffic out of the demonstrators' way while they marched to an impromptu meeting with Boris Yeltsin, head of the Moscow Communist Party and at the time one of Gorbachev's closest allies. On July 25, 1987, 300 Crimean Tatars staged a noisy demonstration near the Kremlin Wall for several hours, calling for the right to return to their homeland, from which they were deported in 1944; police and soldiers merely looked on.
