QUES: The Sanskrit grammatical tradition, Vyakarana, one of the six Vedangas, began in the late Vedic period and culminated in the Astadhyayi of Panini, which consists of 3990 sutras (ca. fifth century BCE). About a century after Panini (around 400 BCE), Katyayana composed Vartikas on the Panini sutras. Patanjali, who lived three centuries after Panini, wrote the Mahabhasya, the "Great Commentary" on the Astadhyayi and Vartikas. Because of these three ancient Vyakaranins (grammarians), this grammar is called Trimuni Vyakarana. To understand the meaning of the sutras, Jayaditya and Vamana wrote a commentary, the Kasika, in 600 CE. Paninian grammar is based on 14 Shiva sutras (aphorisms), where the whole matrika (alphabet) is abbreviated. This abbreviation is called the Pratyahara.
Who lived three centuries before Panini?

ANS: unanswerable

QUES: With respect to Pakistan's territories (i.e. FATA, Azad Kashmir, Northern Areas and Islamabad Capital Territory (ICT)) the Supreme Court's jurisdiction is rather limited and varies from territory to territory; it can hear appeals only of a constitutional nature from FATA and Northern Areas, while ICT generally functions the same as provinces. Azad Kashmir has its own courts system and the constitution of Pakistan does not apply to it as such; appeals from Azad Kashmir relate to its relationship with Pakistan.
What are some of the territories within Pakistan?

ANS: FATA, Azad Kashmir, Northern Areas and Islamabad Capital Territory (ICT)

QUES: The thermionic triode, a vacuum tube invented in 1907, enabled amplified radio technology and long-distance telephony. The triode, however, was a fragile device that consumed a lot of power. Physicist Julius Edgar Lilienfeld filed a patent for a field-effect transistor (FET) in Canada in 1925, which was intended to be a solid-state replacement for the triode. Lilienfeld also filed identical patents in the United States in 1926 and 1928. However, Lilienfeld did not publish any research articles about his devices nor did his patents cite any specific examples of a working prototype. Because the production of high-quality semiconductor materials was still decades away, Lilienfeld's solid-state amplifier ideas would not have found practical use in the 1920s and 1930s, even if such a device had been built. In 1934, German inventor Oskar Heil patented a similar device.
Where did Lilienfeld file his patent?

ANS: Canada

QUES: 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.
When were the prisoners set free?

ANS:
February 7, 1987,
