QUES: Carpet-weaving is historically a major traditional profession for the majority of Armenian women, including many Armenian families. Prominent Karabakh carpet weavers there were men too. The oldest extant Armenian carpet from the region, referred to as Artsakh (see also Karabakh carpet) during the medieval era, is from the village of Banants (near Gandzak) and dates to the early 13th century. The first time that the Armenian word for carpet, gorg, was used in historical sources was in a 12421243 Armenian inscription on the wall of the Kaptavan Church in Artsakh.
Where is the earliest known use of 'gorg'?

ANS: in a 12421243 Armenian inscription on the wall of the Kaptavan Church in Artsakh

QUES: In 2002, the Musharraf-led government took a firm stand against the jihadi organizations and groups promoting extremism, and arrested Maulana Masood Azhar, head of the Jaish-e-Mohammed, and Hafiz Muhammad Saeed, chief of the Lashkar-e-Taiba, and took dozens of activists into custody. An official ban was imposed on the groups on 12 January. Later that year, the Saudi born Zayn al-Abidn Muhammed Hasayn Abu Zubaydah was arrested by Pakistani officials during a series of joint U.S.-Pakistan raids. Zubaydah is said to have been a high-ranking al-Qaeda official with the title of operations chief and in charge of running al-Qaeda training camps. Other prominent al-Qaeda members were arrested in the following two years, namely Ramzi bin al-Shibh, who is known to have been a financial backer of al-Qaeda operations, and Khalid Sheikh Mohammed, who at the time of his capture was the third highest-ranking official in al-Qaeda and had been directly in charge of the planning for the 11 September attacks.
What was the rank of Ramzi bin al-Shibh?

ANS: unanswerable

QUES: In 2001, Comcast announced it would acquire the assets of the largest cable television operator at the time, AT&T Broadband, for US$44.5 billion. The proposed name for the merged company was "AT&T Comcast", but the companies ultimately decided to keep only the Comcast name. In 2002, Comcast acquired all assets of AT&T Broadband, thus making Comcast the largest cable television company in the United States with over 22 million subscribers. This also spurred the start of Comcast Advertising Sales (using AT&T's groundwork) which would later be renamed Comcast Spotlight. As part of this acquisition, Comcast also acquired the National Digital Television Center in Centennial, Colorado as a wholly owned subsidiary, which is today known as the Comcast Media Center.
When Comcast purchased AT&T Broadband, how many customers did they service?

ANS: 22 million

QUES: The most common symptom of LED (and diode laser) failure is the gradual lowering of light output and loss of efficiency. Sudden failures, although rare, can also occur. Early red LEDs were notable for their short service life. With the development of high-power LEDs the devices are subjected to higher junction temperatures and higher current densities than traditional devices. This causes stress on the material and may cause early light-output degradation. To quantitatively classify useful lifetime in a standardized manner it has been suggested to use L70 or L50, which are the runtimes (typically given in thousands of hours) at which a given LED reaches 70% and 50% of initial light output, respectively.
What could cause early light-output degradation in LEDs?

ANS:
higher junction temperatures
