The problem: Answer a question about this article:
The written score, however, does not usually contain explicit instructions as to how to interpret the piece in terms of production or performance, apart from directions for dynamics, tempo and expression (to a certain extent).

What does the written score not usually contain explicitly?

The answer: instructions

Problem: Please answer a question about the following article about Muammar Gaddafi:
Gaddafi organized demonstrations and distributed posters criticizing the monarchy. In October 1961, he led a demonstration protesting Syria's secession from the United Arab Republic. During this they broke windows of a local hotel accused of serving alcohol. Catching the authorities' attention, they expelled his family from Sabha. Gaddafi moved to Misrata, there attending Misrata Secondary School. Maintaining his interest in Arab nationalist activism, he refused to join any of the banned political parties active in the city including the Arab Nationalist Movement, the Arab Socialist Ba'ath Party, and the Muslim Brotherhood claiming he rejected factionalism. He read voraciously on the subjects of Nasser and the French Revolution of 1789, as well as the works of Syrian political theorist Michel Aflaq and biographies of Abraham Lincoln, Sun Yat-sen, and Mustafa Kemal Ataturk.
Gaddafi was an avid reader. Name three biographies that he read.
A: Abraham Lincoln, Sun Yat-sen, and Mustafa Kemal Ataturk

Question: Read this and answer the question

Only one 5.1 surround sound option exists on a given LaserDisc (either Dolby Digital or DTS), so if surround sound is desired, the disc must be matched to the capabilities of the playback equipment (LD Player and Receiver/Decoder) by the purchaser. A fully capable LaserDisc playback system includes a newer LaserDisc player that is capable of playing digital tracks, has a digital optical output for digital PCM and DTS audio, is aware of AC-3 audio tracks, and has an AC-3 coaxial output; an external or internal AC-3 RF demodulator and AC-3 decoder; and a DTS decoder. Many 1990s A/V receivers combine the AC-3 decoder and DTS decoder logic, but an integrated AC-3 demodulator is rare both in LaserDisc players and in later A/V receivers.

How many 5.1 surround sound options exist in LaserDiscs?
Answer: Only one

Problem: Greece, together with Italy and Spain, is a major entry point for illegal immigrants trying to enter the EU. Illegal immigrants entering Greece mostly do so from the border with Turkey at the Evros River and the islands of the eastern Aegean across from Turkey (mainly Lesbos, Chios, Kos, and Samos). In 2012, the majority of illegal immigrants entering Greece came from Afghanistan, followed by Pakistanis and Bangladeshis. In 2015, arrivals of refugees by sea have increased dramatically mainly due to the ongoing Syrian civil war. There were 856,723 arrivals by sea in Greece, an almost fivefold increase to the same period of 2014, of which the Syrians represent almost 45%. An estimated 8% of the arrivals applied for asylum in Greece.
What percentage of sea immigrants asked for asylum in Greece?
The answer is the following: 8%

Manufacturers of devices may have their own proprietary numbering system, for example CK722. Since devices are second-sourced, a manufacturer's prefix (like "MPF" in MPF102, which originally would denote a Motorola FET) now is an unreliable indicator of who made the device. Some proprietary naming schemes adopt parts of other naming schemes, for example a PN2222A is a (possibly Fairchild Semiconductor) 2N2222A in a plastic case (but a PN108 is a plastic version of a BC108, not a 2N108, while the PN100 is unrelated to other xx100 devices).
What is the marking for a 2N2222A in a plastic case?
PN2222A

Here is a question about this article: With the Conference of Berlin of 1884, Portuguese Africa territories had their borders formally established on request of Portugal in order to protect the centuries-long Portuguese interests in the continent from rivalries enticed by the Scramble for Africa. Portuguese Africa's cities and towns like Nova Lisboa, Sa da Bandeira, Silva Porto, Malanje, Tete, Vila Junqueiro, Vila Pery and Vila Cabral were founded or redeveloped inland during this period and beyond. New coastal towns like Beira, Mocamedes, Lobito, Joao Belo, Nacala and Porto Amelia were also founded. Even before the turn of the 20th century, railway tracks as the Benguela railway in Angola, and the Beira railway in Mozambique, started to be built to link coastal areas and selected inland regions.
What is the answer to this question: When were railroad tracks being installed Portugese Africa?
****
So...
before the turn of the 20th century
