Input: Read this: Through-hole manufacture adds to board cost by requiring many holes to be drilled accurately, and limits the available routing area for signal traces on layers immediately below the top layer on multi-layer boards since the holes must pass through all layers to the opposite side. Once surface-mounting came into use, small-sized SMD components were used where possible, with through-hole mounting only of components unsuitably large for surface-mounting due to power requirements or mechanical limitations, or subject to mechanical stress which might damage the PCB.
Question: What components can be surface mounted to save space?

Output: small-sized SMD components


QUES: Coronis, was daughter of Phlegyas, King of the Lapiths. Pregnant with Asclepius, Coronis fell in love with Ischys, son of Elatus. A crow informed Apollo of the affair. When first informed he disbelieved the crow and turned all crows black (where they were previously white) as a punishment for spreading untruths. When he found out the truth he sent his sister, Artemis, to kill Coronis (in other stories, Apollo himself had killed Coronis). As a result, he also made the crow sacred and gave them the task of announcing important deaths. Apollo rescued the baby and gave it to the centaur Chiron to raise. Phlegyas was irate after the death of his daughter and burned the Temple of Apollo at Delphi. Apollo then killed him for what he did.

Who owas King of the Lapiths?
What is the answer?
ANS: Phlegyas


QUES: Matrix groups consist of matrices together with matrix multiplication. The general linear group GL(n, R) consists of all invertible n-by-n matrices with real entries. Its subgroups are referred to as matrix groups or linear groups. The dihedral group example mentioned above can be viewed as a (very small) matrix group. Another important matrix group is the special orthogonal group SO(n). It describes all possible rotations in n dimensions. Via Euler angles, rotation matrices are used in computer graphics.
What groups combine matrices with matrix multiplication?

ANS: Matrix groups


The Armenian Genocide caused widespread emigration that led to the settlement of Armenians in various countries in the world. Armenians kept to their traditions and certain diasporans rose to fame with their music. In the post-Genocide Armenian community of the United States, the so-called "kef" style Armenian dance music, using Armenian and Middle Eastern folk instruments (often electrified/amplified) and some western instruments, was popular. This style preserved the folk songs and dances of Western Armenia, and many artists also played the contemporary popular songs of Turkey and other Middle Eastern countries from which the Armenians emigrated. Richard Hagopian is perhaps the most famous artist of the traditional "kef" style and the Vosbikian Band was notable in the 40s and 50s for developing their own style of "kef music" heavily influenced by the popular American Big Band Jazz of the time. Later, stemming from the Middle Eastern Armenian diaspora and influenced by Continental European (especially French) pop music, the Armenian pop music genre grew to fame in the 60s and 70s with artists such as Adiss Harmandian and Harout Pamboukjian performing to the Armenian diaspora and Armenia. Also with artists such as Sirusho, performing pop music combined with Armenian folk music in today's entertainment industry. Other Armenian diasporans that rose to fame in classical or international music circles are world-renowned French-Armenian singer and composer Charles Aznavour, pianist Sahan Arzruni, prominent opera sopranos such as Hasmik Papian and more recently Isabel Bayrakdarian and Anna Kasyan. Certain Armenians settled to sing non-Armenian tunes such as the heavy metal band System of a Down (which nonetheless often incorporates traditional Armenian instrumentals and styling into their songs) or pop star Cher. Ruben Hakobyan (Ruben Sasuntsi) is a well recognized Armenian ethnographic and patriotic folk singer who has achieved widespread national recognition due to his devotion to Armenian folk music and exceptional talent. In the Armenian diaspora, Armenian revolutionary songs are popular with the youth.[citation needed] These songs encourage Armenian patriotism and are generally about Armenian history and national heroes.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What type of music does Sirusho perform?
Ah, so.. pop music combined with Armenian folk music


Question: Air defence in naval tactics, especially within a carrier group, is often built around a system of concentric layers with the aircraft carrier at the centre. The outer layer will usually be provided by the carrier's aircraft, specifically its AEW&C aircraft combined with the CAP. If an attacker is able to penetrate this layer, then the next layers would come from the surface-to-air missiles carried by the carrier's escorts; the area-defence missiles, such as the RIM-67 Standard, with a range of up to 100 nmi, and the point-defence missiles, like the RIM-162 ESSM, with a range of up to 30 nmi. Finally, virtually every modern warship will be fitted with small-calibre guns, including a CIWS, which is usually a radar-controlled Gatling gun of between 20mm and 30mm calibre capable of firing several thousand rounds per minute.
Try to answer this question if possible: The next layer's surface-to-air missiles are carried by what?
Answer: the carrier's escorts


Question: On the day of the abdication, the Oireachtas, the parliament of the Irish Free State, removed all direct mention of the monarch from the Irish constitution. The next day, it passed the External Relations Act, which gave the monarch limited authority (strictly on the advice of the government) to appoint diplomatic representatives for Ireland and to be involved in the making of foreign treaties. The two acts made the Irish Free State a republic in essence without removing its links to the Commonwealth.
Try to answer this question if possible: What is the Oireachtas?
Answer:
the parliament of the Irish Free State
