Context: A stepper is a device used in the manufacture of integrated circuits (ICs) that is similar in operation to a slide projector or a photographic enlarger. Steppers are an essential part of the complex process, called photolithography, that creates millions of microscopic circuit elements on the surface of tiny chips of silicon. These chips form the heart of ICs such as computer processors, memory chips, and many other devices., Pentax () is a brand name used primarily by Ricoh Imaging Company for cameras, sport optics (including binoculars and rifle scopes), and CCTV optics. The brand is also used by Hoya Corporation for medical products & services, TI Asahi for surveying instruments, and Seiko Optical Products for certain optical lenses., A camera lens (also known as photographic lens or photographic objective) is an optical lens or assembly of lenses used in conjunction with a camera body and mechanism to make images of objects either on photographic film or on other media capable of storing an image chemically or electronically., The Nikon F camera, introduced in April 1959, was Nikon's first SLR camera. It was one of the most advanced cameras of its day. Although many of the concepts had already been introduced elsewhere, it was revolutionary in that it was the first to combine them all in one camera. It was produced until October 1973 and was replaced by the quite similar Nikon F2. Aspects of its design remain in all of Nikon's subsequent SLR cameras, through the current Nikon F6 film and Nikon D5 digital models (which still share its Nikon F-mount for lenses). The "F" in Nikon F was selected by Nippon Kogaku from the letter F of the name of the designer of the bayonet mount, Mr. Fuketa. That tradition was carried all the way through their top line of Nikon cameras until the introduction of the Nikon D1 (digital) cameras decades later., Large format refers to any imaging format of 45inches (102127mm) or larger. Large format is larger than "medium format", the 66cm (22 inch) or 69cm (23 inch) size of Hasselblad, Rollei, Kowa, and Pentax cameras (using 120- and 220-rollfilm), and much larger than the 2436mm (~ 1.0x1.5inch) frame of 35mm format.
The main advantage of large format, film or digital, is higher resolution at the same pixel pitch, or same resolution with more larger pixels or grain. A 45inch image has about 16times the area, and thus 16 the total resolution, of a 35mm frame., 35mm film (millimeter) is the film gauge most commonly used for motion pictures and chemical still photography (see 135 film). The name of the gauge refers to the width of the photographic film, which consists of strips 34.980.03mm (1.3770.001inches) wide. The standard negative pulldown for movies ("single-frame" format) is four perforations per frame along both edges, which results in 16 frames per foot of film. For still photography, the standard frame has eight perforations on each side., A microscope (from the , "mikros", "small" and , "skopein", "to look" or "see") is an instrument used to see objects that are too small for the naked eye. The science of investigating small objects using such an instrument is called microscopy. Microscopic means invisible to the eye unless aided by a microscope., , formerly known as , is a Japanese multinational electronics corporation headquartered in Kadoma, Osaka, Japan., Nikonos Calypso is the name of a series of 35mm format cameras specifically designed for underwater photography launched by Nikon in 1963. The early Nikonos cameras were improvements of the Calypso camera, which was an original design by Jacques-Yves Cousteau and Belgian engineer Jean de Wouters, Binoculars or field glasses are binocular telescopes mounted side-by-side and aligned to point in the same direction, allowing the viewer to use both eyes (binocular vision) when viewing distant objects. Most are sized to be held using both hands, although sizes vary widely from opera glasses to large pedestal mounted military models., Sony Corporation is the electronics business unit and the parent company of the Sony Group, which is engaged in business through its four operating components electronics (video games, network services and medical business), motion pictures, music and financial services. These make Sony one of the most comprehensive entertainment companies in the world. Sony's principal business operations include Sony Corporation, Sony Pictures Entertainment, Sony Interactive Entertainment, Sony Music Entertainment, Sony Mobile (formerly Sony Ericsson) and Sony Financial. Sony is among the Semiconductor sales leaders by year and as of 2013, the fourth-largest television manufacturer in the world, after Samsung Electronics, LG Electronics and TCL., Its products include cameras, camera lenses, binoculars, microscopes, ophthalmic lenses, measurement instruments, rifle scopes, spotting scopes, and the steppers used in the photolithography steps of semiconductor fabrication, of which it is the world's second largest manufacturer. The companies held by Nikon form the Nikon Group. Among its products are Nikkor imaging lenses (for F-mount cameras, large format photography, photographic enlargers, and other applications), the Nikon F-series of 35 mm film SLR cameras, the Nikon D-series of digital SLR cameras, the Coolpix series of compact digital cameras, and the Nikonos series of underwater film cameras. Nikon's main competitors in camera and lens manufacturing include Canon, Sony, Fujifilm, Panasonic, Pentax, and Olympus., , better known as Fujifilm or simply Fuji, stylized as FUJiFILM, is a Japanese multinational photography and imaging company headquartered in Tokyo., Photolithography, also termed optical lithography or UV lithography, is a process used in microfabrication to pattern parts of a thin film or the bulk of a substrate. It uses light to transfer a geometric pattern from a photomask to a light-sensitive chemical "photoresist", or simply "resist," on the substrate. A series of chemical treatments then either engraves the exposure pattern into, or enables deposition of a new material in the desired pattern upon, the material underneath the photo resist. For example, in complex integrated circuits, a modern CMOS wafer will go through the photolithographic cycle up to 50 times., Nikkor is the brand of lenses produced by Nikon Corporation, including camera lenses for the Nikon F-mount., The 70 - 300mm lens is a telephoto zoom lens made by Nikon . The lens has an F - mount to work with all the SLRs line of cameras ( except the early 70 - 300G with the D40 ) . The lens comes in four different versions : AF f / 4 - 5.6G AF f / 4 - 5.6D AF f / 4 - 5.6D ED AF - S f / 4.5 - 5.6G IF - ED It is the successor of the 70 - 210 lens , which targets the prosumer market , one grade lower than 80 - 200mm with large aperture . Introduced in August 2006 , the current incarnation of the lens ( AF - S VR f / 4.5 - 5.6G IF - ED ) improves on the original with VR stabilization technology as well as with internally focusing components ( IF ) . More expensive than its partner 55 - 200mm lens , its construction is similar , with the exterior shell being fabricated from plastic components . It also shares a similarly stiff zoom ring with the 55 - 200mm , although a side benefit of this is that zoom creep is eliminated . Unlike the 55 - 200 , the 70 - 300mm lens is full - frame . Also , the longer barrel length allowed the focus ring to be relocated in front of the zoom ring , making manual focus operations simpler ., Measurement is the assignment of a number to a characteristic of an object or event, which can be compared with other objects or events. The scope and application of a measurement is dependent on the context and discipline. In the natural sciences and engineering, measurements do not apply to nominal properties of objects or events, which is consistent with the guidelines of the "International vocabulary of metrology" published by the International Bureau of Weights and Measures. However, in other fields such as statistics as well as the social and behavioral sciences, measurements can have multiple levels, which would include nominal, ordinal, interval, and ratio scales., Subject: nikon f 70-300mm lens, Relation: instance_of, Options: (A) application (B) april (C) area (D) brand (E) camera (F) camera lens (G) canon (H) chemical (I) company (J) complex (K) computer (L) corporation (M) day (N) device (O) eight (P) electronics (Q) event (R) field (S) film (T) format (U) four (V) instrument (W) letter (X) line (Y) lithography (Z) manufacturer ([) manufacturing (\) material (]) measurement (^) microscope (_) motion (') name (a) negative (b) network (c) object (d) october (e) operation (f) parent company (g) part (h) pattern (i) photography (j) point (k) process (l) revolutionary (m) rifle (n) series (o) side (p) single (q) size (r) statistics

question:
Context: Yoruba ("") is a language spoken in West Africa, mainly in Nigeria.
The number of speakers of Yoruba is approaching 30 million. It is a pluricentric language spoken principally in Benin and Nigeria, with communities in other parts of Africa, the Americas, and Europe. A variety of the language, Lucumi, is the liturgical language of the Santeria religion of the Caribbean. Many Yoruba words are used in the Afro-Brazilian religion known as Candomble. Yoruba is most closely related to the Itsekiri language (spoken in the Niger Delta) and to Igala (spoken in central Nigeria)., Obalokun was an Alaafin of Oyo , he was first in an era of successive despotic and short - lived kings of Oyo ., Yorubaland is the cultural region of the Yoruba people in West Africa. It spans the modern day countries of Nigeria, Togo and Benin, and covers a total land area of 142,114km or about the same size as the combined land areas of Greece and Montenegro, of which 106,016km, representing about 74.6% within Nigeria, 18.9% in Benin, and the remaining 6.5% in Togo. The geocultural space contains an estimated 55 million people, the overwhelming majority of them are ethnic Yorubas.
About 5.3 million people are estimated to practice Yoruba religion worldwide with the largest numbers found in Nigeria., Alaafin, or "Man of the Palace" in the Yoruba language, was the title of the emperor of the medieval Oyo empire of northwestern Yorubaland. It was retained through the fall of that state as the official title of the ceremonial ruler of the contemporary Oyo clan., The Oyo Empire was a Yoruba empire of what is today Western and North central Nigeria, and Eastern Benin. Established in the 15th century, the Oyo Empire grew to become one of the largest West African states. It rose through the outstanding organizational skills of the Yoruba, wealth gained from trade and its powerful cavalry. The Oyo Empire was the most politically important state in the region from the mid-17th to the late 18th century, holding sway not only over most of the other kingdoms in Yorubaland, but also over nearby African states, notably the Fon Kingdom of Dahomey in the modern Republic of Benin to the west., An emperor (through Old French "empereor" from ) is a monarch, usually the sovereign ruler of an empire or another type of imperial realm. Empress, the female equivalent, may indicate an emperor's wife ("empress consort"), mother ("empress dowager"), or a woman who rules in her own right ("empress regnant"). Emperors are generally recognized to be of a higher honour and rank than kings. In Europe the title of Emperor was, since the Middle Ages, considered equal or almost equal in dignity to that of Pope, due to the latter's position as visible head of the Church and spiritual leader of Western Europe. The Emperor of Japan is the only currently reigning monarch whose title is translated into English as "Emperor"., Subject: obalokun, Relation: country_of_citizenship, Options: (A) japan (B) montenegro (C) niger (D) nigeria (E) realm

question:
Context: The Muslim Arab army was under the command of Khalid ibn al - Walid and the battle took place at Anbar which is located approximately 80 miles from the ancient city of Babylon . Khalid besieged the Sassanian Persians in the city fortress , which had strong walls . Scores of Muslim archers were used in the siege . The Persian governor , Shirzad , eventually surrendered and was allowed to retire . The Battle of Al - Anbar is often remembered as the '' Action of the Eye '' since Muslim archers used in the battle were told to aim at the '' eyes '' of the Persian garrison ., Umar, also spelled Omar (born c.583 CEdied 3 November 644 CE), was one of the most powerful and influential Muslim caliphs in history. He was a senior Sahabi of the Islamic prophet Muhammad. He succeeded Abu Bakr (632634) as the second caliph of the Rashidun Caliphate on 23 August 634. He was an expert Islamic jurist known for his pious and just nature, which earned him the epithet Al-Farooq ("the one who distinguishes (between right and wrong)"). He is sometimes referred to as Umar I by historians of Islam, since a later Umayyad caliph, Umar II, also bore that name. , The Akkadian Empire was the first ancient Semitic-speaking empire of Mesopotamia, centered in the city of Akkad and its surrounding region, also called Akkad in ancient Mesopotamia and Accad in the Bible (Genesis 10:10). The empire united all the Akkadian and Sumerian speakers under one rule. The Akkadian Empire controlled Mesopotamia (modern Iraq, Kuwait, northeast Syria and southeast Turkey), the Levant (modern Syria and Lebanon), and eastern and southern parts of Anatolia (modern Turkey) and Iran, sending military expeditions as far south as Dilmun and Magan (modern Bahrain and Oman) in the Arabian Peninsula., Syria was an early Roman province, annexed to the Roman Republic in 64 BC by Pompey in the Third Mithridatic War, following the defeat of Armenian King Tigranes the Great. Following the partition of the Herodian Kingdom into tetrarchies in 6 AD, it was gradually absorbed into Roman provinces, with Roman Syria annexing Iturea and Trachonitis. Later, in 135 AD, in the aftermath of the Bar Kokhba revolt, Syrian province was merged with Judea province, creating the larger province of Syria Palaestina., Islam (' ;) is a religion articulated by the Quran, a text considered by its adherents to be the verbatim word of God ('), and, for the vast majority of adherents, the teachings and normative example (called the "sunnah", composed of accounts called "hadith") of Muhammad (5708 June 632 CE). It is the world's second-largest religion and the fastest-growing major religion in the world, with over 1.7 billion followers or 23% of the global population, known as Muslims. Islam is an Abrahamic monotheistic religion that upholds that God is one and incomparable and that the purpose of existence is to worship God. Muslims consider Muhammad to be the last prophet of God., The Ridda wars (Arabic: ), also known as the Wars of Apostasy, were a series of military campaigns launched by the Caliph Abu Bakr against rebel Arabian tribes during 632 and 633 AD, just after Muhammad died. The rebels' position was that they had submitted to Muhammad as the prophet of God, but owed nothing to Abu Bakr. Some rebels followed either Tulayha or Musaylima or Sajjah, all of whom claimed prophethood. Most of the tribes were defeated and reintegrated into the Caliphate. The peoples surrounding Mecca did not revolt., A head of state (or chief of state) is the public persona that officially represents the national unity and legitimacy of a sovereign state. In developing the current Constitution of France (1958), former French president Charles de Gaulle said the head of state should embody "the spirit of the nation" (""). In some countries, typically those with parliamentary governments, the head of state is a ceremonial figurehead that does not actually guide day-to-day government activities and may not even be empowered to exercise any kind of political authority (e.g., Queen Elizabeth II in the United Kingdom). In other countries, the head of state is also the head of government, such as in the U.S., where the president is both a public figurehead and the actual highest ranking political leader who, in practice, oversees the executive branch., Ab Bakr Abdallh bin Ab Qufah a-iddq (573 CE22 August 634 CE) popularly known as Abu Bakr, was a senior companion ("Sahabi") andthrough his daughter Aishathe father-in-law of the Islamic prophet Muhammad. Abu Bakr became the first openly declared Muslim outside Muhammad's family. Abu Bakr served as a trusted advisor to Muhammad. During Muhammad's lifetime, he was involved in several campaigns and treaties., Ab Sulaymn Khlid ibn al-Wald ibn al-Mughrah al-Makhzm (; 585642), also known as Sayf Allh al-Masll ("Drawn Sword of God"), was a companion of Muhammad. He is noted for his military tactics and prowess, commanding the forces of Medina under Muhammad and the forces of his immediate successors of the Rashidun Caliphate, Abu Bakr and Umar ibn Khattab. It was under his military leadership that Arabia, for the first time in history, was united under a single political entity, the Caliphate. Commanding the forces of the nascent Islamic state, Khalid was victorious in over a hundred battles, against the forces of the Byzantine-Roman Empire, Sassanid-Persian Empire, and their allies, in addition to other Arab tribes. His strategic achievements include the conquest of Arabia during the Ridda Wars, Persian Mesopotamia and Roman Syria within several years from 632 to 636. He is also remembered for his decisive victories at Yamamah, Ullais, and Firaz, and his tactical successes at Walaja and Yarmouk., A Muslim is someone who follows or practises Islam, a monotheistic Abrahamic religion. Muslims consider the Quran (Koran), their holy book, to be the verbatim word of God as revealed to the Islamic prophet and messenger Muhammad. They also follow the teachings and practices of Muhammad ("sunnah ") as recorded in traditional accounts ("hadith"). "Muslim" is an Arabic word meaning "one who submits (to God)"., Babylon (or ; Aramaic: , "Babel", , "Bavel", , "Bbil") was a major city of ancient Mesopotamia in the fertile plain between the Tigris and Euphrates rivers. The city was built upon the Euphrates and divided in equal parts along its left and right banks, with steep embankments to contain the river's seasonal floods. Babylon was originally a small Semitic Akkadian city dating from the period of the Akkadian Empire c. 2300 BC., The Rashidun Caliphate (') was the Islamic caliphate in the earliest period of Islam, comprising the first four caliphsthe "Rightly Guided" or Rashidun caliphs ('). It was founded after Muhammad's death in 632 (year 11 AH in the Islamic calendar). At its height, the Caliphate controlled an empire from the Arabian Peninsula and the Levant, to the Caucasus in the north, North Africa from Egypt to present-day Tunisia in the west, and the Iranian plateau to Central Asia in the east., Muhammad (c.570 CE 8 June 632 CE) is the central figure of Islam and widely regarded as its founder by non-Muslims. He is known as the "Holy Prophet" to Muslims, almost all of whom consider him to be the last prophet sent by God to mankind to restore Islam, believed by Muslims to be the unaltered original monotheistic faith of Adam, Abraham, Moses, Jesus, and other prophets. Muhammad united Arabia into a single Muslim polity and ensured that his teachings, practices, and the Quran, formed the basis of Islamic religious belief., A governor is, in most cases, a public official with the power to govern the executive branch of a non-sovereign or sub-national level of government, ranking under the head of state. In federations, "governor" may be the title of a politician who governs a constituent state and may be either appointed or elected. The power of the individual governor can vary dramatically between political systems, with some governors having only nominal and largely ceremonial power, while others having a complete control over the entire government., Subject: battle of al-anbar, Relation: point_in_time, Options: (A) 1 (B) 10 (C) 11 (D) 1958 (E) 2300 (F) 3 (G) 570 (H) 573 (I) 583 (J) 585 (K) 6 (L) 633 (M) 634 (N) 64 (O) 642 (P) 644
