Passage: It now became relevant to define the east of the eastern question. In about the middle of the 19th century "Near East" came into use to describe that part of the east closest to Europe. The term "Far East" appeared contemporaneously meaning Japan, China, Korea, Indonesia and Viet Nam; in short, the East Indies. "Near East" applied to what had been mainly known as the Levant, which was in the jurisdiction of the Ottoman Porte, or government. Those who used the term had little choice about its meaning. They could not set foot on most of the shores of the southern and central Mediterranean from the Gulf of Sidra to Albania without permits from the Ottoman Empire. Question: When did "Near East" come into use to describe the part of the east closest to Europe?

Ex Output:
middle of the 19th century

Passage: The term alloy is used to describe a mixture of atoms in which the primary constituent is a metal. The primary metal is called the base, the matrix, or the solvent. The secondary constituents are often called solutes. If there is a mixture of only two types of atoms, not counting impurities, such as a copper-nickel alloy, then it is called a binary alloy. If there are three types of atoms forming the mixture, such as iron, nickel and chromium, then it is called a ternary alloy. An alloy with four constituents is a quaternary alloy, while a five-part alloy is termed a quinary alloy. Because the percentage of each constituent can be varied, with any mixture the entire range of possible variations is called a system. In this respect, all of the various forms of an alloy containing only two constituents, like iron and carbon, is called a binary system, while all of the alloy combinations possible with a ternary alloy, such as alloys of iron, carbon and chromium, is called a ternary system. Question: A five-part alloy is known as?

Ex Output:
ternary alloy

Passage:  In 1955, DC Sinclair and G Weddell developed peripheral pattern theory, based on a 1934 suggestion by John Paul Nafe. They proposed that all skin fiber endings (with the exception of those innervating hair cells) are identical, and that pain is produced by intense stimulation of these fibers. Another 20th-century theory was gate control theory, introduced by Ronald Melzack and Patrick Wall in the 1965 Science article "Pain Mechanisms: A New Theory". The authors proposed that both thin (pain) and large diameter (touch, pressure, vibration) nerve fibers carry information from the site of injury to two destinations in the dorsal horn of the spinal cord, and that the more large fiber activity relative to thin fiber activity at the inhibitory cell, the less pain is felt. Both peripheral pattern theory and gate control theory have been superseded by more modern theories of pain[citation needed]. Question: What year was peripheral pattern theory developed? 

Ex Output:

1955
