Context: The 21st century is the current century of the "Anno Domini" era, (Latin for "in the year of Our Lord [Jesus Christ]") in accordance with the Gregorian calendar. It began on January 1, 2001 and will end on December 31, 2100. It is the first century of the 3rd millennium. It is distinct from the time span known as the 2000s, which began on January 1, 2000 and will end on December 31, 2099., Wheat ("Triticum" spp., most commonly "T. aestivum") is a cereal grain (botanically, a type of fruit called a caryopsis), originally from the Levant region but now cultivated worldwide. In 2016, world production of wheat was 749 million tonnes, making it the second most-produced cereal after maize (1.03 billion tonnes), with more than rice (499 million tonnes). Since 1960, world production of wheat and other grain crops has tripled and is expected to grow further through the middle of the 21st Century., Rice is the seed of the grass species "Oryza sativa" (Asian rice) or "Oryza glaberrima" (African rice). As a cereal grain, it is the most widely consumed staple food for a large part of the world's human population, especially in Asia. It is the agricultural commodity with the third-highest worldwide production, after sugarcane and maize, according to 2012 FAOSTAT data.
Since a large portion of maize crops are grown for purposes other than human consumption, rice is the most important grain with regard to human nutrition and caloric intake, providing more than one-fifth of the calories consumed worldwide by humans.
Wild rice, from which the crop was developed, may have its native range in Australia. Chinese legends attribute the domestication of rice to Shennong, the legendary emperor of China and inventor of Chinese agriculture. Genetic evidence has shown that rice originates from a single domestication 8,20013,500 years ago in the Pearl River valley region of Ancient China. Previously, archaeological evidence had suggested that rice was domesticated in the Yangtze River valley region in China., A cereal is any grass cultivated for the edible components of its grain (botanically, a type of fruit called a caryopsis), composed of the endosperm, germ, and bran. Cereal grains are grown in greater quantities and provide more food energy worldwide than any other type of crop and are therefore staple crops. Edible grains from other plant families, such as buckwheat (Polygonaceae), quinoa (Amaranthaceae) and chia (Lamiaceae), are referred to as pseudocereals., The Levant (Arabic:  "") is an approximate historical geographical term referring to a large area in the Eastern Mediterranean. In its widest historical sense, the Levant included all of the eastern Mediterranean with its islands, that is, it included all of the countries along the Eastern Mediterranean shores, extending from Greece to Cyrenaica. The term "Levant" entered English in the late 15th century from French. It derives from the Italian "Levante", meaning "rising", implying the rising of the sun in the east. As such, it is broadly equivalent to the Arabic term "Mashriq", meaning "the land where the sun rises"., Wheat is a color that resembles wheat . The first recorded use of wheat as a color name in English was in 1711 . Wheat is one of the X11 web colors ., The British tonne (British and SI; SI symbol: t), which is the same as the metric ton in the United States, is a non-SI metric unit of mass equal to 1,000 kilograms; or one megagram (Mg); it is equivalent to approximately pounds, or 0.984 long tons (imperial). Although not part of the SI "per se", the tonne is "accepted for use with" SI units and prefixes by the International Committee for Weights and Measures, along with several other units like the bar, litre and day., Maize (; "Zea mays" subsp. "mays", from after Taíno "mahiz"), also known as corn, is a large grain plant first domesticated by indigenous peoples in Mexico about 10,000 years ago. The six major types of corn are dent corn, flint corn, pod corn, popcorn, flour corn, and sweet corn., The ton is a unit of measure. It has a long history and has acquired a number of meanings and uses over the years. It is used principally as a unit of mass. Its original use as a measurement of volume has continued in the capacity of cargo ships and in terms such as the freight ton. It can also be used as a measure of energy, for truck classification, or as a colloquial term., Subject: wheat , Relation: named_after, Options: (A) 1 (B) 10 (C) 2001 (D) 2012 (E) asia (F) buckwheat (G) english (H) human (I) indigenous peoples (J) jesus christ (K) measurement (L) mexico (M) popcorn (N) sense (O) time (P) triticum
