Question: What continent can both Fraxinus and Rice be found?

Context paragraphs:
Rice: 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 (rice, 741.5 million tonnes in 2014), after sugarcane (1.9 billion tonnes) and maize (1.0 billion tonnes).

Hirschmanniella oryzae: Hirschmanniella oryzae, i.e. rice root nematode (RRN), is among the major pests of rice and is the most common plant-parasitic nematode found on irrigated rice.  Recent modifications in cultivation practices have led to a substantial increase in rice production, which has been accompanied by heightened levels of RRN.  The proportional increases in RRN with rice production can be explained by the nematode's impeccable adaptation towards constantly flooded conditions in which irrigated rice is often being grown.

Weedy rice: Weedy rice, also known as red rice, is a variety of rice ("Oryza") that produces far fewer grains per plant than cultivated rice and is therefore considered a pest.  The name "weedy rice" is used for all types and variations of rice which show some characteristic features of cultivated rice and grow as weeds in commercial rice fields.  Populations of weedy rice are found in many rice-growing regions.  Weedy rice varieties generally have fragile stalks that self-seed before harvest.  Variations of weedy rice adapt to a wide range of natural conditions.

Climate of Africa: Due to Africa's position across equatorial and subtropical latitudes in both the northern and southern hemisphere, several different climate types can be found on the continent of Africa.  Africa mainly lies within the intertropical zone between the Tropic of Cancer and the Tropic of Capricorn.  Only the northernmost and the southernmost fringes of the continent have a Mediterranean climate.  Because of this geographical situation, Africa is a hot continent as the solar radiation intensity is always high.  Thus, warm and hot climates prevails all over Africa but the northern part is the most marked part by aridity and high temperatures.  The climate of Africa is a range of climates such as the equatorial climate, the tropical wet and dry climate, the tropical monsoon climate, the semi-desert climate (semi-arid), the desert climate (hyper-arid and arid), the subtropical highland climate etc.  Temperate climates remain rare through the continent except at very high elevations and along the fringes.  In fact, the climate of Africa is more dependent to rainfall amount than to temperatures as they are consistently high.  African deserts are the sunniest and the driest parts of the continent due to the prevailing presence of the subtropical ridge with subsiding, hot, dry air masses.  Africa holds many heat-related records : the continent has the hottest extended region year-round, the areas with the hottest summer climate, the highest sunshine duration etc.

Ulmus minor 'Boissieri': The Field Elm cultivar Ulmus minor 'Boissieri' , (Persian: نارون برگ‌ریز or نارون گل‌پشه‌ای‎ ‎ ), found in Iran and identified by Irina Grudzinskaya as the species "U. boissieri" in 1977.  The tree is endemic to the Zagros forests, with "Quercus brantii, Celtis australis, Platanus orientalis, Fraxinus" sp., and "Cerasus mehaleb".  The tree is also found in the provinces of Kermanshah (Qasr-e Shirin, Bisotun) and Kerman.

Rice barn: A rice barn is a type of barn used worldwide for the storage and drying of harvested rice.  The designs, usually specialized to its function, and it may vary between countries or between provinces.  Rice barns in Asia appear quite different from rice barns found in other parts of the rice cultivating world.  In the United States rice barns were once common throughout the state of South Carolina.

Fraxinus: Fraxinus , English name ash, is a genus of flowering plants in the olive and lilac family, Oleaceae.  It contains 45–65 species of usually medium to large trees, mostly deciduous though a few subtropical species are evergreen.  The genus is widespread across much of Europe, Asia and North America.

Genmaicha: Genmaicha (玄米茶 , "brown rice tea") , also called brown rice green tea, is the Japanese name for green tea combined with roasted brown rice.  It is sometimes referred to colloquially as "popcorn tea" because a few grains of the rice pop during the roasting process and resemble popcorn.  Although today it is consumed by all segments of society, this type of tea was originally drunk by poor Japanese, as the rice served as a filler and reduced the price of the tea; which is why it is also known as the "people's tea".  It was also used by those persons fasting for religious purposes or who found themselves to be between meals for long periods of time.  The sugar and starch from the rice cause the tea to have a warm, full flavor that is similar to that of nuts.  It is considered easy to drink and helps one's stomach feel better.

Black rice: Black rice (also known as purple rice) is a range of rice types of the species "Oryza sativa" L., some of which are glutinous rice.  Varieties include Indonesian black rice and Thai jasmine black rice.  Black rice is known as "chak-hao" in Manipur, an Indian state on the eastern border with Myanmar, where desserts made from black rice are served at major feasts.  Black rice is a source of iron, vitamin E, and antioxidants (more than in blueberries).  The bran hull (outermost layer) of black rice contains one of the highest levels of anthocyanins found in food.  The grain has a similar amount of fiber to brown rice and, like brown rice, has a mild, nutty taste.

Fraxinus americana: Fraxinus americana, the white ash or American ash, is a species of "ash tree" native to eastern and central North America.  It is found in mesophytic hardwood forests from Nova Scotia west to Minnesota, south to northern Florida, and southwest to eastern Texas.  Isolated populations have also been found in western Texas, Wyoming and Colorado, and the species is reportedly naturalized in Hawaii.
