Task: Question Answering
Input (English): Context: The Alps are the highest and most extensive mountain range system that lies entirely in Europe, stretching approximately across eight Alpine countries: Austria, France, Germany, Italy, Liechtenstein, Monaco, Slovenia, and Switzerland. The mountains were formed over tens of millions of years as the African and Eurasian tectonic plates collided. Extreme shortening caused by the event resulted in marine sedimentary rocks rising by thrusting and folding into high mountain peaks such as Mont Blanc and the Matterhorn. Mont Blanc spans the FrenchItalian border, and at is the highest mountain in the Alps. The Alpine region area contains about a hundred peaks higher than 4000 metres (just over 13,000 feet)., In topography, prominence characterizes the height of a mountain or hill's summit by the vertical distance between it and the lowest contour line encircling it but containing no higher summit within it. It is a measure of the independence of a summit. A peak's "key col" is a unique point on this contour line and the parent peak is some higher mountain, selected according to various objective criteria. , A Mont Blanc ( or Mont - Blanc aux marrons ) is a dessert of puréed , sweetened chestnuts topped with whipped cream . The name comes from Mont Blanc , as it resembles a snow - capped mountain ., The chestnut group is a genus (Castanea) of eight or nine species of deciduous trees and shrubs in the beech family Fagaceae, native to temperate regions of the Northern Hemisphere., Mont Blanc or Monte Bianco, both meaning "White Mountain", is the highest mountain in the Alps and the highest in Europe after the Caucasus peaks. 
It rises above sea level and is ranked 11th in the world in topographic prominence., Vanilla is a flavoring derived from orchids of the genus "Vanilla", primarily from the Mexican species, flat-leaved vanilla ("V. planifolia"). The word "vanilla", derived from the diminutive of the Spanish word ("vaina" itself meaning sheath or pod), is translated simply as "little pod". Pre-Columbian Mesoamerican people cultivated the vine of the vanilla orchid, called "tlilxochitl" by the Aztecs. Spanish conquistador Hernán Cortés is credited with introducing both vanilla and chocolate to Europe in the 1520s., Europe is a continent that comprises the westernmost part of Eurasia. Europe is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, and the Mediterranean Sea to the south. To the east and southeast, Europe is generally considered as separated from Asia by the watershed divides of the Ural and Caucasus Mountains, the Ural River, the Caspian and Black Seas, and the waterways of the Turkish Straits. Yet the non-oceanic borders of Europea concept dating back to classical antiquityare arbitrary. The primarily physiographic term "continent" as applied to Europe also incorporates cultural and political elements whose discontinuities are not always reflected by the continent's current overland boundaries., Cream is a dairy product composed of the higher-butterfat layer skimmed from the top of milk before homogenization. In un-homogenized milk, the fat, which is less dense, will eventually rise to the top. In the industrial production of cream, this process is accelerated by using centrifuges called "separators". In many countries, cream is sold in several grades depending on the total butterfat content. Cream can be dried to a powder for shipment to distant markets. Cream has high levels of saturated fat., A mountain is a large landform that stretches above the surrounding land in a limited area, usually in the form of a peak. A mountain is generally steeper than a hill. Mountains are formed through tectonic forces or volcanism. These forces can locally raise the surface of the earth. Mountains erode slowly through the action of rivers, weather conditions, and glaciers. A few mountains are isolated summits, but most occur in huge mountain ranges., Whipped cream is cream that is whipped by a whisk or mixer until it is light and fluffy. Whipped cream is often sweetened and sometimes flavored with vanilla. Whipped cream is often called Chantilly cream or crème Chantilly., Subject: mont blanc , Relation: has_part, Options: (A) a (B) arctic ocean (C) asia (D) austria (E) black (F) castanea (G) chocolate (H) cream (I) earth (J) eurasia (K) europe (L) flat (M) france (N) germany (O) italy (P) key (Q) mont (R) part (S) product (T) s (U) spanish (V) switzerland (W) system (X) vanilla (Y) whipped cream (Z) word
