Task: Question Answering
Input (English): Context: Ink is a liquid or paste that contains pigments or dyes and is used to color a surface to produce an image, text, or design. Ink is used for drawing or writing with a pen, brush, or quill. Thicker inks, in paste form, are used extensively in letterpress and lithographic printing., An inkstone ( simplified Chinese :  ; traditional Chinese :  ; pinyin : yàn ) ( simplified Chinese :  ; traditional Chinese :  ; pinyin : yàn tái ) ( Japanese :  suzuri ) ( Korean :  byoru ) is a stone mortar for the grinding and containment of ink . In addition to stone , inkstones are also manufactured from clay , bronze , iron , and porcelain . The device evolved from a rubbing tool used for rubbing dyes dating around 6000 to 7000 years ago ., A brush is a tool with bristles, wire or other filaments, used for cleaning, grooming hair, make up, painting, surface finishing and for many other purposes. It is one of the most basic and versatile tools known to mankind, and the average household may contain several dozen varieties. It generally consists of a handle or block to which filaments are affixed either parallel- or perpendicular-wise, depending on the way the brush is to be gripped during use. The material of both the block and bristles or filaments is chosen to withstand hazards of its application, such as corrosive chemicals, heat or abrasion., A dye is a colored substance that has an affinity to the substrate to which it is being applied. The dye is generally applied in an aqueous solution, and may require a mordant to improve the fastness of the dye on the fiber., A pen (Latin: "penna", feather) is a writing implement used to apply ink to a surface, such as paper, for writing or drawing. Historically, reed pens, quill pens, and dip pens were used, with a nib dipped in ink. Ruling pens allow precise adjustment of line width, and still find a few specialized uses, but technical pens such as the Rapidograph are more commonly used. Modern types also include ballpoint, rollerball, fountain, and felt or ceramic tip pens., Printing is a process for reproducing text and images using a master form or template. The earliest examples include Cylinder seals and other objects such as the Cyrus Cylinder and the Cylinders of Nabonidus. The earliest known form of woodblock printing came from China dating to before 220 A.D. Later developments in printing include the movable type, first developed by Bi Sheng in China. Johannes Gutenberg introduced mechanical movable type printing to Europe in the 15th century. His printing press played a key role in the development of the Renaissance, Reformation, the Age of Enlightenment, and the scientific revolution and laid the material basis for the modern knowledge-based economy and the spread of learning to the masses., A liquid is a nearly incompressible fluid that conforms to the shape of its container but retains a (nearly) constant volume independent of pressure. As such, it is one of the four fundamental states of matter (the others being solid, gas, and plasma), and is the only state with a definite volume but no fixed shape. A liquid is made up of tiny vibrating particles of matter, such as atoms, held together by intermolecular bonds. Water is, by far, the most common liquid on Earth. Like a gas, a liquid is able to flow and take the shape of a container. Most liquids resist compression, although others can be compressed. Unlike a gas, a liquid does not disperse to fill every space of a container, and maintains a fairly constant density. A distinctive property of the liquid state is surface tension, leading to wetting phenomena., IMAGE (from Imager for Magnetopause-to-Aurora Global Exploration), or Explorer 78, was a NASA MIDEX mission that studied the global response of the Earth's magnetosphere to changes in the solar wind. It was launched March 25, 2000 by a Delta II rocket from Vandenberg AFB and ceased operations in December 2005., A quill pen is a writing implement made from a moulted flight feather (preferably a primary wing-feather) of a large bird. Quills were used for writing with ink before the invention of the dip pen, the metal-nibbed pen, the fountain pen, and, eventually, the ballpoint pen. The hand-cut goose quill is rarely used as a calligraphy tool, because many papers are now derived from wood pulp and wear down the quill very quickly. However, it is still the tool of choice for a few professionals and provides an unmatched sharp stroke as well as greater flexibility than a steel pen. , Design is the creation of a plan or convention for the construction of an object, system or measurable human interaction (as in architectural blueprints, engineering drawings, business processes, circuit diagrams, and sewing patterns). Design has different connotations in different fields (see design disciplines below). In some cases, the direct construction of an object (as in pottery, engineering, management, coding, and graphic design) is also considered to be design., A pigment is a material that changes the color of reflected or transmitted light as the result of wavelength-selective absorption. This physical process differs from fluorescence, phosphorescence, and other forms of luminescence, in which a material emits light., Drawing is a form of visual art in which a person uses various drawing instruments to mark paper or another two-dimensional medium. Instruments include graphite pencils, pen and ink, inked brushes, wax color pencils, crayons, charcoal, chalk, pastels, various kinds of erasers, markers, styluses, various metals (such as silverpoint) and electronic drawing., Subject: inkstone, Relation: instance_of, Options: (A) 25 (B) color (C) constant (D) construction (E) convention (F) design (G) drawing (H) dye (I) economy (J) exploration (K) fiber (L) four (M) gas (N) human (O) ink (P) key (Q) liquid (R) magnetosphere (S) material (T) matter (U) may (V) mission (W) object (X) painting (Y) paper (Z) pen ([) person (\) pigment (]) process (^) property (_) rocket (`) shape (a) solution (b) state (c) steel (d) surface (e) system (f) tool (g) wind (h) wing (i) wire (j) writing implement
