Paper craft

The governing concept is paper craft: origami creates forms by folding paper according to a planned sequence of creases. Traditional origami generally uses a single sheet and avoids cutting or gluing, although modern paper-folding practices may sometimes include variations. Birds, flowers, boxes, and geometric forms can all be produced through folds. Therefore, option A is correct. Shaping clay belongs to clay modelling, applying colours to a surface belongs to painting, and cutting or shaping stone belongs to stone carving. Those are different materials and techniques, so they are not the defining process of origami.

Direct answer: A, when paper is folded to create a form. Origami is a craft process in which a sheet of paper is deliberately folded into a recognizable or decorative object, such as a flower, bird, box, or geometric figure. The important clues are the material, paper, and the action, folding. Craft art involves controlling a material with skill to make something, so A describes origami precisely. B describes painting, where colour is applied to a surface to represent a scene. C describes music because rhythm and melody are performed through sound. D describes drama or theatre because spoken lines are acted on a stage. A useful memory cue is: origami equals paper plus folds; if the main process is painting, singing, or acting, it belongs to another art form.

The governing concept is the interaction of light with surface texture. A glossy surface has relatively aligned microscopic planes, so reflected light can form a concentrated, continuous highlight. A rough surface has many differently angled micro-surfaces; each reflects light in a different direction, breaking the highlight into smaller, irregular patches. Option A is correct. Roughness does not block all light, and glossy surfaces can produce strong highlights, so B and C are false.

Origami is the well-known traditional Japanese art of paper folding. Paper is folded to make birds, flowers, and other forms; traditional origami generally avoids cutting or gluing. Paper was invented in China, but origami is associated with Japan. Exam tip: Remember origami as the Japanese art of paper folding.

In paper quilling, thin paper strips are rolled, bent, and pressed into different shapes. These shapes are glued together to create flowers, leaves, and decorative patterns. Dissolving paper in water to make pulp relates to paper-making, not quilling. Exam tip: Remember that rolling strips into shapes is the key feature of quilling.

Origami is the traditional art of creating shapes such as birds, flowers, animals, and decorative objects by folding paper. The central technique is folding, usually without cutting, gluing, or adding other materials. Mosaic means arranging small pieces of glass, stone, or tile; collage means attaching materials to a surface; and calligraphy means decorative handwriting. Therefore, option A is correct.

Origami is the Japanese art of creating animals, flowers, objects, and other forms by folding paper, usually without cutting or pasting it. Mosaic is made by arranging small coloured pieces to form an image, so it is not paper-folding art. Exam tip: When you see “folding paper,” think of origami.
