Paper 1
Revise: Primary material sourcesA factory rarely starts with a tree, a lump of ore or crude oil. These primary sources must first be processed into materials that manufacturers can work with. The resulting stock forms include timber planks, metal sheets, polymer granules and rolls of fabric.
Link each material to its original source, then describe the conversion stages in order. A stock form such as a sheet is not a primary source.
