Input: Consider Input: Linseed oil, also known as flaxseed oil or flax oil, is a colourless to yellowish oil obtained from the dried, ripened seeds of the flax plant (Linum usitatissimum). The oil is obtained by pressing, sometimes followed by solvent extraction. Linseed oil is a drying oil, meaning it can polymerize into a solid form. Due to its polymer-forming properties, linseed oil can be used on its own or blended with combinations of other oils, resins or solvents as an impregnator, drying oil finish or varnish in wood finishing, as a pigment binder in oil paints, as a plasticizer and hardener in putty, and in the manufacture of linoleum. Linseed oil use has declined over the past several decades with increased availability of synthetic alkyd resins--which function similarly but resist yellowing.

Output: is flax oil the same as linseed oil?

Input: Consider Input: Drinking in public is legal in England and Wales -- one may carry a drink from a public house down the street (though it is preferred that the user requests a plastic glass to avoid danger of breakage and because the taking of the glass could be considered an offence of theft as only the drink has been purchased), and one may purchase alcohol at an off-licence and immediately begin drinking it outside. Separately, one may drink on aeroplanes and on most National Rail train services, either purchasing alcohol on-board or consuming one's own.
