Final answer:
The correct question to ask with Fabric of the 6Fs is 'What is its function?', as it encompasses how the material use impacts the design and purpose of the fabric in economic terms.
Step-by-step explanation:
When examining fabric within the context of the 6Fs, which relates to the economic questions of production and consumption, the relevant question to ask is 'What is its function?' This question corresponds to considering how the material use affects the design of a product, signalling its purpose and the service it provides. By understanding the function, one can then derive conclusions on what the fabric is made of and how it is manufactured to suit its end use. For instance, understanding fabric involves looking at its pattern and texture, indicating its aesthetic or functional role in the textile industry. Similarly, by determining the function of the fabric, one can infer how important patterns are in textiles, as they can dictate the usage and appeal of the fabric in various applications.
