premise: Fast-moving consumer goods (FMCG) or consumer packaged goods (CPG) are products that are sold quickly and at relatively low cost. Examples include non-durable goods such as packaged foods, beverages, toiletries, over-the-counter drugs and many other consumables. In contrast, durable goods or major appliances such as kitchen appliances are generally replaced over a period of several years.
hypothesis: Durable items get changed every so often
reason: The scenario stated that durable items were changed every few years. I played off that to put 'every so often'. I believe I confused it as it was mostly unsure whether that was true or not. That is, it probably wasn't sure if 'every few years' and 'every so often' could mean the same thing
