问题如下：
A flower shop has preferred supplier arrangements with an answering service, to take orders after hours, and a bicycle delivery service, to ensure that it can make deliveries quickly, reliably, and at a reasonable cost. Which of the following statements is most accurate for the flower shop?
(备注：原版书课后题原题。和真题的出题形式不同（真题只有三个选项）。大家做题时不用纠结题目形式，关注知识点原理即可)
选项：
A.The answering service is part of its supply chain.
B.The bicycle delivery service is part of its value chain.
C.The bicycle delivery service is part of its supply chain.
D.The bicycle delivery service is not a part of the value proposition for the flower shop.
解释：
SolutionC is correct. A supply chain includes all the steps involved in producing and delivering a physical product to the end customer, regardless of whether those steps are performed by a single firm. A value chain includes only those functions performed by a single firm, but it also includes functions that are valuable to customers but may not involve physical transformation or handling of the product. The bicycle delivery service is a source of value to customers, so it is part of the flower shop's value proposition, but it is performed by a third party, so it is not part of the flower shop value chain but, rather, is part of its supply chain. The answering service is not a step in the physical goods flow, so it is not a part of the supply chain.
