Final answer:
Companies in the pharmaceutical industry are expected to spend significant amounts on R&D due to the high costs and risks associated with developing new drugs. Unlike other industries, pharmaceutical firms face long development times and rely on patents for temporary market advantage.
Step-by-step explanation:
In the context of significant research and development (R&D) expenditures, it would be expected that companies in the pharmaceutical industry would allocate considerable resources to R&D activities. The development of new drugs is a costly and time-consuming process, with each R&D project carrying the risk of failure. On average, it takes over a decade and can cost approximately $800 million to bring a new drug to market.
Contrastingly, industries such as clothes retailers, groceries, and wholesale distributors of computer parts typically do not undergo as extensive R&D processes. These sectors may focus more on supply chain efficiency, customer service, and market positioning rather than on the innovation of new technologies and products to the same degree as pharmaceutical companies.
