Step-by-step explanation:
Training in selling techniques does not reduce product knowledge; rather, it is designed to increase a salesperson's expertise about the products they are selling. Therefore, the correct answer to the question “Providing training in selling techniques helps a salesperson in all of the following ways except” is Reducing Product Knowledge.
Good training in selling techniques typically helps salespeople by enhancing communication skills, which can be used in various professional situations such as applying for jobs, making presentations, interacting with customers, and asking for a raise. Additionally, it helps in building customer relationships, as it teaches salespeople how to interpret behavior and reassure customers who might have concerns due to imperfect information. Lastly, such training is essential in improving closing techniques which are pivotal in finalizing sales. These elements underscore the necessity of continual learning and skill refinement.
