Final answer:
If you're uncertain about the qualities of what you're selling, it may lead to failure when selling cars, food, or home electronics.
Step-by-step explanation:
If you're going to sell cars, food, or home electronics, you're more likely to fail if you're less than 100% certain about the qualities of what you are buying or selling.
When information about the quality of products is highly imperfect, it may be difficult for a market to exist. For example, if a car dealer cannot provide accurate information about the condition or history of a used car, potential buyers may hesitate to make a purchase.
Similarly, if a food seller does not have proper quality control measures in place or cannot assure customers of the freshness and safety of their products, customers may be reluctant to buy. The same goes for home electronics - if the seller cannot provide detailed specifications or warranties, customers may be more likely to choose a different seller.
