A more thorough explanation:

A strong mark is a type of trademark that is considered to be distinctive and memorable. It is easily recognizable and can help to distinguish a company's products or services from those of its competitors.

• Apple's logo is a strong mark because it is simple, unique, and easily recognizable.
• Coca-Cola's name and distinctive script font are also strong marks because they are well-known and associated with the company's products.

These examples illustrate how a strong mark can help to build brand recognition and loyalty. When consumers see a strong mark, they are more likely to remember the company and its products, which can lead to increased sales and revenue.
