Read the passage carefully and answer the question based on the passage:
Advertisements draw our attention to various products and describe them positively so that we become interested in buying them. Have you ever heard of the word brand? Advertising is all about building brands. At a very basic level, branding means stamping a product with a particular name or sign. This is done in order to differentiate it from other products in the market.
Just naming the product may not make us buy it. This is where advertising comes in. It plays a crucial role in trying to convince us to buy the product that is advertised by claiming certain special values of a brand. These special values of a brand are called brand values. These brand values are conveyed through the use of visuals and words to give us an overall image that appeals to us.
Advertisements are an important part of our social and cultural life today. We watch advertisements, discuss them and often judge people according to the brand products they use. Given that advertisements are such a powerful source of influence of our lives, we need to be able to understand the ways in which they work.
