A.I. Explanation:

Option 1: "To propagate."

Explanation: The term 'propagate' generally means to spread or promote an idea or information. However, the text does not mention this as a function of advertising. Instead, it emphasizes that advertising serves to inform consumers about products, which is a more specific and relevant function.

Option 2: "To increase people’s reading ability."

Explanation: While reading advertisements may contribute to improving reading skills, the text does not support this as a purpose of advertising. The main focus is on how advertisements provide information about products, making this option irrelevant to the question.

Option 3: "To give information."

Explanation: The text explicitly states that one important function of advertising is to inform consumers about household goods. This aligns perfectly with the question, as it highlights that advertising is not solely for selling but also for educating the public about products.

Option 4: "To make more money for advertiser."

Explanation: This option suggests that the primary purpose of advertising is to generate profit for advertisers. While this may be a consequence of effective advertising, the text emphasizes that the role of advertising extends beyond profit-making to include informing consumers, making this option too narrow and not aligned with the text's main idea.
