Critical Interpretation of Advertisements: The advertisement says, “Use ‘Kraft’ colours. They add colour to our life.” Determine which conclusions, if any, logically follow: (I) Catchy slogans do not attract people; (II) People prefer dark colours.

Given data

• Premise: An advertising slogan praising a product (“Kraft” colours).
• Conclusion I: Catchy slogans fail to attract.
• Conclusion II: People like dark colours.

Concept/Approach
Ads are persuasive claims; they do not, by themselves, establish general truths about consumer response or color preferences without supporting data.

Step-by-step evaluation
• The ad’s existence cannot prove that slogans do not attract customers; indeed it presumes the opposite. I does not follow.• The ad never mentions 'dark' colors or any preference survey. II also does not follow.

Final Answer
Neither I nor II follows.
