Statement: "This drink can be had either as it is, or after adding ice to it." - An advertisement. Assumptions: People differ in their preferences. Some people will get attracted to the drink as it can be had as it is.

Given data

• Ad: The drink can be had either as it is, or after adding ice.
• Assumption I: People differ in their preferences.
• Assumption II: Some people will be attracted because it can be had as it is.

Concept/Approach

Offering alternative modes targets varied tastes; it does not commit to which specific mode will attract customers.

Step-by-step reasoningGiving two options presumes preference heterogeneity ⇒ I.No specific claim that 'as it is' (vs with ice) will attract people ⇒ II not necessary.

Verification/Alternative

The ad would still make sense even if the attraction came mainly from the 'with ice' option.

Common pitfalls

• Assuming a particular option is the draw when the ad merely broadens appeal.

Final AnswerOnly assumption I is implicit.
