Statement: "Learn to solve Quantitative Aptitude questions in 3 seconds, plus Data Interpretation without written steps—taught by our experts—or get Rs 10,000 back as a penalty." — an advertisement by XYZ Coaching Institute. Assumptions: I. A candidate may not be able to read each question within three seconds. II. Solving Data Interpretation without any written work is hard for all aspirants.

Introduction / Context:This is a persuasive claim by a coaching institute offering dramatic performance gains (solving in “3 seconds”, DI with “no written steps”), sweetened by a money-back penalty. We must detect what the advertisement must assume, not what it merely suggests rhetorically.

Given Data / Assumptions:

• The institute promises speed and mental-work techniques.
• There is a Rs 10,000 penalty/guarantee mechanism.
• Assumption I: candidates cannot even read a question in 3 seconds.
• Assumption II: DI without written work is hard for all aspirants.

Concept / Approach:An ad typically assumes current difficulty exists for many students, so its service is valuable. But “many” is not “all”, and inability to read a question in 3 seconds is not required for the promise: they claim to teach scanning heuristics and patterns. The guarantee is a marketing device indicating confidence, not logical proof of I or II.

Step-by-Step Solution:1) If candidates can read quickly already, the course could still claim to improve solving speed. So I is not necessary.2) If some aspirants can do DI mentally already, the offer still stands for the rest; II’s universal “for all” is too strong.3) Therefore, neither I nor II is a necessary underpinning of the ad’s promise.

Verification / Alternative check:Guarantees often operate as signals; they do not define the logical minimum assumptions beyond “some students will benefit.” That weaker assumption is not among I or II.

Why Other Options Are Wrong:

• Only I / Only II / Both: Overstate the ad’s commitments.
• Either: At least one of I or II must be necessary; neither is.

Common Pitfalls:Reading superlative marketing literally as logical necessity; treat universals (“all”, strict time) with caution.

Final Answer:Neither I nor II is implicit.
