Critical reasoning — identify implicit assumptions Statement: “I want to present a book on techniques of yoga to Ajay on his birthday.” — A tells B. Assumptions to evaluate: I. A will be invited by Ajay to the birthday celebration. II. Ajay is not keeping good health (hence yoga techniques are needed). III. A book is an acceptable birthday gift.

Introduction / Context:This is a practical assumption question about gifting. A says he wants to gift Ajay a yoga techniques book for his birthday. We must determine which assumptions are required for this statement of intent to be reasonable.

Given Data / Assumptions:

• A intends to give Ajay a yoga book as a birthday gift.
• I: A will be invited to the party.
• II: Ajay's health is poor, so he needs yoga.
• III: Books are acceptable birthday gifts.

Concept / Approach:For an intention to present a gift, it is not necessary that the giver be formally invited to a party; gifts can be given before, after, or in absence of a party. Likewise, yoga books can be gifted for interest or self-improvement without assuming poor health. However, it is necessary that a book be a socially acceptable gift category; otherwise the intention would be odd.

Step-by-Step Solution:

Verification / Alternative check:Gifts are routinely exchanged outside of parties, and hobby/interest books are common—making III the minimal assumption.

Why Other Options Are Wrong:

• Only II / Only I and III / All / None: Either add unneeded conditions or erase the necessary acceptability assumption.

Common Pitfalls:Assuming a gift implies diagnosis or an invitation; confusing a suitable category with a specific motive.

Final Answer:Only III is implicit
