Critical Reasoning — Implicit Assumptions Seller’s response: “The product X you asked for is not with us but can be made available against a firm order from you.” Assumptions to test: I. Product X is not in great demand. II. Product X is out of stock because a new model is coming up.

Introduction / Context:
The shop says it can source the item on a firm order though it is not currently available. We must decide whether lack of demand or an upcoming model must be assumed.

Given Data / Assumptions:

• Current stock: not available on shelf; can be procured on order.
• Assumption I: low demand.
• Assumption II: out of stock due to impending new model.

Concept / Approach:
There are many reasons a store does not stock an item routinely: supplier terms, storage limits, custom nature, cash-flow control, or lead-time logistics. None of these require assuming low demand or a model refresh.

Step-by-Step Solution:

Verification / Alternative check:
Negate I and II; the store could still stock on order due to policy or nature of product. Hence neither assumption is necessary.

Why Other Options Are Wrong:

• Any option including I or II inserts unjustified market inferences.

Common Pitfalls:
Assuming every non-stock item has low demand or is end-of-life. Procurement practices vary widely.

Final Answer:
Neither I nor II is implicit
