Critical Reasoning — Implicit Assumptions Statement: I cannot contact you on phone from Karshik. Assumptions: I. Telephone facility is not available at Karshik. II. Nowadays it is difficult to contact on phone.

Introduction / Context:
The task is to identify what must be assumed for the speaker’s statement about phone contact from Karshik to make sense. The context is practical communication constraints tied to a location.

Given Data / Assumptions:

• Speaker says: “I cannot contact you on phone from Karshik.”
• Assumption I: There is no (or effectively unavailable) telephone facility at Karshik for the speaker.
• Assumption II: Generally, in modern times, contacting by phone is difficult.

Concept / Approach:
An implicit assumption is a necessary, local expectation behind the statement. The claim is place-specific (“from Karshik”), so any required assumption must also be localized, not a sweeping statement about phones “nowadays.”

Step-by-Step Solution:

Verification / Alternative check:
Negate I: “Telephone facility is available and working in Karshik for the speaker.” Then the statement “I cannot contact you from Karshik” loses its rationale unless a different reason is supplied. The assumption (lack/unavailability of facility) is therefore necessary. Negate II: Phone calls are generally easy. The original statement still holds because it is location-specific. Hence II is not required.

Why Other Options Are Wrong:

• Only II, Either, Neither, or Both: All overgeneralize or ignore the location-specific nature of the claim.

Common Pitfalls:
Assuming the speaker asserts absolute nonexistence of phones. The necessary assumption is simply that no usable facility is available to the speaker from Karshik at the time, which the option paraphrases as “not available at Karshik.”

Final Answer:
Only assumption I is implicit
