Statement — “For locating buyers, negotiating with importers, securing buying agencies and orders, and exporting your goods, write to us.”\nConclusions:\nI. The advertiser is an export house.\nII. All dealings of the advertiser are carried out only through correspondence.

Introduction / Context:
An advertisement claims capability across the export cycle, inviting readers to “write to us.” From this, we test which conclusions are logically supported.

Given Data / Assumptions:

• The advertiser facilitates export-related activities end-to-end.
• The call to action is to write to them.

Concept / Approach:
Providing buyer location, importer negotiation, agency securing, and export handling strongly suggests the entity functions as an export house or export service organization—supporting I. However, the instruction “write to us” is a contact method, not proof that all dealings occur only via correspondence; therefore II is overbroad.

Step-by-Step Solution:
1) Map service set → export house role.2) Communication channel ≠ exclusivity of medium → reject II.

Why Other Options Are Wrong:
Only II/Either/Both: infer exclusivity of correspondence without textual basis. Neither: ignores the clear export-house implication.

Common Pitfalls:
Confusing an invitation to contact with a restriction on all future dealings.

Final Answer:
Only conclusion I follows.
