Only with long experience and opening of his wares on many a beach where his language is not spoken, will the merchant come to know the worth of what he carries, and what is parochial and what is universal in his choice. Such delicate goods as justice, love and honour, courtesy, and indeed all the things we care for, are valid everywhere but they are variously moulded and often differently handled, and sometimes nearly unrecognizable if you meet them in a foreign land, and the art of learning fundamental common values is perhaps the greatest gain of travel to those who wish to live at ease among their fellows.

Correct Option (4)

All three assumptions are valid based on the provided passage.

• Assumption 1: Travel leads to an understanding of humans. The passage illustrates how a merchant, through extensive travel and interaction in diverse cultural contexts, discerns the universal from the parochial in his offerings and values. This process inherently involves gaining insight into human nature, cultural variations, and shared principles, thereby fostering an understanding of humanity.
• Assumption 2: Travel helps those who wish to learn fundamental common values. The passage explicitly states, "the art of learning fundamental common values is perhaps the greatest gain of travel to those who wish to live at ease among their fellows." This directly supports the assumption.
• Assumption 3: A person with long experience in travel can resolve differences amongst people. The passage describes how long experience in travel reveals that values like justice, love, and honour are "valid everywhere but they are variously moulded and often differently handled." An individual who comprehends both the universality and the diverse manifestations of these values, as gained through extensive travel, is better equipped to identify commonalities and bridge differences, thus potentially aiding in conflict resolution.

Incorrect Options:

• Option 1 (1 and 2 only): This option is incorrect because Assumption 3 is also a valid inference from the passage, as explained above.
• Option 2 (2 and 3 only): This option is incorrect because Assumption 1 is also a valid inference from the passage, as explained above.
• Option 3 (1 and 3 only): This option is incorrect because Assumption 2 is explicitly stated in the passage as a significant benefit of travel.
