Read the following passage carefully and select the most correct answers of the given questions: 

Though it may be essential to the imagination, traveling is necessary to an understanding of men. Only with long experience and the 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 traveling to those who wish to live at ease among their fellows.
