paragraph 1,We begin more than 2,000 years ago. In a city on the edge of the Mediterranean Sea, there lived a Greek explorer named Pytheas. Almost nothing is known of him. Historians cannot say precisely when he lived, what he looked like, or whether he was rich or poor, and they don't even know exactly where he went. All they can say for certain is that he made a remarkable voyage north to a place where he thought the sea looked like curdled milk, and that when he returned home, he wrote about it in a book called ,begin italics,On the Ocean,end italics,.

paragraph 2,Sadly, all copies of Pytheas's account have disappeared. It obviously caused a stir in the classical world, though, because in works that ,begin italics,do,end italics, survive, at least eighteen other writers mention it. One of them, the Greek geographer Strabo, described Pytheas as a fraud and "the worst possible liar." Others believed he was telling the truth—and today most historians agree, which is why he is often called the first great explorer.

paragraph 3,Pytheas's hometown was Massilia, the southern French port we now call Marseilles. Like many other cities around the Mediterranean, it had been founded by Greeks who had left their homeland to better themselves. Their settlements flourished, and by Pytheas's lifetime, in the fourth century BC, Greek civilization was the envy of the Western world. So although Pytheas was not born in Greece, he would have spoken, written, and thought like a Greek—and been proud to do so.Based on the passage, what is a ,begin emphasis,gnomon,end emphasis,?

Answer: 4. a device for measuring time and location.

Reason: A gnomon is the part of a sundial (a staff or projection) that casts a shadow used to tell time and determine latitude, so it’s a measuring device rather than simply a shadow or a length unit.
