Marco Polo.

Now that I have described the ships in which merchants voyage to and from India, let us change the subject and pass on to India itself. But first I will tell you of many islands that lie towards the east in this Ocean at which we have now arrived. We shall begin with an island that is called Japan.

Japan is an island far out at sea to the eastward, some 1,500 miles from the mainland. It is a very big island. The people are fair-complexioned, good-looking, and well-mannered. They are idolaters, wholly independent and exercising no authority over any nation but themselves.

Which sentence best reflects the author’s subjective perspective on the people of Japan?

The people of Japan live 1,500 miles from the mainland.
The people of Japan live on an island.
The people of Japan are good-looking and well-mannered.
The people of Japan exercise no authority over other nations.

The sentence "The people of Japan are good-looking and well-mannered." reflects the author's subjective perspective on the people of Japan.
