Question 15 is based on the passage you have just heard.

Passage Two

听力原文

       Hello, viewers. (12) Today I’m standing at a 2,000-year-old Roman era site. Here, the brightly colored scenes that once decorated a mansion are being dug up. These scenes are turning up in the southern French city of Arles, surprising the historians who have been working here since 2014. Patches of paint still cling to the stone walls of the bedroom and reception hall. 

      Some of these painted walls are preserved in places to a height of one meter. In addition, thousands of fragments that fell off the walls have been recovered. (13) These pieces have been put back together with great care and display a variety of images. Some of these images include figures never seen before in France, such as a woman playing a stringed instrument, possibly a character from mythology. (14) The paintings were done with such skill and with such expensive dyes that experts believed the artists originally came from Italy. They were likely hired by one of the city’s elite.

       (15) Perhaps a Roman official wanted Pompeii-like interior to remind him of home. He was probably stationed in this provincial trading port founded in 46 B.C. as a colony for veterans of the Roman army. Or maybe a wealthy local wanted to show off his worldly sophistication. The paintings may yield even more stunning surprises as additional sections are put together like pieces of a puzzle. Whoever it was that created such magnificent pieces of art, they surely had no idea that their work would still be around thousands of years later.

15. What do we learn from the passage about the owner of the mansion?

解析：C。录音中对公馆的主人进行了一系列猜测，他或许是罗马官员，也可能是当地富人，可见公馆主人的身份尚未确定，故C选项为正确答案。
