Multiple choice

Why did silk become a popular luxury fabric?

Directions: Read the following passage and answer the question that follows.

Though first reserved for Chinese royalty, silk spread gradually through the Chinese culture both geographically and socially. From there, silk garments began to reach regions throughout Asia. Silk rapidly became a popular luxury fabric in the many areas accessible to Chinese merchants, because of its texture and luster.
Demand for this exotic fabric eventually created the lucrative trade route now known as the Silk Road, taking silk westward and bringing gold, silver and wools to the East. It was named the Silk Road after its most valuable commodity – silk, considered even more precious than gold! Clearly, a basic understanding of silk history would not be complete without understanding the crucial role played by the Silk Road in its global trade and introduction to the world outside of China.
The Silk Road was some 4,000 miles long stretching from Eastern China to the Mediterranean Sea. A caravan tract, the Silk Road followed the Great Wall of China to the north-west, bypassing the Takla Makan desert, climbing the Pamir mountain range, crossing modern-day Afghanistan and going on to the Levant, with a major trading market in Damascus. From there, the merchandise was shipped across the Mediterranean sea. Few people travelled the entire route; goods were handled mostly by a series of middlemen.

  1. Because the Chinese royalty wore it

  2. Because it was very precious

  3. Because of its texture and luster

  4. Because it was an exotic fabric

  5. .
