Tatami rooms are often seen in pictures of Japan, but are they still commonly used today or are they merely quaint throwbacks to an earlier time?

Please select the statement that is most accurate.

	Although thick, woven straw tatami mats were used for centuries and are still found in some older homes, tatami has largely been replaced by more durable, permanent flooring in today's Japanese homes.
	Tatami mats are still widely used in Japan. They are so standard, they are even used as a unit of measure for Japanese rooms and apartments (a room with floor space for six mats is called a "six-mat room").
	Although still used commonly, the modern tatami is quite different from its ancestor. It is much thinner, making it easy to roll up and store away when not in use, allowing rooms in small Japanese houses to be more versatile.

The correct answer is B.
