问题如下：
Which of the following statements about Big Data is not correct:
选项：
A.
Big Data is characterized by volume, velocity, and variety.
B.
Unstructured data items are more often quantitative than qualitative in nature.
C.
Structured data items can be organized in tables.
解释：
考点：Big Data
解析：选项B的说法是错误的，混淆了structured data与Unstructured data，Unstructured data更多的是一些定性的。
正确的表述应该是Unstructured data items are more often qualitative than quantitative.
老师，怎么感觉B对的呢，因为unstructured的量更大但是质较低啊，比如监控数据，很多但是很乱啊。
