　　例题10：

　　Paragraph 4: Thus a proportion of the total volume of any sediment, loose or cemented, consists of empty space. Most crystalline rocks are much more solid; a common exception is basalt, a form of solidified volcanic lava, which is sometimes full of tiny bubbles that make it very porous.

　　Paragraph 5: The proportion of empty space in a rock is known as its porosity. But note that porosity is not the same as permeability, which measures the ease with which water can flow through a material; this depends on the sizes of the individual cavities and the crevices linking them.

　　According to paragraphs 4and 5, why is basalt unlike most crystalline forms of rock?

　　It is unusually solid

　　It often has high porosity.

　　It has a low proportion of empty space.

　　It is highly permeable.
