This was a relatively straightforward exercise. The passage to be read from Art History: The Basics was quite short, but the discussion on the definition of "art" was engaging and the examples were helpful. Although I'm sure the writers won't leave the issue unresolved, they ask a question that probably goes through the minds of many people: has the definition of "art" been stretched to the point where it is meaningless? And their brief comments about the roles of culture, history and language point out that the understanding of art has evolved and will continue to do so.
I had never heard of the material "jesmonite" before, so I had to look it up. I now know that it is "a composite material used in fine arts, crafts, and construction. It consists of a gypsum-based material in an acrylic resin" (Wikipedia).
The short excerpt was enough to convince me that the book is probably one I should order for reading and reference.
