Answer:
C.
Explanation:
You can use the series of elimination for this. First, you look at A. Technology is not an understanding of something new, so we cross that out. Second, you look at B. Technology isn't a series of steps, so we can mark that one off. Third, you look at C. Technology is something created using science for use by society, so we can keep that in mind. Lastly, we check D. Technology doesn't match up to the definition, so we can cross that one out. The answer that would make the most sense would be D.
Answer:
- blue-black PHYSICAL PROPERTY
- crystalline PHYSICAL PROPERTY
- solid PHYSICAL PROPERTY
- sublimes to a violet-colored gas PHYSICAL PROPERTY
