In the U.S., a significant portion of copper is used for wiring in homes. The U.S. Commerce Department
reported in September that building permits for new homes increased 15% from August, indicating that
the demand for copper increased. Also in August, China reported that it would meet its full-year
economic growth target. This news resulted in copper suppliers expecting higher future copper prices.
If both of these factors occurred in the copper market on or around September 23, then which of the
answer choices gives the most likely trend line for copper prices from September 23 to September 30?
More information is needed; specifically, China's GDP last year must also be known.](https://content.bartleby.com/qna-images/question/7584944a-d614-4aed-bc27-d70409782e3c/2c1235fc-6afa-4b39-9795-b95f4144a2f0/8hnky3a_thumbnail.png)
