While researching a topic, a student has taken the following notes:

* In the late 1890s, over 14,000 unique varieties of apples were grown in the US.
* The rise of industrial agriculture in the mid-1900s narrowed the range of commercially grown crops.
* Thousands of apple varieties considered less suitable for commercial growth were lost.
* Today, only 15 apple varieties dominate the market, making up 90% of apples purchased in the US.
* The Lost Apple Project, based in Washington State, attempts to find and grow lost apple varieties.

The student wants to emphasize the decline in unique apple varieties in the US and specify why this decline occurred. Which choice most effectively uses relevant information from the notes to accomplish these goals?
