Explanation:

To solve the fill - in - the - blanks related to the American System, we analyze each blank based on historical knowledge:

Blank 1: "lines of ______ and transportation"

In the context of internal improvements (roads and canals) for facilitating commerce, the missing word should be related to the infrastructure that goes with transportation. "Communication" fits here as lines of communication (like postal roads, telegraph lines which were part of the broader internal improvement vision) along with transportation (roads, canals) would create closer national ties.

Blank 2: "benefiting mainly people in the ______ part of the country"

The American System's high tariffs were beneficial for the Northern part of the United States. Northern industries were protected by the tariffs as they could compete better against foreign goods, while Southern farmers (who relied on exporting cotton and importing manufactured goods) were hurt by the tariffs. So the word here is "Northern".

Blank 3: "Americans in the ______, most notably cotton plantation owners, opposed them"

As mentioned above, the Southern states, with their cotton plantation - based economy, opposed the high tariffs. So the word here is "South" (or "Southern" can also be used, but "South" is more in line with the context of regional division).

Final Answers for the Blanks:

1. For "lines of ______ and transportation": communication
2. For "benefiting mainly people in the ______ part of the country": Northern
3. For "Americans in the ______, most notably cotton plantation owners, opposed them": South
