Question

what was a significant consequence of western expansion? *
preservation of native american lands
complete ecological stability
environmental damage and species extinction
environmental conservation
what characterized the political parties of this era? *
complete political consensus
single - party system
two - party system with distinct ideological positions
no meaningful political differences

Explanation:

• For the first question: Western expansion led to settlers taking Native American lands, disrupting ecosystems (so not preservation or ecological stability). It was more about exploitation than conservation. Environmental damage (like deforestation, over - hunting) and species extinction (e.g., passenger pigeon decline) were common.
• For the second question: In many eras (e.g., US history with Democrats and Republicans), there was a two - party system. There was no complete consensus (parties had different views on issues like slavery, economic policies in some eras). A single - party system is not typical in many Western democracies during expansion eras, and there were meaningful political differences.

Answer:

• First question: Environmental damage and species extinction
• Second question: Two - party system with distinct ideological positions
