Question

nationalism encouraged people with a shared identity to
convince other people to share their common bonds.
be open to other people’s traditions, ideas, and beliefs.
separate themselves from those who were unlike them.
declare war on all those who did not share their beliefs.

Explanation:

To solve this, we analyze the concept of nationalism. Nationalism emphasizes a shared identity and often leads to a sense of distinction from those with different identities.

• The red option ("convince others to share bonds") is not core to nationalism's typical effect (it's more about self - group cohesion, not proselytizing in this way).
• The orange option ("be open to others' traditions") goes against the often insular nature of nationalism.
• The blue option ("declare war on non - believers") is an extreme and not the most common or defining outcome of nationalism.
• The green option ("separate from those unlike them") aligns with nationalism's tendency to create a sense of "us vs. them" and emphasize the boundaries of the national group, leading to separation from those outside the shared identity.

Answer:

Green. separate themselves from those who were unlike them.
