What challenge did newly independent countries have to face as a result of unchanged colonial boundaries? the boundaries ignored the presence of mountains and rivers. the boundaries often put rival ethnic and religious groups in the same country. the boundaries put together people who had no desire for independence. the boundaries ignored ways for countries to have access to the oceans.

The correct answer is that: The boundaries often put rival ethnic and religious groups in the same country.

 Colonial boundaries often put ethnically different people one country. This resulted in hostility and conflict once the states were granted autonomy. The colonialists’ tactic of divide and rule also intensified conflict.
