North Korea

Explanation:

North Korea is the country that has threatened world security in recent years because of its interest in becoming a nuclear power.  Its leader wants to impose himself as a world figure and uses the threat of nuclear weapon as a bargaining chip.

Venezuela : The country is on the verge of a civil war, totally collapsed, not a threat to the world, but to its people yes.

Vietnam: No major conflict happening there now, and certainly not an emerging nuclear power.

Iraq: still recovering from wars... not a nuclear threat.

this is a pretty broad question and can be a pretty lengthy answer. since 1900, women have gained a lot more rights and have become active in the workforce. with women being in the workforce, men play a larger role in family life. many family tasks are shared between men and women, whereas, women used to be the sole family caretakers.

that should get you started at least.
