The u. s. congress refused to ratify the treaty of versailles (1919) because
a) it punished germany too harshly.
b) the united states did not receive enough territory.
c) president wilson was against the league of nations.
d) it felt the league of nations would restrict america of its sovereignty.

The right answer is D.

Explanation:

The US joined the WWI rather late.  At that time, it wasn´t still evident to the public or to many members of Congress that the security and the interests of the USA would require active participation in world affairs after the end of the war. There have always been isolationist feelings in America and those were strong in the aftermath of WWI. Despite the fact that he had played a major role in the negotiations leading to the peace accord of Versailles, president Woodrow Wilson failed to persuade Congress to join the League of Nations.

the answer is "by providing data about careers and annual mean wages"

the best description of postwar writers might be progressive.

following the war, writers showed a tendency to work on artistic or social matters rather than political themes. while postwar literature may not have been the greatest period of english literature, the themes provided excellent critics a high number of novels. such examples include anthony burgess, anthony powell and frank kermode, all of which can be placed under the progressive view.
