Question

read the excerpt from the joint statement by president roosevelt and prime minister churchill.
fifth, they desire to bring about the fullest collaboration between all nations in the economic field with the object of securing, for all, improved labor standards, economic advancement and social security;
this statement is based on the assumption that
○ improved labor standards, economic achievement, and social security are not always possible.
○ most countries will want to cooperate with the us and great britain after the war ends.
○ churchill and roosevelt have already developed a plan for international economic improvements.
○ all countries will cooperate to achieve common goals with regard to the world economy.

Explanation:

The excerpt states Roosevelt and Churchill desire full global economic collaboration to achieve shared economic and social goals. An assumption underlying this desire is that nations will cooperate to reach these common world economy objectives. The other options are unsupported: the statement does not suggest these goals are unachievable, focus on post-war cooperation with just US/UK, or mention an already-developed plan.

Answer:

all countries will cooperate to achieve common goals with regard to the world economy.
