Correct Answer: mundane

Solution : The correct choice is the second option.

Mundane means ordinary or lacking interest, and this sentence conveys the idea that Jacqueline associates retirement with escaping from the monotony or dissatisfaction with everyday life.

The meanings of the other options are as follows:

• Joyful means full of joy or happiness; experiencing or causing delight.
• Barbaric means savagely cruel, brutal, or primitive.
• Divine is related to or proceeding directly from God.

Therefore, the complete sentence is: "Jacqueline represents retirement as the final result of a long course of dissatisfaction with mundane life."
