Final answer:
Ana's primary motivation is her love for her sister Elsa. Elsa copes with her anxiety by isolating herself but learns to embrace her powers. The central theme of 'Frozen' is the power of love, especially sisterly love.
Step-by-step explanation:
The questions are referencing the movie Frozen, which is part of Disney's animated lineup. To address the questions posed:
a) Ana's primary motivation in saving the kingdom is her love for her sister, Elsa. Ana wants to protect her sister and reassure her that she does not have to be alone with her fears and her powers. This reflects a shift in Disney movies where the love story is not necessarily romantic in nature but can also be familial, as seen in Ana's quest to save her sister and the kingdom.
b) Elsa copes with her anxiety over her magical abilities by isolating herself, believing this is the only way to protect others from her powers. However, throughout the movie, she learns to embrace her abilities and realize that she can use them for good. This is portrayed when she finally assumes her role as queen and uses her magic openly.
c) The main antagonist varies as the story develops, with characters like Prince Hans and the Duke of Weselton playing the role at different times. However, one could argue that Elsa's internal struggle with her powers also serves as a significant antagonist.
d) The central theme of the movie Frozen is about the power of love, particularly sisterly love, over fear and isolation. It emphasizes how love and acceptance can triumph over misunderstanding and misjudgment. This theme is also echoed in Disney's efforts to create strong, independent female characters that break away from traditional roles.
