Final answer:
The correct connecting words or phrases for Len's essay are 'in contrast' to show the opposition between the sisters' dark colors suggesting deceit and Cordelia's pale colors implying innocence, and 'however' to indicate that while the old king also wears pale colors, they convey his age and frailty, not innocence.
Step-by-step explanation:
To show a logical connection between ideas in Len's essay about the color choices in Abbey's King Lear: Cordelia’s Farewell, specific connecting words or phrases should be used. In the first part of the sentence, Abbey clothes the older sisters in blood-red and black fabrics to suggest their untrustful motivations; in contrast, he clothes Cordelia in pale colors and white to suggest her innocence. This opposition sets up a contrast between the sisters' malevolence and Cordelia's purity. The second part of the sentence discusses the old king also being dressed in pale colors; however, it switches the context to indicate a different meaning for similar colors, as these suggest his age and frailty. Such transitional words are crucial for guiding the reader through the essay's argument and supporting the use of color symbolism in Abbey's work.
