Final answer:
The sentences in the passage demonstrate how Louise Nevelson used 'found materials' in her art, introduce Nevelson's significance as an artist, and provide specific details about one of her most famous works to support the author's thesis about her impact on the art world.
Step-by-step explanation:
The sentences from the passage each play a role in developing the author's thesis about Louise Nevelson's artistic practices and her contributions to the art world. For example, the sentence "She deliberately sought discarded items (she called them 'found materials') such as pieces of wood, tin cans, and pieces of items out of trash cans." can be identified as providing a specific example in support of the author's thesis. It demonstrates how Nevelson's unique approach to art using 'found materials' aligns with the broader points being made about her work.
The sentence "This saying was true for Louise Nevelson, one of the world's most celebrated sculptural artists." serves to introduce the author's thesis by highlighting Nevelson's prominence in the art world, thus setting the stage for the forthcoming discussion about her work.
Finally, "Sky Cathedral, one of Nevelson's most well-known sculptures, consists of 38 boxes of varying sizes." offers contextual evidence that supports the thesis by detailing a work that exemplifies Nevelson's artistic style and how it contributes to her legacy.
