Final answer:
The correct answer is option a. The special significance of the artwork to the artist likely lies in the portrayal of the perpetual cycle of events, as exemplified by the use of the Möbius strip which symbolizes endlessness. Considering the historical usage of spirals in art, it is clear that option 'b' is factually incorrect, making option 'a' the best answer.
Step-by-step explanation:
When considering what special significance a piece of art holds to the artist, it is important to understand both the historical and personal contexts that the artwork operates within. Looking at the provided information, it is suggested that the artist has used shapes like spirals to convey deeper meanings associated with time, nature, and continuity, harkening back to uses in various ancient civilizations.
A particularly compelling example is that of the Möbius strip, which embodies the perpetual cycle of creation and destruction, as demonstrated by the work related to the Gaza Strip. This indicates that the answer would be that the piece symbolizes the perpetual coming and going of things, and therefore, the correct answer is 'a' and not that no artist had used a spiral shape before which is clearly incorrect as the spiral has been used for centuries.
