Select the most appropriate option to fill in blank number 4.

The correct option to fill in blank number 4 is undaunted.

Step-by-step Explanation:

1. Contextual Analysis:
The passage describes a famous historical piece of art (specifically referencing the Dancing Girl of Mohenjo-daro). It highlights how art reflects the resilient, hopeful nature of humanity over time.

2. Meaning of the Options:

• undaunted: Not intimidated, discouraged, or disheartened by difficulty, danger, or disappointment; brave and determined. In combination with "ever hopeful human spirit," "undaunted" fits perfectly because it conveys a positive and resilient quality of the human spirit.

• unbelievable: Hard to believe or extraordinary. It does not fit logically when describing an enduring human spirit in this poetic context.

• ungrateful: Lacking gratitude. This carries a negative meaning that contradicts the positive, hopeful tone of the sentence.

• unsafe: Dangerous or exposed to risk, which is completely inappropriate for describing the human spirit here.

3. Conclusion:
Therefore, the word undaunted appropriately completes the phrase "the undaunted, ever hopeful human spirit."
