Answer:

Explanation:
In this sentence, the correct word to complete the paragraph is "unfolding".

Meaning of unfolding:
The word "unfolding" means to open or spread out something that is folded. In the context of the sentence, it is referring to the action of opening or unfurling the Indian Flag.

Explanation of the sentence:
The sentence is describing a sequence of actions or events. It implies that after a certain action or event, the Indian Flag is unfolded and the National Anthem is sung.

The action or event before the unfolding of the Indian Flag is not mentioned in the given sentence. However, based on the context of the sentence, it can be inferred that the unfolding of the Indian Flag is an important or significant action that occurs after a previous action or event.

Reasons for choosing "unfolding" over "folding":
1. The sentence implies that the Indian Flag is being prepared or set up for a specific purpose. If the correct word was "folding", it would indicate the opposite action of closing or putting away the flag. However, the sentence does not suggest that the flag is being put away or closed.

2. The sentence mentions the singing of the National Anthem after the action of unfolding the Indian Flag. This suggests that the unfolding of the flag is a step that precedes the singing of the National Anthem. If the correct word was "folding", it would not make sense in the sequence of events described in the sentence.

Conclusion:
Based on the context and sequence of events described in the sentence, the correct word to complete the paragraph is "unfolding". This word accurately conveys the action of opening or spreading out the Indian Flag, which precedes the singing of the National Anthem.
