When creating a prompt restatement, the writer must refrain from making up information due to the reinterpretation accuracy requirements. That means the reference to war and invaders should not be included. Yes, information can be imagined and included in the presentation. It just cannot be done in the first paragraph were language interpretation, word usage, and information accuracy are scored. save the imaginative topic explanation for the reasoning paragraphs.

Both reasoning paragraphs are well thought out, strongly explained, properly supported by examples, and well developed. There is a continuing cohesiveness and coherence to the overall presentation. There was a slight bump in the road though. The writer has a sentence formation problem in:
Therefore, it is grateful that the governments of countries that currently keep these antiques have well-preserved them.
For better clarity, it could have been presented as:
Therefore, the countries that own the artifacts will be grateful to the holding countries for having preserved the relics.
