particular Asian nation
It would be better for your LR score ilt you use the phrase " in no particular Asian nation " instead. When you say "in particular" that connotes the naming of a nation, which you cannot do since it was not provided. Saying "no particular" avoids the need to name a specific country.
This reference is too general. It can refer to any year coverage. Refer to the specific years to help clearly inform the reader.
This is a redundancy since patently already means obviously. Do not repeat your word usage. Your synonym usage did that in this sentence.
period during 1980 and 2000
A period refers to successive, not selective years. This should say :... period ranging from 1980 to 2000...
to clearly refer to a time progression. Improper sentence formation blurrs your info clarity.
Specific areas for review and improvement:
1. Grammar range and sentence structuring
2. Vocabulary and synonym usage
Your analysis is acceptable but could be shorter. A single image reference should be no more than 7 paragraphs long.
