I agree partly with this opinion.
Based upon? Where is the reasoning basis for your belief? That should be at least a single sentence reference to 2 related reasons or 2 single sentences referring to indepedent reasons.
a negative impact on their spiritual health.
I'm not exactly sure how this connect with the previous reference to mental health problems. These are 2 different reference points that need to be individually explained in separate paragraphs. Make sure the discussion reasons are connected through proper reasoning. Do not just give reasons for the sake of giving them. Such an error results in a lower C+C score for that paragraph and eventually, the overall scoring consideration.
practical ones
mother tough
Incorrect phrase usage. Practical ones does not clearly reference the problems created by the need to speak a foreign language. There is an LR and C+C disconnection in this sentence that leaves the reader confused as to the idea behind the sentence reference.You are dangerously coming close to an overall failing LR score by using English reference phrases incorrectly. People refer to "mother tongue" in reference to languages, not "mother tough". That is not even remotely close in meaning to the original phrase.
there is a wide range of disadvantages
You are not even proof reading at this point and it is very frustrating for me as the potential examiner. You are not even double checking the relevance of your word usage to the sentence. You were referring to missed advantages. This is a clear error as you are proceeding to mention positives of learning to speak a foreign tongue in a different country.
You need to brush up on your English colloquialisms, idioms, and other vocabulary usage. These will be the main reasons why you will get a failing score in an actual test. Your LR and C+C abilities are very poor at this point.
