1. You gave suggestions, advice and opinions about what to be done to solve their problems.
2. You used different modal verbs in the suggestions given.
3. You included linking words to give cohesion and coherence to the text (first, also, however, so besides, etc.).
4. You wrote the number of words asked (50 to 70 words).
5. You used grammar, vocabulary and spelling properly.

There are some aspects you should be careful. If it is necessary, study again the correct use of modal verbs. Do not forget to answer everything that is asked in the checklist and mention all the points that are required. It seems to be that you are getting better at using modal verbs; unfortunately your writing is not perfect yet. There are some points that you are forgetting about and checking the grammar structures, punctuation or the correct use of grammar tenses can help you make fewer mistakes the next time. Your writing is really good! There is always something that can be corrected, but you have learnt to use modal verbs in the right way to give suggestions, possibilities and prohibitions or advice. Excellent!
