I agree with you about a task. I believe that nobody make perfectly the task. It has to some defectives. Par example; in your task, you use different grammar like present simple, past simple, present perfect and future simple. I read it, it make me confuse a little. But I understood. So all suggestions are good to writer. When we know a defective, we can correct perfectly our task. And we will have less a mistake of grammar, word, phrase and sentence. I hope you will get my suggestions and can use well English soon. Thank you
