테국여행야 나는 지금 여행을 태국에 있는데 여기는 생각보다 공기가 너무 나빴어요. 그래서 1주전부터 기침이 멈추지않아서 진짜 힘들어요 ㅋㅋㅋ 하지만 테국사람은 너무 착하고 밥도 맛았으니까 여기에 있으면 행복하다. 그래도 외출할때는 미스크가 너무 중요하다.

Could you correct this sentence ? I have a question about the LED light , when I push the button , the led light doesn't turn on , it seems that the batteries have been already set , but it just doesn't seem to power no matter how many I push the button , is there anything wrong with the product? or do i need to do something to turn on the light ? or is there this possibility that the batteries are already dead? Thank you in advance ~~~~ !!!

The gap between rich and poor A lack of education could cause the gap between the rich and poor. The people who can't have enough education tend to have a lower wage compared to the people with sperior education. The companies hardly hire the people without any specific skills as they will not be the strong force of the companies. Therefore those who have low education can only get limited options for work. In worse case, some of these people will not even be able to get any job, and end up failing at making a living. That is the most possible reason to widen the gap between rich and poor. To address this issue , I suggest the government that they set up the opportunity to have an education to them. Every kid deserves to learn and persue a good life.

Productive "in" ? I want to be productive in teaching. Why is the preposition IN used before productive? Is there any other adjective that you can put before the preposition?

Set off? How can "Set off" mean to start something or to go somewhere?
