Thanks for your help. I just didn't understand your explination of the second sentence. The fact is I don't know if I should put present simple or present continuous in the first part of the sentence (eat or are eating), and this sentence is not a reply to the above mentioned question sentence...
Which one is correct and if you can explain:
1) What do you think about tourists who come to Nepal?
What do you think about tourists who are coming to Nepal?
2) They are eating (or eat?)different food and dress differently.
They are eating (or eat?)different food...
