What are the benefits of open questions over closed questions?

Open questions permit the respondent to give a richer answer.Closed questions restrict the respondent to a limited choice of answer.In a survey, I can ask AND restrict your choices to just these 2 items:How do you feel today?A. GoodB. BadOr I can add numerous choices, including asking you to tell me your own choice of description:How do you feel today?A. HappyB. SadC. AngryD ExcitedE. Other -- [box, please specify the emotion that describes you today]OR, I can include a box that allows for 1,000 characters and ask you:Write about how you feel today (This is the most open method possible).
