Short explanation: We use "Does" to form a question in the present simple tense when the subject is "she" and the main verb is "write".
Step-by-step solution:
- The sentence is a question in the present simple tense, indicated by "often".
- The subject is "she", and the main verb is "write".
- For third-person singular subjects (he, she, it) in the present simple, we use the auxiliary verb "Does" followed by the base form of the main verb.
