"What" is used when there are unlimited options, while "which" is used when the options are limited. For example, when asking for a phone number, you would say, "What is your phone number?" The response could be, "My phone number is..." or "I do not have a phone number." When asking about preferences, such as "What fruit do you like more?" the word "what" is appropriate because there are many possible fruits to choose from. • Subtopic: Usage of "Do" and "Does" The auxiliary verbs "do" and "does" are used in questions and negative sentences. For example: - Do I/you/we/they...? - Does he/she/it...? Affirmative responses include: - Yes, you do. - Yes, I do. - Yes, he does. - Yes, she does. - Yes, it does. - Yes, we do. - Yes, they do. Negative responses include: - No, you do not. - No, I do not. - No, he does not. - No, she does not. - No, it does not. - No, we do not. - No, they do not.
