It looks like the task is to identify the word that does not belong in each group. Here’s the reasoning behind the circled answers:

1. **Hobby**: All others are activities (singing, dancing, drawing).
2. **Morning**: This is a time of day, while the others are activities (singing, cooking, painting).
3. **Walk**: This is incorrectly circled. Correct: **Cook**, as walk and run are physical activities.
4. **What**: This is incorrect. Correct: **How** or **What**, as they are question words, but it seems circled anyway.
5. **Chair**: This is a noun, while the others are verbs or actions (sing, paint, swim).

Each answer is the one that does not fit the pattern of the others.
