Question

Usually a professional trainer serves as the course instructor and uses a combination of hands -on activities and formal classroom training

Answer 1

Corrected sentence:
"Usually a professional trainer serves as the course instructor and uses a combination of hands-on activities and formal classroom instruction."

Alternative phrasings:
- More concise: "A professional trainer typically serves as the instructor, combining hands-on activities with classroom instruction."
- More formal: "Typically, a professional trainer acts as the course instructor and employs both hands-on activities and formal classroom instruction."
- More conversational: "Usually the trainer leads the course, mixing hands-on exercises with traditional classroom lessons."

Change notes: removed the extra space in "hands-on" and adjusted wording for clarity and consistency (replaced the repeated "training" with "instruction" in some options).
