9. Use what you have learned about compound sentences to improve the following mini-essay: 1. A robot is a mechanical device that can perform boring, dangerous and difficult tasks. 2. First of all, robots can perform repetitive tasks without becoming bored. 3. They are used in automobile factories to weld and paint. 4. Robots can also function in hostile environments. 5.

10. Possible improvement 1. A robot is a mechanical device that can perform boring, dangerous and difficult tasks. 2. First of all, robots can perform repetitive tasks without becoming bored; therefore, they are used in automobile factories to weld and paint. 4. Robots can also function in hostile environments; as a result, they are useful for exploring the ocean bottoms as well as deep outer space.

11. Part 2 6. Finally, robots can perform tasks requiring pinpoint accuracy. 7. In the operating room, robotic equipment can assist the surgeon. 8. For instance, a robot can kill a brain a tumour. 9. It can operate on a foetus with great precision. 6. Finally, robots can perform tasks requiring pinpoint accuracy. 7. In the operating room, robotic equipment can assist the surgeon. 8.

14.
