what is an advantage of using air tools?\na) safety equipment is not needed.\nb) increases the amount of work that can be performed.\nc) are supplied by the dealership.\nd) all of the above.
Answer
Brief Explanations:
Air tools are powered by compressed air. They are generally more powerful than manual tools. This power allows them to perform more work in a given time. Safety equipment is always needed when using tools (so option A is wrong). And there is no guarantee that dealerships supply air tools (so option C is wrong). Since A and C are wrong, D (all of the above) is also wrong.
Answer:
B. Increases the amount of work that can be performed.
