Next week I am on vacation. While I am on a vacation, I will work on two projects.First, I will fix the washing machine. The washing machine has been broken for two weeks. To fix it, I will need three tools: a screwdriver, a wrench, and a clamp. It will take one day to fix the washing machine.Next, I will fix our back porch. This is a bigger project. It will probably take about two days to fix the back porch, and will require a screwdriver, a hammer, nails, and a saw. My vacation starts on Monday. I have a lot of work to do, but hopefully I can relax after I finish my work
Which of these tools will the author use more than once?
