Answer 1

Answer:

A. a vee-shaped weld should be used

The author discusses the process of pressure welding, which involves heating the ends of metal pieces to a high temperature and then pressing or hammering them together to form a joint. Towards the end of the passage, the author mentions that for fairly thick bars of metals, a vee-shaped weld should be used. This means that when welding thick metal bars together, it's recommended to create a vee-shaped joint.
