Which statement about a single-acting cylinder is correct?

• The retraction of the piston is usually achieved by a spring.

• The piston speeds in extension and retraction can be set.

• Both piston sides will alternately be pressurized with compressed air.

• Work can be conducted during extension and retraction of the piston.

• It has a larger air consumption than a double-acting cylinder.
