M: When does the plane take off?
F: It has been arranged to take off at four fifteen but it’s delayed thirty minutes.

A: How can we increase production, Alan? Should we buy some more machines for the production line?
B: That’s not necessary. The real problem is that we can’t store any more raw materials. We need to increase storage space.
A: How. And the packing area, is that OK?
B: For the moment. As I said, storage is the problem.
