How does the author suggest shooting a dialogue scene so that you have a key light in the right location for both of your actors?

Shoot part of the scene in the morning and part in the afternoon so that the sun changes location and lighting

Shoot the first part of the scene at night so you can fill in lighting in post

Add a large number of lights so that you can light exactly the way you need

Break the $180$ rule so that you can get the lighting you need
