premise: The Rain Before It Falls is a lyrical novel written by British author Jonathan Coe. It describes the history of three generations of women directly or indirectly affected by events in post-war London and rural Shropshire. The novel contrasts with Coe's previous works in that it is almost apolitical, examining both the welcome and the undesirable legacies parents leave their children.
hypothesis: The Rain Before it Falls takes place after WWI.
reason: The scenario describes "post-war" England, but does not specify which war. This could be WWI or WWII.
