OE
The first blank asks for a contrast with “distant future”; remote is a synonym trap, and proximate fits. Atavistic (manifesting or reverting to ancestral characteristics) events don’t make sense in context. Future discounting involves placing more of a premium on present than on future events, and pleasures are desirable while detriments are not. It follows that subjects will tend to want to promote or prolong (protract) present pleasures, not avert (avoid by turning away or aside) or rescind (revoke) them. This is the common tendency “even at the expense of” a rapid increase in or a large number of (proliferation) “future detriments.” Neither malady (illness) nor buttressing (reinforcing) fits in this context.
