You could totally use Math Strategy here like Greg did but one easy way is that, look at terminology in question, is it mild or is it strong? “obsessively,” is pretty strong, so this should help us in choosing blank 2 where disposition could be eliminated as its mild.

Also we could eliminate candid as this question doesn’t hint us anything on honesty or frankness. Devoted is tge only option that comes closer to Obsessively personal memoirs…
