Representation P1 Connection of Problem-Action relationship (P-A connection) Causality
P2 Non-explicit temporal expression (non-explicitness) Granularity
P3 Temporal proximity implied in medical terms (proximity hint) Non-explicitness
P4 Uneven granularity (uneven granularity) Non-explicitness
P5 Implicit internal sequence Non-explicitness
Reasoning R1 Problem starts before Action (P precedes A) Reasoning
R2 Qualitative temporal relation (qualitative relation) Reasoning
