On the interference scale, which descriptor corresponds to Marginal?

• A. Annoying, Does not cause interruptions.
• B. Marginal, Causes intermittent interruption.
• C. Disruptive, Causes constant interruption.
• D. Severe, Causes complete interruption.

Answer: (B)

Interference on this scale is described by how often and how severe the disruption is. Marginal means the interference causes interruptions only intermittently—the faults appear sporadically rather than all the time. It’s more than a mere nuisance, but not constant or complete. The other descriptors map to different patterns: annoying implies a nuisance without actual interruptions, disruptive means constant interruption, and severe implies a complete interruption. So, the descriptor that matches Marginal is intermittent interruption.
