Which is a potential benefit of Bifilar Vibration Absorbers besides absorbing vibrations?

Explanation:
The device is used to suppress specific vibration frequencies transmitted through the rotor drive system, which protects structural components and maintains smooth operation. By damping or canceling these vibrations, the repetitive stresses on bearings, shafts, and joints are reduced. This decrease in fatigue loading translates into longer component life, which is the notable secondary benefit. Other options don’t fit as benefits: reducing fuel efficiency would be undesirable and not a feature of vibration absorbers; increasing tail rotor drag would be a drawback; and changing rotor speed isn’t a function of a bifilar vibration absorber.
