Which factor can influence the permanence of fingerprints on a surface?

• A. Age of the individual
• B. Material of the surface
• C. Condition of the environment
• D. All of the above

Answer: (D)

The permanence of fingerprints on a surface can be significantly influenced by the material of the surface, the condition of the environment, and the age of the individual, making "all of the above" the correct answer. The material of the surface plays a crucial role because different surfaces absorb or retain fingerprint residue differently. For example, porous surfaces like paper might hold onto fingerprints longer than non-porous surfaces like glass which can allow for smoother and clearer prints. The condition of the environment, such as temperature and humidity, can also affect the longevity of fingerprints. High humidity may cause the fingerprint to degrade more quickly, whereas a dry environment may help preserve it longer. Lastly, the age of an individual can contribute to the characteristics of their fingerprints. Factors such as skin oils, sweat production, and overall health can vary with age, affecting how well fingerprints adhere to surfaces. Together, these factors illustrate why the permanence of fingerprints is not determined by a single aspect but rather by multiple influences working in tandem.
