Which two conditions should be avoided when using rope?

The correct answer identifies the importance of avoiding excessive exposure to sunlight and moisture when using rope. Sunlight can degrade the materials used in rope, particularly synthetic fibers, leading to reduced strength and increased likelihood of failure. The ultraviolet (UV) rays from the sun can weaken the rope's structure over time, making it less reliable.

Additionally, moisture can have detrimental effects, particularly when it comes to natural fiber ropes. Water can lead to mold, mildew, and rot, which can significantly compromise the integrity of the rope. Even with synthetic ropes, moisture can reduce grip and cause slippage during use.

By avoiding these two conditions—excessive exposure to sunlight and moisture—you ensure that the rope remains durable and effective for its intended applications, ultimately enhancing safety and reliability in its use.
