what is the role of articular cartilage in a synovial joint?
to surround the medullary cavity of the bone
to provide a reduced friction surface for motion
to prevent the joint from having too much motion
to reduce friction between the bones and other structures like tendons and ligaments

Explanation:

For the first question, the meniscus is a C - shaped fibrous cartilage in the knee that acts as a shock - absorber. The anterior cruciate ligament is a ligament (not cartilage) that stabilizes the knee. The joint capsule is a fibrous structure that encloses the joint. The bursa is a fluid - filled sac that reduces friction.
For the second question, articular cartilage covers the ends of bones in a synovial joint. Its main function is to provide a smooth, reduced - friction surface for motion. Surrounding the medullary cavity is not its function. Preventing too much motion is more of a ligament's role. Reducing friction between bones and other structures like tendons and ligaments is the job of bursae.

Answer:

First question: Meniscus
Second question: To provide a reduced friction surface for motion
