The most likely to be the cause of Martha’s discomfort in her knees and hips is osteoarthritis.

Osteoarthritis is a prevalent join disease that often affects elderly and middle-aged people. This disease is also commonly referred as the “wear and tear” of the joints, but most people now know that osteoarthritis involves the cartilage, entire joint, ligaments, bone, and joint lining. Joint pain is strongly linked with a person’s bodyweight.

the correct answer is 2.

a slump in geology means a mass movement process of slope failure. a mass of rock or unconsolidated material drops along a slip surface. in other words, rock layers move a short distance down the slope. the slump block is an intact block (2), without any landslide material.

in this image, 1 is the surface of rapture (scarp), 2 the slump block, 3 main scarp (crown), 4 base of rapture with debris flow.

slumps are caused by clear cutting on unstable soils and the sagging of earth, in coastal areas they are due to wave infiltration.
