In this task you will be given an answer to a question. You need to generate a question. The answer given should be a correct answer for the generated question.

Examples of this form of articulation are found in the hip, where the rounded head of the femur (ball) rests in the cup-like acetabulum (socket) of the pelvis, and in the glenohumeral joint of the shoulder, where the rounded head of the humerus (ball) rests in the cup-like glenoid fossa (socket) of the shoulder blade. The shoulder includes a sternoclavicular articulation joint.
how did the ball and socket joint get its name

Lake of the Woods is over 70 miles (110 km) long and wide, and contains more than 14,552 islands and 65,000 miles (105,000 km) of shoreline. It would amount to the longest coastline of any Canadian lake, except that the lake is not entirely within Canada. Lake of the Woods is also the sixth largest freshwater lake located (at least partially) in the United States, after the five Great Lakes.
how many acres is lake of the woods

Nuclear fusion powers a star for most of its life. Initially the energy is generated by the fusion of hydrogen atoms at the core of the main-sequence star. Later, as the preponderance of atoms at the core becomes helium, stars like the Sun begin to fuse hydrogen along a spherical shell surrounding the core. This process causes the star to gradually grow in size, passing through the subgiant stage until it reaches the red giant phase. Stars with at least half the mass of the Sun can also begin to generate energy through the fusion of helium at their core, whereas more-massive stars can fuse heavier elements along a series of concentric shells. Once a star like the Sun has exhausted its nuclear fuel, its core collapses into a dense white dwarf and the outer layers are expelled as a planetary nebula. Stars with around ten or more times the mass of the Sun can explode in a supernova as their inert iron cores collapse into an extremely dense neutron star or black hole. Although the universe is not old enough for any of the smallest red dwarfs to have reached the end of their lives, stellar models suggest they will slowly become brighter and hotter before running out of hydrogen fuel and becoming low-mass white dwarfs.
what characteristic of helium makes it a major constituent of the pulsating star mechanism
