Choose the correct variant in brackets. The current theory for star formation is that stars form within (giant molecular / dwarf ionized) clouds. Stars form where there are (diffuse regions / dense cores) within clumps of gas and dust in these clouds. The formation of (an earth-like planet / a protostar / a black hole) involves the rapid collapse of infalling gas onto a dense core due to gravity. As a protostar shrinks, its rate of spin (decreases / increases). This allows subsequent infalling gas to accumulate at the (poles / equator) of the protostar; this material tends not to accummulate at the protostar's (poles / equator) due to its spinning motion. As the protostar continues to evolve, it emits infrared radiation. When it has nearly reached its final mass, it is called a (neutron star / Wolf-Rayet star / T Tauri star). These objects produce strong stellar winds.

The current theory for star formation is that stars form within giant molecular clouds. Stars form where there are dense cores within clumps of gas and dust in these clouds. The formation of a protostar involves the rapid collapse of infalling gas onto a dense core due to gravity. As a protostar shrinks, its rate of spin decreases. This allows subsequent infalling gas to accumulate at the equator of the protostar; this material tends not to accummulate at the protostar's poles due to its spinning motion. As the protostar continues to evolve, it emits infrared radiation. When it has nearly reached its final mass, it is called a Wolf-Rayet star. These objects produce strong stellar winds.
