The type of solar weather during which we can predict power grid operations on Earth to degrade is Coronal Mass Ejections
Coronal Mass Ejections are what we call the sudden bursts of plasma and charged ions released from the suns solar corona. These CMEs tend to occur during solar flares and release the charged ions into the solar wind.
Despite the presence of all of the options during a solar storm, the correct option is option 3, Coronal Mass Ejections because without the presence of the CME , solar wind and flares are not dangerous to the Earth. The charged ions from the CME collide and warp the Earth's magnetic field, removing it's protection and causing <u>power grid failures and radio communication disruptions throughout the Earth.</u>

Answer:
Grasslands arose during the period of cooling and drying of the global climate, which occurred during the Cenozoic Era (65.5 million years ago till present).
Grasslands are said to be in between a forest and a desert when it comes to rainfall ( they do not receive enough rainfall to grow trees like a forest but they contain lots of grass so they receive more rain than a desert)
