Most intense tornadoes ( EF3 to EF5 on the Enhanced Fujita Scale ) develop from supercells.

Most advanced nations like to use capital controls sparingly if at all, as in theory allowing markets freedom is a win-win situation for all involved: investors are free to seek maximum returns, and countries can benefit from investments that will develop their industry and infrastructure.

Most of what has been detailed in Hemichordate development has come from hemichordates that develop directly.

Most computer hardware engineers research, develop, design, and test various computer equipment.
