The Interstate Highway System, a grid across the flat Great Plains, has allowed enterprising scientists to get out in front of storms and sometimes directly observe tornadoes. A big advance came with the development of Doppler radar for meteorology. By emitting pulses of energy and detecting the reflected signal, the technology captures information about wind and precipitation. Radar allowed the detection of mesocyclones, which became the basis for tornado forecasts and a boon for chasers, who would stop at payphones periodically to call the lab for the latest radar intel.4Mark for ReviewMCQABCWhich choice best describes the function of the underlined segment in the text as a whole?ATo describe the spread of the highway system across the US midwest.BTo explain how advancement in technology helped meteorology.CTo provide insight into how the doppler radar functions.DTo highlight the hurdles tornado chasers face periodically.
