Final answer:
The four competitive levels of SkillsUSA are local, district/regional, state, and national, where students like Michael, Sasha, and Giselle compete in different skill challenges.
Step-by-step explanation:
The four competitive levels of SkillsUSA include local, district/regional, state, and national. At the local level, competitions occur within a school or local area. The district/regional level involves several schools competing in the same geographic region. The state level sees winners from the district/regional competitions compete against each other. Finally, the national level includes winners from state competitions who compete for national titles. Examples of such competitions can involve students from Alabaster Concordia, Genoa, Mocksville, Tynneson, and West End, each bringing their unique strengths, such as Michael's essay writing, Sasha's debating skills, and Giselle's experience in directing student productions.
