Final answer:
The word 'exciting' is the best replacement for 'glamorous' as it captures the lack of appeal and the mundane nature of jobs like cooking hamburgers, which the original sentence implies are not glamorous.
Step-by-step explanation:
The best word to replace glamorous in the sentence is exciting. The sentence mentions jobs open to high school students such as cooking hamburgers, indicating that these jobs may lack the allure or charm often associated with glamorous roles.
In this context, glamorous refers to something that is appealing or attractive in a way that seems exciting or exclusive - a quality that jobs like cooking hamburgers typically do not possess. Therefore, exciting captures the opposite of the mundane and unglamorous nature of these jobs.
In the given sentence, the word 'glamorous' means attractive or glamorous, so the best replacement for it would be the word 'exciting'.
