Question

many teens dream of sleeping in each day, but it has nothing to do with laziness or lack of ambition. as children move into adolescence, their sleep cycles change. adolescents naturally stay up later and get up later because of how their bodies release melatonin, a hormone that regulates sleep. several studies show that teens cannot get out of this melatonin - induced sleep mode until at least 8:00 a.m., making later school start times desirable. changing school start times has several benefits, but administrators must also consider the drawbacks of changing a familiar schedule. parent work schedules one of the biggest concerns about changing school start times is parent work schedules. when school starts at 7:30 in the morning, most parents can see their teens off to school before going to work at 8:30 or 9:00. if school districts change start times to 8:00 or 8:30, parents will not be able to drive their kids to school and still get to work on time. this is a problem especially for parents of young children, as young kids need supervision while getting ready for school and waiting for the school bus. for teens, later school start times may lead to increased responsibility, as parents may have to go to work before school starts. this means teens will have to get themselves up, prepare breakfast and head to school on their own. transportation logistics another issue related to changing school start times is bus schedules and other transportation logistics. many school districts use the same buses for elementary school students as they do for high school students. if a bus driver has to drop students off at the high school and then pick up young kids for elementary school, delayed school start times would affect this schedule. school districts would need to delay start times for the elementary schools or invest in hiring additional bus drivers to transport the high school students. effects on extracurricular activities some students, parents and administrators are concerned about later school start times because of the possible impact on extracurricular activities. students who participate in sports, music groups, service learning clubs and other organizations typically meet for several hours after school. if school districts change their start times, these activities will be pushed to later in the day. this would make it which statement best describes how the author uses text structure to support her purpose? the author separates the supporting evidence into categories. the author uses a how - to structure to outline how to solve the various issues. the author lists all the benefits followed by supporting evidence. the author uses a problem - solution structure to address the various issues.

Explanation:

The text first presents the problem (teens' sleep cycle and school start - time issue) and then discusses possible solutions (changing school start times) and the associated drawbacks (parent work schedules, transportation logistics, effects on extracurricular activities). This is a problem - solution structure.

Answer:

The author uses a problem - solution structure to address the various issues.
