A student writes: 'School should start at 8:30. A study of 9,000 teens found later starts raised attendance by 12 percent. The cafeteria should also serve better food.' Which claim does the writer support with evidence?

A student writes: 'Our school should install bottle fillers. Last year students bought 4,000 plastic bottles here. The first fully synthetic plastic was made in 1907. The gym is often crowded.' Which sentence gives evidence for the bottle filler claim?

A writer argues: 'Recess should be longer. Dr. Vega, a pediatrician who studies children's activity, says twenty minutes is too short for real play.' What does Dr. Vega's sentence supply that the first sentence does not?

A writer argues: 'The town should extend the bus route to Miller Road. A survey found 300 riders walk over a mile to the nearest stop. The town should also repaint the buses.' Which claim is asserted with no support?

A writer argues: 'The library should stay open until six. A sign-in log shows 45 students were still working there at closing time each Tuesday. Reading is important for everyone.' Which sentence supplies the evidence?

A writer argues: 'We should ban plastic bottles in the cafeteria. They fill three recycling bins a week. Students already carry refillable ones. The ocean covers 71 percent of Earth.' Which sentence is true but supports nothing about the ban?

A writer argues: 'Longer recess helps every student focus. Last Tuesday my friend Dev came back from a long recess and finished his math page quickly.' Why is that support weak for the claim as stated?

A writer argues: 'Later start times make students healthier. A survey shows 80 percent of students would prefer to start at 9:00.' Why does the survey fail to support the claim?

A writer argues: 'The library should open on Saturdays. Ms. Ortega, a librarian who has run weekend programs for ten years, says Saturday visits usually double a library's use.' What does Ms. Ortega's sentence add to the claim?

A writer argues: 'The bus route should reach Miller Road. A rider count found 300 people walk over a mile to the nearest stop.' True or False: the writer supports the route claim with evidence.

A writer argues: 'Recess should be twenty minutes longer. Everyone knows that is the right amount of time.' True or False: the second sentence gives evidence for the claim.

A writer argues: 'The school day is seven hours long. Students need more outdoor time. A tracking log shows sixth graders here spend only 22 minutes outside daily. The hallways should be repainted.' Which claim is backed by evidence?

A writer argues: 'Our town should add an evening bus. Many workers finish their shifts after the last bus leaves.' What would the writer still need to supply to support the claim?

A writer argues: 'The library should open earlier. A sign-in log shows 60 students wait outside by 7:30. The gym should open earlier too. More clubs would then have space.' Which sentence supports the library claim rather than the gym claim?

A writer argues: 'Plastic bottles should be banned here. Last spring I carried a refillable bottle for a month and never missed the machines.' Why is that support weak for the claim?

A writer argues: 'The town should add a stop at Elm Park. A count found 120 riders walk there from the Main Street stop. Buses in our town were first painted blue in 1998.' Which sentence is true but supports nothing about the new stop?

A writer argues: 'A later start is the only sensible plan. Anyone can see that it would work. Our first bell rings at 7:40.' Which statement best describes the support the writer gives?

A writer argues: 'Recess should be ten minutes longer, because afternoon behavior problems would drop.' Which evidence would support that claim?

A writer argues: 'The library should stay open later, because students need quiet study space. A count shows the library holds 12,000 books.' Why does the count fail to support the claim?

A writer argues: 'Bottled water should go. A waste audit counted 1,800 bottles in our trash last month. Bottled water also tastes worse than tap.' Which claim is asserted without support?
