Excerpt (about 165 words): On the night the storm knocked out the town's power, Leo followed the creek to the mouth of Miller's Cave, a place his grandmother called a knot in the earth. The rain had rinsed the air clean; even the bats kept quiet. Inside, the passages bent like question marks. Leo snapped a glow stick and clipped it to his backpack so he wouldn't vanish into his own shadow. He had brought his father's roll of neon surveyor's tape—a bright, flat ribbon—and, at the entrance, he tied one end to a gnarled root. As he edged deeper, he let the tape whisper from the roll, brushing the damp walls, marking his path. When the ceiling dropped low, he ducked and laughed nervously at the drip, drip, drip. The cave did not roar; it listened. Far in, a gust stole his breath, and Leo paused, feeling how small he was. Then he turned, fingers finding the ribbon, and followed that thin, steady line toward light.
Student draft: The author reworks the myth of the labyrinth by giving Leo a modern "thread" that helps him escape. [ADD EVIDENCE HERE].
Which sentence best adds evidence from the passage to support the student's claim?
He just runs out fast, which proves he didn't really need any help.
Leo ties a string to his phone so it glows and leads him out of the cave.
For instance, the narration explains that Leo uses a roll of neon surveyor's tape, "tied one end to a gnarled root" and lets the ribbon trail behind him—an echo of the mythic guiding thread.
The cave did not roar; it listened.
Explanation
Choice C accurately cites and integrates the detail about the surveyor's tape with a transition and commentary that connects it to the mythic thread. The other choices either misquote/distort the passage (A, B) or drop a quote without explanation (D).
Excerpt: Every school day, cafeterias serve hundreds of meals—and send too much to the trash. Food scraps, napkins, and paper trays are heavy, so schools pay to haul what could become soil. In one district pilot, after a middle school introduced clear sorting stations and a composting pickup, the volume of trash bags fell by 48 percent in six weeks, according to the facilities report. The program cost less than two dollars per student per month and cut cafeteria odors; sealed bins were removed daily instead of sitting overnight. Students learned quickly: with color-coded lids and simple pictures, contamination dropped, and volunteers needed only to guide the line for the first few days. Composting doesn't solve everything—uneaten, packaged items still go to donation or recycling—but it keeps what's natural in a natural cycle. When schools treat food as a resource, they save money on hauling, reduce methane from landfills, and give science classes real-world material to study.
Student draft: Our school should adopt composting because it's affordable and proven to reduce waste. [ADD EVIDENCE HERE].
Which revision best blends evidence smoothly into the paragraph?
According to the facilities report from the pilot, trash-bag volume "fell by 48 percent in six weeks," while the program cost less than two dollars per student each month, demonstrating both impact and affordability.
Composting reduced trash by almost 80 percent, so it obviously works better than anything else ever tried.
Composting doesn't solve everything, which shows that composting is the best option.
Students like pictures and colors on lids, so composting will be fun for everyone.
Explanation
Choice A accurately cites relevant statistics from the passage and connects them to the claim with clear commentary. The other choices misstate data (B) or offer irrelevant/unsupported points and dropped quotes without explanation (C, D).
Excerpt: By late afternoon the market tents sagged under a sky the color of tin. Mina counted the coins in Grandmother's shawl, barely enough for carrots and a knob of butter. They turned toward home when an old man, his basket empty but for a sprig of parsley, stopped at their table. He blinked at the last sweet roll on the cloth and smiled sadly. Without a word, Grandmother wrapped the roll and pressed it into his hands. "For your walk," she said. He bowed and went on, humming a tune that sounded like rain. That evening, wind shouldered the windows. Mina's stomach ached with hunger and worry. Then came a knock. Their neighbor stood soaking wet, holding a covered pot. "We made too much stew today," she said. "Share with us." Steam rose like a blessing. Mina thought of the old man's empty basket and Grandmother's open hands, and how the tune had followed them all the way home.
Student draft: The story suggests that generosity creates a circle of care in the community. [ADD EVIDENCE HERE].
Which sentence best adds evidence from the passage to support the claim?
Mina and Grandmother buy plenty of food, so they don't need help from anyone.
Steam rose like a blessing.
The old man immediately returns with a feast, proving that generosity always gets rewarded the same day.
After Grandmother gives away their last roll to a stranger, a neighbor soon arrives with stew, saying they "made too much stew today," which shows kindness returning through the community.
Explanation
Choice D accurately selects and explains a relevant moment—neighbor bringing stew after Grandmother's generosity—and connects it to the claim. The other choices contradict the passage (A), drop a quote without explanation (B), or distort events (C).
Excerpt: In cities, sun-baked streets and roofs store heat long after sunset, raising temperatures in ways that are not evenly shared. A recent study mapped one-mile grids and found that blocks with less than ten percent tree canopy measured up to seven degrees hotter than nearby park areas at midday. Heat pools where shade is scarce. The good news is that trees change that pattern quickly. In one neighborhood coalition project, volunteers planted fifty curbside trees along south-facing blocks. Within two summers, satellite thermographs showed afternoon surface temperatures up to four degrees lower on those streets, and residents reported cooler sidewalks and more people walking. While reflective roofs and lighter pavements also help, trees provide shade, habitat, and evaporative cooling. Young trees need watering and time to grow, but even saplings cast meaningful shade on narrow sidewalks. For neighborhoods prioritizing relief within a few years, adding trees is a practical first step that yields multiple benefits.
Student draft: Planting street trees can lower neighborhood temperatures in the near term, not just decades from now. [ADD EVIDENCE HERE].
Which revision best blends precise evidence with commentary?
Trees provide habitat and evaporative cooling, which is interesting.
In the coalition project described, fifty new curbside trees led to "afternoon surface temperatures up to four degrees lower" within two summers, indicating a measurable cooling effect in a short period.
Areas with little tree canopy were seven degrees cooler than parks, proving trees don't matter that much.
Reflective roofs can also help, so we should just do those instead of trees.
Explanation
Choice B accurately cites the short-term, quantified temperature drop and explains how it supports the claim. The other options either ignore timing and relevance (A, D) or misstate the comparison and confuse the data (C).
Text Excerpt: The courier pushed through the late-afternoon traffic, the city pulsing with horn bursts and the new soda jingle that floated from stoops and shop doors. The tune hooked the back of his mind and tugged; for a heartbeat his front wheel drifted toward the bright billboard swaying above the avenue. He shook himself, twisted his earbuds in, and tuned to a channel of gentle static—white noise like a curtain—and fixed his eyes on the route, a thin blue thread he refused to let snap.
Student Draft: This modern scene echoes the ancient Sirens: a tempting song threatens to pull a traveler off his course, but he survives by blocking the sound and focusing on his path. The author doesn't just copy the myth, though; he updates it to the noise of advertising and urban life. [ADD EVIDENCE] This shows how a traditional danger is remade into something familiar to readers today.
Which sentence best adds evidence from the passage to support the student's analysis?
The text says, "The tune hooked the back of his mind."
He stops and stares at the billboard for minutes, completely forgetting the delivery.
As the narrator describes, the jingle "tugged," nearly pulling his wheel off course, and he "twisted his earbuds in" to fill them with "gentle static," a modern parallel to sailors blocking the Sirens' song.
The city is loud, with "horn bursts" everywhere, so that explains everything.
Explanation
Choice C smoothly integrates precise phrases and explains how they parallel the Sirens myth, linking the modern details to the traditional pattern. A is a dropped quote with no commentary, B invents events not in the passage, and D cites irrelevant sound without connecting it to the myth.
Text Excerpt: At the makerspace, Lina's stepsiblings hovered over the soldering station, shooing her to the bin of stripped wires. "You can organize those," they said, while they glowed under club lights, presenting their bot to the mentor. At home, a retired engineer from down the hall saw Lina's sketches and offered a battered tub of spare parts. They met quietly, building evenings after homework. On the night of the regional showcase, the submission portal would close at midnight; Lina's code compiled with seconds to spare, and she hurried out so no one would see her name on the leaderboard. In the rush, one glove slipped from her pocket and fell beneath a workbench.
Student Draft: The story borrows the pattern of Cinderella but makes it new with technology and a neighbor instead of a fairy godmother. [ADD EVIDENCE] The familiar outline remains, yet the details feel grounded in real clubs and deadlines.
Which revision best blends evidence smoothly into the paragraph?
For instance, Lina is sidelined by her stepsiblings, then aided by a "retired engineer" who supplies tools, and her midnight race to submit mirrors the fairy tale's time limit while fitting a coding competition.
She literally wears glass slippers and dances at a ball, so it's obviously Cinderella.
The submission portal would close at midnight.
Lina organizes wires and works at a makerspace, which is kind of like a palace if you think about it.
Explanation
Choice A integrates multiple specific details with transitions and commentary, clearly showing how the modern story reworks the Cinderella pattern. B invents details not in the text, C drops a quote without explanation, and D offers a weak, irrelevant comparison.
Text Excerpt: In arguing that middle schools should start later, the author states research: "A 2019 study of three high schools that shifted start times by 50 minutes found absences dropped by 15 percent and first-period tardiness by nearly a third." The author adds that adolescents' circadian rhythms make early waking biologically difficult. Addressing costs, the piece admits that adjusting bus routes could be expensive but counters that "healthier, more alert students" would "reduce costs tied to nurse visits and disciplinary referrals." The column concludes that the community should pilot a later start for one year, collect data, and expand if results hold.
Student Draft: The reasoning is mostly sound because it uses specific data and anticipates a counterargument about transportation. However, the argument would be stronger if it showed results from more than one district. [ADD EVIDENCE] That would help readers judge whether the evidence is sufficient.
Which sentence best adds relevant evidence and evaluation to the student's paragraph?
Absences dropped, which proves the author is right.
The study showed absences dropped by 50 percent, so that's enough.
Bus drivers probably like sleeping in too, which helps the case.
The author cites "a 2019 study of three high schools" where "absences dropped by 15 percent," a relevant start; still, relying on a single study limits sufficiency, as results from additional districts would test whether the effect repeats.
Explanation
Choice D accurately cites the passage's evidence and adds commentary evaluating sufficiency and generalizability. A is a vague, dropped claim; B misstates the statistic; C introduces irrelevant speculation.
Text Excerpt: Proponents of community gardens often claim they make neighborhoods safer. In Cedar Heights, volunteers cleared a vacant lot and planted rows of greens last spring. According to police reports, in the six blocks surrounding the lot, reported vandalism fell by 12 percent between May and September compared with the same months the year before. The garden coordinator also noted that on harvest nights "you see people talking across the fence who never spoke before." While a few store owners argued that "crime is about policing, not plants," the article concludes that gardens reduce crime by bringing neighbors together and "reclaiming" neglected spaces.
Student Draft: The article presents a clear claim, but some evidence is limited or off-topic. The vandalism statistic might be relevant, yet the reasoning jumps from a correlation to a firm cause. [ADD EVIDENCE] The piece would benefit from broader data or a comparison neighborhood.
Which sentence best strengthens the student's evaluation by integrating evidence from the article?
You see people talking across the fence, which is nice.
Although the author points to a "12 percent" drop in vandalism near the garden, the report covers only one season in one area, and the conclusion that gardens cause safer streets overlooks other possible factors, making the reasoning overconfident.
The article proves that crime disappeared completely after the garden opened.
Store owners are wrong because community is always more powerful than policing.
Explanation
Choice B accurately references the statistic and adds clear commentary about limits and causation, evaluating relevance and sufficiency. A is a dropped anecdote, C distorts the evidence, and D makes an unsupported, irrelevant claim.
Excerpt: At Brookfield Middle, lunch used to end in an avalanche of trash bags. This semester, the green team tried a simple fix: three bins at the exit—recycling, compost, and landfill—monitored by student volunteers. The first week was messy, and a few students rolled their eyes. But after a quick demonstration in science classes, sorting sped up. "We went from seven bags a day to about four," said custodian Mr. Lee, "and they're lighter." Cafeteria manager Ms. Torres noticed something else: the sour smell faded once food scraps were diverted. After six weeks, the team weighed the bags and found that the volume of trash fell by nearly half. They also collected comments from classmates who liked seeing leftovers become soil for the school garden. Some worried the system would slow the line, yet in practice the color-coded lids and clear posters kept students moving. The change wasn't flashy, but the numbers—and the cleaner air—were hard to ignore.
Student Draft: The author argues that composting reduces waste at school, and the claim is supported by relevant, sufficient evidence. [ADD EVIDENCE FROM THE PASSAGE HERE] This makes the recommendation credible rather than just a feel-good idea.
Which sentence best adds evidence from the passage?
For example, after six weeks of sorting, the team "found that the volume of trash fell by nearly half," and Mr. Lee reported they "went from seven bags a day to about four," linking the program to measurable reductions.
The piece proves composting eliminated all waste at Brookfield, which shows total success.
The sour smell faded once food scraps were diverted.
Posters forced students to throw away recyclables, which made the cafeteria faster.
Explanation
Option A integrates precise, relevant data from the passage with a transition and commentary that ties evidence to the claim. The others overstate, drop evidence without explanation, or distort the text.
Excerpt: By the time the chain snapped, Eli had memorized every crack in the delivery route—and every excuse. He wheeled his bike into the narrow repair shop on Cedar, where the bell chimed and dust glowed in a shaft of light. An older man looked up from a truing stand. "Long day?" he asked, taking the warped wheel into his hands. Eli shrugged. "I keep getting lost," he said, hearing how small it sounded. The man's fingers moved calmly, plucking at spokes like strings. "Maps help," he said, "but so does listening." He showed Eli how to sight along the rim and tighten in pairs. Then, as they worked, he added, "You already know the route; trust your legs." When the wheel was true, he felt something inside click as well—like the man had fixed more than spokes. He turned to thank the man, but the stool by the stand was empty. The bell chimed again, although the door hadn't opened. On the counter lay a note—no, only a grease thumbprint in shape of an arrow.
Student Draft: The story updates the "wise guide" archetype by giving Eli brief, transformative help from the shopkeeper. [ADD EVIDENCE FROM THE PASSAGE HERE] The mentor appears just long enough to teach a lesson and then vanishes, which is a classic pattern.
Which revision best blends evidence smoothly into the paragraph?
The man gives Eli a map and then leaves, which is what mentors do.
Maps help, the man said.
The guide is magic because the bell rings with no one there.
As the shopkeeper advises, "You already know the route; trust your legs," and Eli realizes "the man had fixed more than spokes," showing guidance beyond a repair.
Explanation
Option D integrates two accurate quotes with a signal phrase and commentary that connects them to the mentor archetype. The other options misstate events, drop a quote without analysis, or make unsupported claims.
