Phones at Alder Creek (argument)
[1] Alder Creek Middle School should keep its rule that phones stay in lockers until the last bell. [2] Teachers logged each phone interruption for one month before the rule began and for one month after it. [3] The log shows thirty-one interruptions before the rule and six after, in the same classes with the same teachers. [4] The school's lockers were installed in 2015 and are painted green, which matches the school colors.
[5] One counselor reports that two students told her they feel calmer and more able to focus without a phone buzzing in their pocket. [6] Some parents ask for lunchtime access so they can text their children. [7] The office can already reach any student within a few minutes, and it has done so whenever a family needed to send an urgent message.
[8] If students may check phones at lunch, soon they will check them in class, then they will stop listening, and then the school's grades will fall. [9] Letting one rule slip would hurt every part of the school community. [10] The simplest way to protect learning is to leave the rule exactly as it is.
Ren wants to repair the reasoning in sentence [8]. Which addition would help most?
- A letter from several teachers saying they believe lunch phones would lead to trouble.
- Records from a school that allows phones at lunch, showing whether class phone use and grades changed.
- A second month of interruption counts from the same classes at Alder Creek.
- The cost of replacing the lockers if the school ended the rule.

Strong: relevant, and large and fair enough for what it says. Off topic: true, but it does not help show the claim. Too small: relevant, but too few cases to carry the claim. Faulty step: the reasoning from the evidence to the claim has a flaw.

The Pinewood Reading Hour (argument)
[1] Pinewood School should keep its daily quiet reading hour. [2] Students log what they read each day, and the logs show that the average student reads twenty-two more minutes a week than before the hour began. [3] The county's first public library opened in 1894, in a room above a hardware store. [4] Two sixth-grade teachers say their classes now ask for book suggestions every Friday, which they had not done before.
[5] Since the hour began in September 2023, Pinewood's average reading score has risen nine points, so the reading hour is raising scores. [6] In that same school year, Pinewood also hired two reading tutors, who work with small groups three days a week. [7] The tutors started in October and work with students who fell behind in earlier grades.
[8] A few families say the hour takes valuable time from math and science. [9] The school schedule shows that the hour replaces a study period, not a class. [10] The hour costs the school nothing to run and gives every student time to read for pleasure.
Noah marks sentence [5] as not sound. Which statement says what is wrong with its reasoning?
- It supports the claim with test scores, which measure a different thing from reading for pleasure.
- It claims that reading will lead to higher scores, then to success in later grades, with no evidence for the steps.
- It stretches one school's scores into a rule that a reading hour raises scores everywhere.
- It credits the reading hour for the rise in scores, although tutors who started the same year could explain it.
Ari wants to repair the reasoning in sentence [5]. Which addition would help most?
- More reading logs from Pinewood students for the same months.
- The number of books on the shelves of the Pinewood library.
- Scores from a similar school that hired reading tutors in the same year but has no reading hour.
- A letter from the principal saying the reading hour has been a great success.

A Later Bell at Eastgate (argument)
[1] Eastgate Middle School should start its day at 8:45 instead of 7:50. [2] In a survey of four hundred Eastgate students, three hundred ten said they get less than eight hours of sleep on school nights. [3] Doctors say that teenagers need eight to ten hours of sleep each night. [4] One science teacher kept notes for a week and says her first-period class looked sleepy on four of five days.
[5] A study of three hundred office workers found that people who start work at nine are less tired than people who start at seven, so students will be less tired at nine too. [6] The school's gym floor was replaced in 2016 and is used for games on Friday nights.
[7] Some families worry that a later bell would shorten after-school practice. [8] The athletic director says teams could practice in the early evening, when the fields are lit. [9] Bus drivers say their routes can fit a later start if the district keeps the same number of drivers. [10] A later bell is the best way to help students feel awake and ready to learn during the first class of the day.
Milo marks sentence [5] as not sound. Which statement says what is wrong with its reasoning?
- It claims that later starts lead to better sleep, then to better attention, then to better grades, with no evidence.
- It offers just two start times, seven o'clock or nine, as if no other time were possible.
- It stretches the answers of a few workers into a rule that fits people of any age.
- It uses a study of office workers to make a claim about students, who were not in the study.
Esme wants to repair the reasoning in sentence [5]. Which addition would help most?
- A study of six hundred office workers instead of three hundred.
- A letter from a student saying that a nine o'clock start would feel much better.
- A sleep study of students at a school that moved its start time to a later hour.
- A list of the bus routes the district runs before and after the bell.

Everyone Who Tries Out at Hollis (argument)
[1] Hollis Middle School should let every student who tries out for the spring play join the cast or crew. [2] Last year, fifty-eight students tried out for twenty-four acting parts. [3] The thirty-four students without a part joined the stage crew, and the show opened on time with every job filled. [4] The auditorium holds three hundred forty seats and has a balcony that is closed to the public.
[5] One crew member told the drama teacher that building the set was the best part of the school year. [6] Another teacher worries that a bigger crew means more noise backstage. [7] The drama teacher says that crew members work in assigned groups, each with a leader, so the backstage stays quiet during the whole show.
[8] A no-cut rule is the fairest rule because it is fair to everyone who wants to take part. [9] Fairness matters most when a school gives students a chance to try something new. [10] Hollis should keep its rule so that no student feels left out of the play, whether the part is large or small.
Bo marks sentence [8] as not sound. Which statement says what is wrong with its reasoning?
- It offers just two kinds of rule, no-cut or unfair, as if no other rule could be fair.
- It uses the idea that the rule is fair as its own reason for saying the rule is fair.
- It supports the rule with a fact about the auditorium, which has nothing to do with fairness.
- It stretches one crew member's happy year into a rule about how students feel in general.
