Read the two texts about Pluto’s classification.
Text A (astronomy blog, 2019): Pluto was discovered in 1930 and was considered the ninth planet for decades. In 2006, the International Astronomical Union (IAU) voted to redefine “planet,” and Pluto was reclassified as a dwarf planet because it has not cleared its orbital neighborhood. The author argues this change improved scientific accuracy, even if it disappointed the public.
Text B (opinion column, 2021): Pluto, found in 1931, was unfairly “demoted” in 2005 after a small committee changed the rules. The columnist claims Pluto meets the most important idea of a planet—being round and orbiting the Sun—and says the reclassification was driven by politics and popularity, not science.
Which disagreement is primarily factual rather than interpretive?
Whether the decision was driven by politics or by science.
Whether Pluto was discovered in 1930 or 1931.
Whether Pluto’s reclassification improved scientific accuracy.
Whether Pluto “should” be considered a planet today.
Explanation
This question tests analyzing cases where two texts provide conflicting information on the same topic, identifying specific points where texts disagree on matters of fact (objective, verifiable disagreements) or interpretation (subjective differences in understanding significance, causes, or meaning). Two types of conflicts: Factual conflicts involve disagreement on objective, verifiable information—dates, numbers, events, who did what, when things happened (Text A: "discovered in 1930"; Text B: "found in 1931"—factual disagreement on discovery year, astronomical records can verify which is correct). Interpretive conflicts involve disagreement on subjective judgments—significance, importance, primary causes, character/motives, implications (whether reclassification "improved scientific accuracy" vs was "unfair" and "driven by politics"—different value judgments about same decision). Text A states Pluto was discovered in 1930 and reclassified in 2006, while Text B states it was found in 1931 and the change happened in 2005—these are factual conflicts about verifiable dates that historical records can confirm. Answer C correctly identifies the discovery date disagreement (1930 vs 1931) as primarily factual rather than interpretive—this is an objective, verifiable fact that astronomical records can definitively resolve. The other options identify interpretive disagreements—A asks about whether reclassification improved accuracy (subjective judgment); B asks whether decision was driven by politics or science (interpretation of motives); D asks whether Pluto "should" be considered a planet (normative/value judgment). The question asks which disagreement is "primarily factual," and only the discovery date meets this criterion as an objective, verifiable historical fact rather than a matter of interpretation or judgment.
Read the two texts about the first powered flight by the Wright brothers.
Text A (biography excerpt): On December 17, 1903, Orville Wright piloted the first successful powered airplane flight at Kitty Hawk, North Carolina. The first flight lasted 12 seconds and covered 120 feet. The author argues the brothers’ careful testing and engineering skill were the main reasons they succeeded before anyone else.
Text B (popular history article): The Wright brothers achieved powered flight on December 14, 1903, when Wilbur briefly lifted off the ground for about 10 seconds and went roughly 100 feet. The article suggests luck and strong winds mattered more than planning, and that other inventors were just as close to success.
Which pair of statements directly contradict each other?
Text A: “careful testing and engineering skill were the main reasons” vs. Text B: “other inventors were just as close to success.”
Text A: “December 17, 1903” vs. Text B: “December 14, 1903.”
Text A: “at Kitty Hawk, North Carolina” vs. Text B: “strong winds mattered.”
Text A: “The first flight lasted 12 seconds” vs. Text B: “the flight lasted about 10 seconds.”
Explanation
This question tests analyzing cases where two texts provide conflicting information on the same topic, identifying specific points where texts disagree on matters of fact (objective, verifiable disagreements) or interpretation (subjective differences in understanding significance, causes, or meaning). Two types of conflicts: Factual conflicts involve disagreement on objective, verifiable information—dates, numbers, events, who did what, when things happened (Text A: "December 17, 1903"; Text B: "December 14, 1903"—factual disagreement on date, historical records can verify which is correct). Interpretive conflicts involve disagreement on subjective judgments—significance, importance, primary causes, character/motives, implications (whether success was due to "careful testing and engineering skill" vs "luck and strong winds"—different interpretations of causal factors). Text A states the first powered flight occurred on December 17, 1903, while Text B states it happened on December 14, 1903—this is a direct factual contradiction about when the historic event occurred, which historical documentation can definitively resolve. Answer D correctly identifies this date contradiction (December 17 vs December 14) as statements that directly contradict each other—both cannot be true, one must be wrong about this objective historical fact. The other options do not represent direct contradictions—A shows minor difference in flight duration (12 vs 10 seconds) but both are approximations; B compares unrelated statements (location vs wind importance); C contrasts interpretive views on causation (engineering skill vs luck) which can coexist as different perspectives. Only the date disagreement in D represents mutually exclusive factual claims where accepting one requires rejecting the other.
Read the two sources about the 1991 eruption of Mount Pinatubo.
Text A (Science news brief): A science brief says Mount Pinatubo erupted in June 1991. It reports that scientists’ warnings led to large evacuations and saved many lives. The brief adds that ash and sulfur gases entered the atmosphere and contributed to a temporary global cooling effect.
Text B (Community interview): In an interview, a community leader says the “main eruption” was in May 1991 and argues that officials focused too much on global climate discussions instead of local needs. The leader claims evacuations were late for some villages and that long-term housing problems were the most important outcome.
Why is this disagreement important to evaluate when learning about the eruption?
Because it proves that volcanoes never affect climate.
Because it shows that interviews are always wrong and science briefs are always correct.
Because it suggests Mount Pinatubo is not a real volcano.
Because different eruption dates and different views of the response can change how we judge whether warnings were effective and what impacts mattered most.
Explanation
This question tests analyzing cases where two texts provide conflicting information on the same topic, identifying specific points where texts disagree on matters of fact (objective, verifiable disagreements) or interpretation (subjective differences in understanding significance, causes, or meaning). Two types of conflicts: Factual conflicts involve disagreement on objective, verifiable information—dates, numbers, events, who did what, when things happened (Text A: "The treaty was signed in 1918"; Text B: "The treaty was signed in 1919"—factual disagreement on year, one must be wrong or both wrong, research can verify correct date). Interpretive conflicts involve disagreement on subjective judgments—significance, importance, primary causes, character/motives, implications (Text A: "The invention revolutionized communication"; Text B: "The invention had modest impact"—both may accept same factual events but interpret importance differently; historians analyzing same Civil War battle may agree on facts but disagree whether economic or political factors were primary cause—different emphasis/interpretation, multiple reasonable views possible). The texts disagree factually about timing (June vs. May 1991) and interpretively about response effectiveness (Text A: scientists' warnings saved lives; Text B: evacuations were late, officials focused too much on global climate). These disagreements matter because they affect our understanding of disaster preparedness effectiveness and what lessons to draw. If warnings were timely and effective (Text A), it validates scientific monitoring systems; if they were late with misplaced priorities (Text B), it suggests need for better local focus. The correct answer A recognizes that different dates and different assessments of the response change how we evaluate the event's lessons about warning systems and priorities. The incorrect answers are clearly wrong: B claims it proves volcanoes never affect climate (both texts acknowledge climate effects), C makes an absolute claim about source reliability not supported by the question, and D absurdly suggests the volcano isn't real.
Read the two sources about the eruption of Mount St. Helens.
Text A (Science website): Mount St. Helens erupted on May 18, 1980. The website reports that 57 people died and that the eruption triggered a massive landslide and ash cloud. It emphasizes that scientists’ monitoring and hazard zones saved lives because many people stayed away from the most dangerous areas.
Text B (Memoir excerpt): A local resident’s memoir says the eruption happened on May 8, 1980, and claims “over 100” people died because warnings were confusing and officials reacted too slowly. The writer argues that the event shows how authorities often underestimate natural disasters.
Which choice best identifies the conflict between the texts?
They disagree on the eruption’s date and death toll (factual), and they also differ on how effective officials and scientists were (interpretive).
They disagree only because one text is written in first person and the other is not.
They agree on the date and deaths but disagree about whether ash was produced.
They disagree only about whether Mount St. Helens is a volcano.

In this case, Text A states the eruption occurred on "May 18, 1980" with "57 people died," while Text B claims it happened on "May 8, 1980" with "over 100" deaths. These are factual conflicts—dates and death tolls are objective, verifiable information. Additionally, Text A emphasizes that "scientists' monitoring and hazard zones saved lives" while Text B argues "warnings were confusing and officials reacted too slowly"—this is an interpretive conflict about how effective the response was. The correct answer A accurately identifies both types of conflict: factual disagreement on date and death toll, plus interpretive disagreement on effectiveness of officials and scientists. The incorrect answers miss key elements: B absurdly claims they disagree about whether Mount St. Helens is a volcano, C wrongly states they agree on date and deaths when they clearly don't, and D irrelevantly focuses on narrative perspective rather than content disagreement.
Read the two sources about school start times for middle school students.
Text A (Pediatrician’s column): A pediatrician argues that starting school later improves learning because teens’ bodies naturally fall asleep later. The column cites a district that shifted start time from 7:30 a.m. to 8:30 a.m. and reports fewer tardies and better average grades. It concludes that sleep is the most important factor in academic success.
Text B (School board statement): A school board statement agrees sleep matters but says later start times create major transportation problems and reduce after-school activity time. It notes that the same district saw bus costs rise and sports practices end later. The statement argues that family schedules and safety (kids waiting in the dark) should be weighed as heavily as sleep.
How do the texts differ in their presentation of the issue?
Text A claims the start time changed from 8:30 to 7:30, while Text B claims it changed from 7:30 to 8:30.
Text A and Text B disagree about whether schools have buses.
Text A focuses on benefits to sleep and academics, while Text B emphasizes trade-offs like cost, scheduling, and safety.
Text A says sleep does not matter, while Text B says sleep is the only thing that matters.

In this case, both texts agree on basic facts (the same district shifted from 7:30 to 8:30 a.m.) but present different aspects and priorities. Text A emphasizes positive outcomes (better sleep leading to fewer tardies and better grades, concluding sleep is "most important"), while Text B acknowledges sleep matters but emphasizes negative trade-offs (increased bus costs, later sports practices, safety concerns about darkness). This represents different emphasis rather than factual contradiction—both perspectives can be simultaneously true as they focus on different consequences of the same policy change. The correct answer A accurately captures how the texts differ in presentation and emphasis without contradicting each other factually. The incorrect answers misrepresent the texts: B falsely claims Text A says sleep doesn't matter, C introduces an irrelevant point about whether schools have buses, and D incorrectly reverses the time change direction in one text.
Read the two texts about the invention of the printing press in Europe.
Text A (school article): Johannes Gutenberg developed a practical movable-type printing press in the mid-1400s, and by 1500 European printers had produced over 20 million books. The article argues the press rapidly increased literacy and helped spread new ideas during the Renaissance and Reformation.
Text B (historian interview transcript): Gutenberg’s press mattered, but the interview says early printing was slower and more limited than people imagine. It claims that by 1500 the number of printed books was closer to 8 million, and that literacy rose mainly because cities grew and schools expanded. The historian argues printing supported change but did not cause it by itself.
Why is this disagreement between the texts important to evaluate?
It affects how we understand both the scale of early printing (number of books) and whether printing was a main driver of social change or just one factor.
It shows that neither text mentions Europe.
It proves that Gutenberg never existed.
It only changes how we spell Gutenberg’s name, not the meaning of the topic.
Explanation
This question tests analyzing cases where two texts provide conflicting information on the same topic, identifying specific points where texts disagree on matters of fact (objective, verifiable disagreements) or interpretation (subjective differences in understanding significance, causes, or meaning). Two types of conflicts: Factual conflicts involve disagreement on objective, verifiable information—dates, numbers, events, who did what, when things happened (Text A: "over 20 million books" by 1500; Text B: "closer to 8 million" by 1500—factual disagreement on book production numbers). Interpretive conflicts involve disagreement on subjective judgments—significance, importance, primary causes, character/motives, implications (Text A: press "rapidly increased literacy and helped spread new ideas"; Text B: "printing supported change but did not cause it by itself"—different views on printing's causal role). The disagreement includes both factual elements (20 million vs 8 million books produced) and interpretive elements (whether printing was a primary driver of social change or just a supporting factor), making evaluation important for understanding both the scale of early printing and its role in historical change. Answer A correctly identifies why this matters: "It affects how we understand both the scale of early printing (number of books) and whether printing was a main driver of social change or just one factor." The factual disagreement about book numbers affects our understanding of printing's reach and impact, while the interpretive disagreement affects how we understand causation in historical change. Options B, C, and D are clearly wrong—the disagreement doesn't prove Gutenberg never existed, both texts mention Europe, and this goes far beyond spelling to substantive historical questions about technology's role in social transformation.
Read the two texts about plastic pollution in oceans.
Text A (environmental nonprofit report): The report states that about 8 million metric tons of plastic enter the ocean each year. It argues the biggest source is mismanaged waste from land, carried by rivers into the sea. The report says banning certain single-use plastics and improving waste collection would quickly reduce harm to wildlife.
Text B (industry research summary): The summary estimates closer to 4 million metric tons of plastic enter oceans annually. It claims lost fishing gear and shipping-related waste are the largest contributors. It argues bans are less effective than investing in cleanup technology and better recycling markets, because consumer products are only a small part of the problem.
Which option best identifies the main points of conflict?
They disagree about whether plastic exists in the ocean at all.
They disagree only about which ocean has the most plastic, which neither text mentions.
They disagree about the yearly amount of plastic entering the ocean and about the main source (land-based waste vs. fishing/shipping), and they also recommend different solutions.
They agree on the amount of plastic but disagree only on whether recycling is possible.
Explanation
This question tests analyzing cases where two texts provide conflicting information on the same topic, identifying specific points where texts disagree on matters of fact (objective, verifiable disagreements) or interpretation (subjective differences in understanding significance, causes, or meaning). Two types of conflicts: Factual conflicts involve disagreement on objective, verifiable information—dates, numbers, events, who did what, when things happened (Text A: "about 8 million metric tons" yearly; Text B: "closer to 4 million metric tons"—factual disagreement on quantity; Text A: biggest source is "mismanaged waste from land"; Text B: largest contributors are "lost fishing gear and shipping-related waste"—factual disagreement on primary source). Interpretive conflicts involve disagreement on subjective judgments—significance, importance, primary causes, character/motives, implications (Text A recommends banning single-use plastics; Text B argues for cleanup technology and recycling—different policy interpretations). The texts show multiple conflicts: factually, they disagree on yearly plastic amounts (8 vs 4 million metric tons) and main sources (land-based waste vs fishing/shipping); they also recommend different solutions (bans vs technology/recycling). Answer A correctly identifies these main points of conflict: "They disagree about the yearly amount of plastic entering the ocean and about the main source (land-based waste vs. fishing/shipping), and they also recommend different solutions." Options B, C, and D are incorrect—both texts acknowledge plastic pollution exists; they disagree on amounts not just recycling possibility; neither text discusses which specific ocean has most plastic. This exemplifies how environmental texts can conflict on both measurable facts and policy recommendations.
Read the two sources about the Great Chicago Fire.
Text A (History textbook): The Great Chicago Fire began on October 8, 1871, and burned for about two days. The textbook says around 300 people died and about 100,000 were left homeless. It explains that dry weather, wooden buildings, and strong winds helped the fire spread quickly.
Text B (Online blog post): A blog post claims the fire started on October 6, 1871, and that “thousands” died. It argues that the main reason the fire spread was government corruption: the post says city leaders ignored safety rules and failed to fund a professional fire department.
Which point of disagreement is primarily factual (something that could be checked with evidence)?
Whether the fire was a significant event in Chicago’s history.
Whether corruption was the most important reason the fire spread.
The date the fire began and the approximate number of deaths.
Whether wooden buildings made the city more vulnerable to fire.
Explanation
This question tests analyzing cases where two texts provide conflicting information on the same topic, identifying specific points where texts disagree on matters of fact (objective, verifiable disagreements) or interpretation (subjective differences in understanding significance, causes, or meaning). Two types of conflicts: Factual conflicts involve disagreement on objective, verifiable information—dates, numbers, events, who did what, when things happened (Text A: "The treaty was signed in 1918"; Text B: "The treaty was signed in 1919"—factual disagreement on year, one must be wrong or both wrong, research can verify correct date). Interpretive conflicts involve disagreement on subjective judgments—significance, importance, primary causes, character/motives, implications (Text A: "The invention revolutionized communication"; Text B: "The invention had modest impact"—both may accept same factual events but interpret importance differently; historians analyzing same Civil War battle may agree on facts but disagree whether economic or political factors were primary cause—different emphasis/interpretation, multiple reasonable views possible). In this case, Text A states the fire "began on October 8, 1871" with "around 300 people died," while Text B claims it "started on October 6, 1871" with "thousands" died. These are factual disagreements—the start date and death toll are objective facts that historical records can verify. One text must be wrong about the date (historical records confirm October 8), and the death toll can be verified through historical documentation. The correct answer C accurately identifies these factual disagreements that could be checked with evidence. The other options focus on interpretive matters: A asks about the importance of corruption as a cause (subjective judgment), B asks about vulnerability from wooden buildings (both texts could agree on this), and D asks about historical significance (interpretive assessment).
Read the two texts about the eruption of Mount St. Helens.
Text A (USGS-style summary, 121 words):
On May 18, 1980, Mount St. Helens in Washington erupted after a magnitude 5.1 earthquake triggered a massive landslide. The lateral blast flattened forests and caused 57 deaths. Scientists had been monitoring the mountain for weeks and had warned that an eruption was likely, leading officials to create restricted zones. Although some people entered the area anyway, the monitoring and closures reduced the number of casualties. The eruption also provided valuable data that improved future volcanic hazard planning.
Text B (magazine feature, 127 words):
The May 18, 1980 eruption of Mount St. Helens took experts by surprise. Officials hesitated to restrict access because they feared harming local tourism, so many people stayed close to the volcano. When the mountain exploded, the tragedy showed that scientific warnings were unclear and that evacuations were poorly handled. The event is remembered less for improving hazard planning and more for revealing how unprepared communities can be when leaders delay action.
Despite their disagreements, what do both texts clearly agree on?
Exactly 100 people died, most of them tourists.
No scientists monitored the volcano before it erupted.
The eruption happened in 1979 and was caused mainly by heavy rain.
The eruption occurred on May 18, 1980, at Mount St. Helens in Washington.
Explanation
This question tests analyzing cases where two texts provide conflicting information on same topic, identifying specific points where texts disagree on matters of fact (objective, verifiable disagreements) or interpretation (subjective differences in understanding significance, causes, or meaning). Two types of conflicts: Factual conflicts involve disagreement on objective, verifiable information—dates, numbers, events, who did what, when things happened (Text A: "The treaty was signed in 1918"; Text B: "The treaty was signed in 1919"—factual disagreement on year, one must be wrong or both wrong, research can verify correct date). Despite their disagreements about preparedness and the value of scientific warnings, both Text A and Text B explicitly agree on the basic facts: "On May 18, 1980, Mount St. Helens in Washington erupted" (Text A) and "The May 18, 1980 eruption of Mount St. Helens" (Text B)—both texts state the same date, location, and event. This demonstrates that texts can have significant interpretive disagreements (whether officials were prepared, whether warnings were clear, whether the event improved planning) while still agreeing on core factual information. Option B correctly identifies what both texts clearly agree on—the date (May 18, 1980), the volcano (Mount St. Helens), and the location (Washington). The other options are false: A gives wrong date and cause, C gives wrong death toll and victim type, and D contradicts Text A which states scientists had been monitoring for weeks.
Read the two texts about why honeybees communicate with a “waggle dance.”
Text A (student science journal): When a honeybee finds a rich food source, it returns to the hive and performs a waggle dance. The angle of the dance shows the direction of the food compared to the Sun, and the length of the waggle shows distance. The article states this communication system is essential for colony survival because it helps many bees quickly gather nectar.
Text B (science news summary): Researchers agree bees perform a waggle dance, but the summary argues the dance is only one of several cues. It says smell and simple following behavior can be more important than the dance, especially when food is nearby. The summary suggests the dance is helpful but not essential, and colonies can still survive when the dance information is limited.
On what point do these texts disagree most clearly?
Whether the waggle dance is essential for colony survival or just one helpful cue among others.
Whether bees return to the hive after finding food.
Whether bees use the Sun to navigate at all.
Whether the waggle dance indicates direction and distance.
Explanation
This question tests analyzing cases where two texts provide conflicting information on the same topic, identifying specific points where texts disagree on matters of fact (objective, verifiable disagreements) or interpretation (subjective differences in understanding significance, causes, or meaning). Two types of conflicts: Factual conflicts involve disagreement on objective, verifiable information—dates, numbers, events, who did what, when things happened (both texts agree waggle dance indicates direction and distance—no factual conflict on this). Interpretive conflicts involve disagreement on subjective judgments—significance, importance, primary causes, character/motives, implications (Text A: dance is "essential for colony survival"; Text B: dance is "helpful but not essential"—different assessments of importance/necessity). Text A argues the waggle dance communication system "is essential for colony survival because it helps many bees quickly gather nectar," presenting it as a critical survival mechanism, while Text B argues "the dance is helpful but not essential, and colonies can still survive when the dance information is limited," presenting it as one useful tool among several. Answer B correctly identifies this as the clearest point of disagreement: whether the waggle dance is essential for colony survival (Text A's position) or just one helpful cue among others (Text B's position)—this is an interpretive conflict about the relative importance and necessity of the dance for bee colonies. The other options are incorrect—A misrepresents the texts (both agree bees return after finding food); C is wrong because both texts agree the dance indicates direction and distance; D is wrong because both texts acknowledge bees use the Sun for navigation. The core disagreement is interpretive: how important/essential is the waggle dance relative to other communication methods like smell and following behavior?
