Try each quiz question before looking at the correct answer. Use the explanations to review missed ideas, then come back to similar questions until the pattern feels familiar.

Question 1

1. The earthquakes are too small in number to count as real warning signs
2. Normal sulfur dioxide levels suggest magma isn't approaching the surface (correct answer)
3. The scientists already raised the alert level in response to the earthquakes
4. Earthquake frequency naturally decreases right before an eruption

Explanation: When a question asks you to combine two sources, your job is to find where the information overlaps. Notice that Source A lists two warning signs—increasing earthquakes AND rising sulfur dioxide. Source B gives you the data for both: earthquakes jumped from two to fifteen per day, but sulfur dioxide "stayed normal the whole time." That second detail is the key. The answer that says normal sulfur dioxide levels suggest magma isn't approaching the surface is correct because Source A directly told you that sulfur dioxide rises "as magma moves closer to the surface." Since those levels stayed normal, the magma probably isn't rising—so even though earthquakes increased, one major warning sign is missing. That's why scientists stay calm. The choice claiming the earthquakes are too small in number to count is wrong—Source A says increasing quakes are a real warning sign, and fifteen a day is a clear jump. The option stating scientists already raised the alert level contradicts the transcript, which says "we haven't raised the alert level yet." And the claim that earthquake frequency naturally decreases before an eruption reverses Source A, which says quakes increase before an eruption. A helpful strategy: when a passage gives you a list of signs or conditions, check each one against the evidence. The right answer often hinges on the one condition that isn't met—here, the steady sulfur dioxide is the piece that changes the whole picture.

Question 2

1. Students who sleep 5 hours attend fewer classes, causing their lower quiz scores
2. Doctors consider 5 hours sufficient, so another factor must explain the low scores
3. The survey only measured students' guessing ability, not real memory
4. Extra sleep gives the brain more time to organize memories, improving recall (correct answer)

Explanation: When a question asks you to combine two sources, your job is to find where the evidence in one source explains the pattern in the other. Source A tells you why sleep matters (the brain organizes memories during deep sleep), and Source B gives you data showing the pattern (more sleep = higher scores). The right answer should connect that cause to that effect. That's exactly why "extra sleep gives the brain more time to organize memories, improving recall" is correct. Source A explains that deep sleep helps the brain store memories, and Source B shows students with 9 hours scored 88% while those with 5 hours scored only 60%. The science and the data point to the same conclusion. The claim that "students who sleep 5 hours attend fewer classes" invents a reason neither source mentions — never add outside information that isn't supported. The idea that "doctors consider 5 hours sufficient" contradicts Source A, which recommends nine to twelve hours; 5 hours is well below that. And "the survey only measured guessing ability" dismisses the data with no evidence — Source B clearly calls these memory quizzes, not guessing tests. Strategy tip: On paired-source questions, ask yourself, "Which answer uses BOTH sources together?" The correct choice usually links a cause from the text to a result in the data. Cross out any option that adds unmentioned facts, contradicts a source, or ignores one source entirely.

Question 3

1. Site B's coral never actually expelled its algae, so recovery wasn't possible there
2. Site C's normal temperatures caused Site B's coral to bleach through shared currents
3. Site B's water temperature never cooled down at any point during the study
4. Longer heat exposure likely killed more coral, leaving fewer able to recover (correct answer)

Explanation: Whenever a question asks you to combine two sources—like an article and a data set—your job is to use each source to explain the other. The article gives you the science, and the infographic gives you the numbers. Read the article for a cause-and-effect rule, then look for that rule playing out in the data. The article tells you that coral can recover "if water cools quickly," but that bleached coral "can die" if "high temperatures continue too long." Now check the data: Site A had heat for 3 weeks, while Site B had heat for 8 weeks—more than twice as long. Longer exposure matches the article's warning about coral dying, which explains why Site B recovered much less. The answer that longer heat exposure likely killed more coral, leaving fewer able to recover, connects both sources perfectly. The claim that Site B's coral "never actually expelled its algae" contradicts the data, which clearly says 85% bleached—bleaching is the expelling of algae. The idea that "Site C's normal temperatures caused Site B's coral to bleach through shared currents" invents a connection nothing in either source supports. And the statement that Site B's water "never cooled down at any point" is contradicted by the data showing 5% did recover—recovery requires some cooling. Strategy tip: On combining-sources questions, watch for distractors that contradict a specific number in the data. Always cross-check each answer against both sources—if a choice ignores or twists a stated fact, eliminate it immediately.

Question 4

1. Long gaming sessions likely leave these students with fewer free hours each evening to complete their assigned homework
2. These students probably chose harder classes, so their homework often takes longer than it does for lighter gamers
3. Long hours of quick-moving gameplay may weaken their attention for calmer activities such as reading and homework (correct answer)
4. These students may care less about school overall, which likely lowers their effort on the homework they are assigned

Explanation: This question asks you to connect what each source shows. Source B gives a pattern: as gaming hours rise, on-time completion drops (85% → 65% → 40%). Source A explains why—lots of quick-moving gaming can make calmer tasks like reading feel less engaging, so students lose focus. Only one answer uses both the pattern and the reason: that long hours of fast gameplay may weaken attention for slower activities such as homework. The answer about fewer free evening hours sounds sensible, but neither source mentions time running out. Source A points to focus, not a shortage of hours. The answer about choosing harder classes invents a detail—Source B never says heavy gamers took tougher classes, and it tracked 150 general sixth graders. The answer about caring less about school also adds an idea neither source supports; Source A blames reduced focus from stimulation, not a drop in how much students care. When you combine the numbers with the article's explanation, weakened attention is the one cause both sources actually back up.

Question 5

1. Reef Zone A, because its warm period lasted three weeks, under the four-week threshold Source A links to a good chance of recovery. (correct answer)
2. Reef Zone B, because a two-degree temperature rise is described in Source A as too mild to cause lasting damage to coral.
3. Reef Zone B, because its longer exposure to warm water gave the algae more total time to regrow inside the coral tissue.
4. Reef Zone A, because Source B states its water temperature never actually rose above normal levels during the observation period.

Explanation: Whenever a question asks you to "combine details from both sources," your job is to find the specific rule or fact in one source and apply it to the situation described in the other. Here, Source A gives you the key rule: coral recovery drops sharply when warm temperatures last more than four weeks. Source B gives you the data you need to test against that rule. Look at the timing. Reef Zone A stayed warm for three weeks — under the four-week threshold — so it falls into the "good chance of recovery" category. Reef Zone B stayed warm for five weeks, past the threshold, making recovery unlikely. That's why new algae growth most likely appeared in Zone A, whose warm period stayed under the four-week limit. The choice saying Zone B recovered because two degrees is "too mild to cause lasting damage" misreads Source A, which never calls a two-degree rise harmless — the danger depends on duration, not just amount. The choice claiming Zone B's "longer exposure gave algae more time to regrow" flips the science backwards: longer warm exposure harms coral, it doesn't help algae return. And the choice stating Zone A's temperature "never rose above normal" contradicts Source B directly, which clearly says both zones rose two degrees and lost color. Your takeaway: on cross-source questions, pinpoint the exact number or condition that acts as a "rule" (here, four weeks), then check each scenario against it. Watch for traps that quote real details but attach them to the wrong logic.

Question 6

1. They are likely less nutritious than farmers market tomatoes due to longer transport and time since harvest (correct answer)
2. They are more nutritious because they cost less than farmers market tomatoes
3. They traveled a shorter distance, making them fresher than farmers market tomatoes
4. They were harvested more recently, so vitamin loss is not a real concern

Explanation: Whenever a question asks you to combine two sources, your job is to find where the general rule in one source connects to the specific facts in the other. Here, Source A gives you a rule: produce loses vitamins the longer it sits after harvest, and shorter transport usually means more nutritious food. Source B gives you the data to apply that rule. Look at the numbers for supermarket tomatoes: they traveled 1,200 miles and were harvested 8 days ago, compared to farmers market tomatoes that traveled 40 miles and were harvested just 1 day ago. Applying Source A's rule, more travel time and more days since harvest mean more vitamin loss—so the claim that supermarket tomatoes are likely less nutritious due to longer transport and time since harvest is exactly what both sources support together. The claim that they're more nutritious because they cost less confuses price with nutrition—Source A never links cost to vitamins, so cheaper doesn't mean healthier. The claim that they traveled a shorter distance flatly contradicts the data: 1,200 miles is far longer than 40 miles. And the claim that they were harvested more recently, so vitamin loss isn't a concern reverses the facts—8 days is older than 1 day, and Source A treats vitamin loss as a real issue. Your takeaway: when a question says "based on both sources," check that your answer uses information from each source and doesn't contradict the data. Watch for traps that swap numbers or bring in an unrelated factor like price.

Question 7

1. Region 3's steady pollination rates may show that mixed pesticide use cancels out any harm to bees entirely
2. Region 1's pollination decline likely resulted from heavy pesticide use harming bee navigation (correct answer)
3. Region 2's rising rates likely mean that avoiding pesticides makes bees stronger than untreated colonies elsewhere
4. Region 3's mixed use likely explains why pollination there dropped faster than in the pesticide-free region

Explanation: The article explains a cause: neonicotinoids harm bees' navigation and shrink colonies. The infographic shows an effect: Region 1, which uses these pesticides heavily, had a 25% pollination drop. Combining the two, the conclusion that Region 1's decline likely came from heavy pesticide use harming bee navigation fits both sources without stretching past the evidence. The idea that Region 3's steady rates show mixed use cancels out any harm goes too far—mixed use with unchanged rates proves nothing about harm being erased, and the article says these chemicals do cause damage. The claim that Region 2's rise means avoiding pesticides makes bees stronger than untreated colonies twists the data; Region 2 simply avoided harm, and neither source compares it to untreated colonies. The statement that Region 3's mixed use explains a faster drop misreads the infographic, which says Region 3's rates stayed about the same, not that they fell faster than the pesticide-free region. When you combine sources, look for the conclusion each source actually supports together, and check every claim back against the exact numbers and wording given.

Question 8

1. Monarchs are flying shorter distances now, which confuses scientists' counting methods
2. Loss of milkweed habitat is destroying a food source monarchs depend on (correct answer)
3. The forests in Mexico have become too cold for monarchs to survive winter
4. Farming improvements caused butterflies to migrate to entirely new regions

Explanation: When a question asks you to combine information from two sources, your job is to find where the ideas connect. Don't rely on just one source—look for a detail in each that fits together like puzzle pieces. Here, Source A tells you monarchs depend on milkweed to lay eggs and feed caterpillars. Source B shows the population dropping sharply and mentions milkweed habitat shrinking 30 percent. Put those together: less milkweed means less food, which explains why the population is falling. That's why the answer about loss of milkweed destroying a food source monarchs depend on is correct—it uses evidence from both sources. The choice claiming monarchs are flying shorter distances and confusing counting methods invents information; neither source mentions shorter flights or counting errors. The option saying Mexican forests have become too cold twists Source A—it says monarchs need those forests to survive winter, not that the forests turned deadly. The choice about "farming improvements" causing butterflies to migrate to new regions gets the facts backward: Source B says farming shrank habitat, which hurts monarchs, and nothing suggests they moved somewhere new. A helpful strategy: watch for wrong answers that mention a real word from the passage (like "farming" or "forests" or "flying") but change its meaning. Test writers love this trap. Always ask, "Does this claim actually match what the source said, or does it just borrow a familiar word?" The best answer connects both sources with evidence you can point to.

Question 9

1. Skilled engineers only agreed to work during the flood season each year
2. Workers received higher wages during flood season, which attracted more laborers
3. The pyramids required more limestone blocks only during the flood season months
4. Farmers became available as laborers when the Nile flooded their unusable fields (correct answer)

Explanation: When a question asks you to combine two sources, your job is to find the idea that connects them. Here, Source A explains who the workers were and why they were available, while Source B gives you the numbers showing that worker counts spiked during flood season. The correct answer must be supported by both. Look at the key detail in Source A: most laborers were "seasonal farmers who worked during the Nile River's flood season, when their fields were underwater and unusable." That's your cause. When the Nile flooded, farmers couldn't work their fields, so they became free to help build pyramids. Source B confirms this pattern held for all three pyramids—each shows higher worker numbers during flood season. So the answer that farmers became available when the Nile flooded their unusable fields is directly backed by both sources. The choice about skilled engineers only working during flood season contradicts Source A, which says skilled crews worked "year-round." The claim about higher wages attracting workers sounds reasonable, but neither source mentions pay at all—it's invented information. The idea that pyramids needed more limestone only during flood months confuses when workers were available with when materials were needed; nothing in either source says block demand changed by season. Your takeaway: on cross-source reading questions, beware answers that "sound logical" but aren't actually stated (like the wages trap). Always point to a specific line in the text that proves your choice—if you can't find evidence, it's probably wrong.

Question 10

1. Hurricane Mira, because its lower category causes more concentrated wind damage instead
2. Hurricane Mira, because slightly weaker winds always produce higher storm surges than stronger storms
3. Hurricane Nora, because its higher storm surge, linked to storm strength in Source A, suggests greater coastal flooding (correct answer)
4. Both storms will cause identical flooding since both fall into Category 3 wind speeds

Explanation: Whenever a question asks you to combine two sources, your job is to find the connection between them: use a fact from one source to interpret the data in the other. Here, Source A gives you a rule ("Higher categories also usually bring more dangerous storm surge flooding"), and Source B gives you the specific numbers for each storm. Look at the storm surge forecasts in Source B: Hurricane Nora has a 9-foot surge, while Hurricane Mira has only a 5-foot surge. Since coastal flooding comes from storm surge, and Nora's surge is much higher, Nora is the storm more likely to cause serious coastal flooding. That's why Hurricane Nora, because its higher storm surge, linked to storm strength in Source A, suggests greater coastal flooding is correct—it uses both sources together. The choice claiming Hurricane Mira causes more concentrated wind damage is wrong because the question asks about flooding, not wind damage, and Mira actually has the lower surge. The option saying weaker winds always produce higher surges is false—Source A tells you the opposite, that stronger storms usually bring bigger surges. And the claim that both storms cause identical flooding since both are Category 3 ignores the clear difference in their surge numbers (9 feet vs. 5 feet); same category does not mean same flooding. When a question says "based on both sources," always ask yourself: which fact from one source helps me interpret the numbers in the other? And read carefully for the exact topic—here, "flooding" points you to storm surge, not wind speed.

Question 11

1. It is recycled successfully because 6th grade had the highest participation rate of the three grades listed
2. It is sent to the landfill because 6th grade's contamination rate is above the stated threshold (correct answer)
3. It is recycled successfully because its contamination rate stays below the twenty percent cutoff
4. It is sent to the landfill because 6th grade had a lower participation rate than the other grades

Explanation: To answer this, you have to pull the rule from one source and a number from the other. Source B gives the rule: contamination above 20% means the whole bin goes to the landfill. Source B also lists the 6th grade contamination rate at 40%. Since 40% is above 20%, most of the 6th grade recycling ends up in the landfill. That's why the correct answer connects the contamination rate to the threshold. The choice saying it is recycled because participation was highest uses the wrong number. Participation (90%) sounds impressive, but the rule depends on contamination, not on how many people took part. The choice saying it is recycled because contamination stays below the cutoff misreads the data—6th grade's 40% is well above 20%, not below it. The choice saying it goes to the landfill because participation was lower reaches the right outcome for the wrong reason: 6th grade actually had the highest participation, and participation doesn't decide the outcome anyway. Only the contamination rate compared to the threshold explains what happens.

Question 12

1. They block out most of the harmful radiation astronauts face during the journey, keeping the crew safer along the way
2. They carry more fuel and supplies, letting astronauts stay longer on Mars once they arrive at the planet
3. They shorten travel time, which lowers radiation exposure and cancer risk for astronauts on the way to Mars (correct answer)
4. They make the trip smoother and more comfortable, which helps astronauts avoid the health problems of long flights

Explanation: Both sources point to the same main benefit: the nuclear thermal engine makes the trip to Mars faster—dropping it from seven months to four—and that shorter travel time means less time exposed to dangerous radiation. Source A says the engines reduce 'how long astronauts face dangerous radiation' and lower 'cancer risk,' while Source B explains that 'every extra week adds to an astronaut's total radiation dose.' So the correct answer connects shorter travel time to lower radiation and cancer risk—the idea both texts share. The choice about blocking out harmful radiation is wrong because neither source says the engines shield or block radiation; they cut exposure only by making the trip shorter, not by protecting the crew during it. The choice about carrying more fuel and supplies to stay longer on Mars invents a benefit neither source mentions—both focus only on speed and radiation, not cargo or time spent on the planet. The choice about a smoother, more comfortable trip also adds an idea not found in either source. Neither text discusses comfort; the health benefit they describe comes from reduced radiation, not from a gentler ride. When a question asks what 'both sources' agree on, check each answer against each text. If an idea appears in only one source, or in neither, it can't be the shared main benefit.
