Passage A
The sirens in Olympus Base howled, a sound that meant only one thing: hull breach. Dr. Aris Thorne, the chief engineer of the Mars colony, stared at the diagnostic screen. Sector 4, the primary hydroponics bay, was losing pressure at a catastrophic rate. If not sealed within three minutes, the entire colony's oxygen supply would bleed into the Martian atmosphere.
Thorne faced an agonizing choice. Protocol dictated an immediate lockdown of Sector 4, which would seal the breach but trap two botanists inside, condemning them to the vacuum. Alternatively, he could override the automated bulkheads, giving the botanists a 90-second window to escape, but risking a cascading pressure failure that could suffocate all 140 colonists. The AI system, ALICE, coldly calculated a 94% probability of colony-wide extinction if the override was engaged.
Sweat stinging his eyes, Thorne initiated the override. He then diverted power from the life-support reserves to create a localized pressure bubble around the airlock. It was a theoretical maneuver, never tested under live conditions. As the countdown ticked past 60 seconds, the base shuddered. The pressure bubble held just long enough for the botanists to scramble through. Thorne slammed the lockdown button, sealing the sector just as the bubble collapsed. The colony survived, but Thorne knew the inquiry into his violation of protocol would be ruthless.

Passage B
The descent of the Mariana Explorer into the Challenger Deep was flawless until the 9,000-meter mark. Then, a sudden, violent acoustic shockwave severed the umbilical cable connecting the submersible to the surface ship. Inside the cramped titanium sphere, Captain Elena Rostova and systems analyst David Chen were plunged into absolute darkness and silence. The primary power grid was dead.
Rostova’s training kicked in. She manually activated the emergency battery, bathing the cabin in a dim red glow. Chen frantically checked the life-support readouts. They had 72 hours of oxygen, provided they remained calm. However, the acoustic shock had also damaged the CO2 scrubbers. Carbon dioxide levels were rising faster than anticipated, cutting their survival window to less than 18 hours.
Their only hope was to manually release the ballast weights to initiate an emergency ascent. But the electronic release mechanism was fried. Chen proposed a risky EVA (Extravehicular Activity) using the sub's robotic arm to physically dislodge the weights. It required bypassing the sub's safety protocols and hot-wiring the arm's control board using the remaining battery power. One mistake would short-circuit the entire sub, leaving them to suffocate in the abyss. With the air growing thick and their minds fogging from CO2 buildup, Rostova gave the order to proceed.
6. What caused the crisis for the Mariana Explorer?
A. A collision with an unknown sea creature.B. A sudden acoustic shockwave that cut their cable.C. An explosion in the primary power grid.D. A failure of the titanium sphere's structural integrity.
7. Why did their survival window decrease from 72 hours to 18 hours?
A. The emergency battery was rapidly draining.B. The oxygen tanks were leaking into the ocean.C. The CO2 scrubbers were damaged, causing a fast buildup of carbon dioxide.D. The surface ship stopped sending oxygen.
8. What was Chen's plan to save the submersible?
A. To repair the umbilical cable using the robotic arm.B. To wait for a rescue team from the surface.C. To fix the CO2 scrubbers with spare parts.D. To use the robotic arm to manually drop the ballast weights.
9. What was the main risk of Chen's proposed plan?

Passage C
Antarctica’s Vostok Station is the most isolated human outpost on Earth. When Dr. Sarah Jenkins noticed three researchers exhibiting violent coughing fits and high fevers, she initially suspected a severe strain of influenza. However, blood tests revealed something terrifying: a prehistoric pathogen, thawed from deep ice core samples, was spreading through the station.
With winter setting in, evacuation was impossible. The station was cut off from the world for the next six months. Jenkins implemented a draconian quarantine protocol. The station was divided into "clean" and "hot" zones, separated by heavy plastic sheeting and UV air filters. Anyone showing symptoms was immediately moved to the hot zone.
The psychological toll was immense. Paranoia ran rampant among the healthy crew, while those in the hot zone felt abandoned. Supplies of broad-spectrum antivirals were dwindling. Jenkins realized that the only way to stop the spread was to intentionally lower the ambient temperature in the hot zone, slowing the virus's replication but risking hypothermia for the infected. It was a brutal triage decision. She had to balance the survival of the uninfected against the suffering of the sick.
11. What was the source of the pathogen at Vostok Station?
A. A sick penguin brought into the station.B. A prehistoric virus released from deep ice core samples.C. A contaminated food supply from a recent airdrop.D. A mutated flu virus brought by a new researcher.
12. Why couldn't the sick researchers be evacuated?
A. The surface ship was destroyed by an iceberg.B. The harsh Antarctic winter made travel impossible.C. The government ordered them to stay to study the virus.D. They refused to leave their research behind.
13. What does the word "draconian" in Paragraph 2 suggest about the quarantine protocol?
A. It was extremely harsh and severe.B. It was highly advanced and technological.C. It was ineffective and poorly planned.D. It was gentle and accommodating.
14. What difficult decision did Dr. Jenkins have to make?
A. To stop feeding the infected researchers to save food.B. To test unproven vaccines on the healthy crew.C. To lower the temperature in the hot zone to slow the virus, risking hypothermia.D. To abandon the station and walk to the nearest base.
15. The passage primarily focuses on:
A. The discovery of ancient viruses in Antarctica.B. The psychological effects of isolation on scientists.C. A medical emergency and the extreme measures taken to contain it.D. The daily routine of researchers at Vostok Station.
Passage D
The Carrington Event of 1859 was a mere spark compared to the Coronal Mass Ejection (CME) that struck Earth in 2026. The super-storm overloaded the global electrical grid in seconds. Transformers exploded in showers of sparks, satellites were blinded, and the digital world instantly went dark. In the heart of New York City, the blackout trapped millions in skyscrapers, subways, and elevators.
Marcus Vance, an emergency management coordinator, found himself in a subterranean command center running on failing backup generators. His task was monumental: coordinate the evacuation of hospitals and maintain civil order without communication networks. The immediate crisis was water. Without electricity, the city's water pumps stopped. Within 48 hours, desperation would turn to violence.
Vance authorized the deployment of the National Guard to secure the reservoirs, but getting the water to the citizens required a low-tech solution. He organized "bucket brigades" utilizing the city's abandoned subway tunnels, moving water manually from the outskirts into Manhattan. It was a desperate, exhausting effort, relying purely on human endurance and solidarity in the face of absolute systemic collapse. The storm proved that humanity's reliance on technology was its greatest vulnerability.
16. How did the 2026 CME compare to the Carrington Event?
A. It was much less severe.B. It only affected satellites, not the electrical grid.C. It was significantly more powerful and destructive.D. It happened exactly the same way.
17. What was the most immediate and critical crisis in New York City after the blackout?
A. A lack of food supplies in supermarkets.B. The failure of the city's water pumping system.C. The crash of the stock market.D. The spread of diseases in the subways.
18. How did Vance solve the problem of water distribution?
A. By repairing the electrical water pumps with backup generators.B. By flying in water using military helicopters.C. By organizing manual "bucket brigades" through the subway tunnels.D. By waiting for the rain to fill the city's backup tanks.
19. What is the underlying theme of the passage?
A. The superiority of modern technology over nature.B. The extreme vulnerability of modern society due to its dependence on electricity.C. The efficiency of the National Guard in urban warfare.D. The safety of subterranean command centers during solar storms.
20. What does the phrase "systemic collapse" in the final paragraph refer to?
A. The destruction of the subway tunnels.B. The failure of the entire technological and infrastructural network.C. The emotional breakdown of Marcus Vance.D. The collapse of the skyscrapers in New York City.
