Passage:

In the southern canals of Mexico City, the ancient agricultural system of *chinampas*—artificial islands created by the Aztecs—is experiencing a modern renaissance. Once the primary source of food for the pre-Hispanic valley, these 'floating gardens' have faced decades of degradation due to urban sprawl, water pollution, and the introduction of invasive species. However, a collaborative initiative involving local farmers, biologists, and urban planning institutions is working to revitalize this ecological heritage. By integrating traditional farming techniques with modern water filtration systems, project organizers have successfully restored soil quality and re-established native crop production in select canals. Beyond preserving cultural heritage, the project aims to establish a self-sustaining local food supply, reducing the city's reliance on long-distance agricultural imports. Critics argue that the scale of the restoration is too small to make a significant impact on Mexico City's vast food demands. Nonetheless, proponents emphasize that the *chinampas* serve as an invaluable, scalable model for climate-resilient urban agriculture, demonstrating that ancestral knowledge can offer practical solutions to contemporary resource crises.

Read the following protocol for a research facility:

Protocol for Accessing the Advanced Biomaterials Laboratory:
All researchers must obtain level-3 clearance prior to entering the facility. While it is strongly suggested that personnel wear double-layered nitrile gloves, standard latex gloves are mandatory at all times. In the event of a minor chemical spill, researchers should immediately notify the floor supervisor, although filing a formal incident report is only required if the spill exceeds 50 milliliters. For spills under this threshold, documenting the event in the shift log is highly recommended to maintain protocol transparency. Furthermore, before leaving the laboratory, it is incumbent upon all staff to sanitize their workstations, and they are encouraged to run the automated self-cleaning cycle on the fume hoods if the daily usage exceeded four hours.

Based on the laboratory protocol, which of the following scenarios describes a researcher who has failed to fulfill a mandatory obligation, as opposed to someone who has merely declined a recommended action?

Read the following literary passage:

'For three decades, Don Celso watched the construction of the grand railway that was promised to connect his valley to the capital. Every afternoon, he sat on his porch, listening to the distant, rhythmic clanging of iron against stone, a sound that became the very heartbeat of the village. The politicians had spoken of infinite horizons, of mineral wealth flowing out, and of modernity flowing in. Yet, as the years dissolved, the tracks remained incomplete, terminating abruptly at the edge of the great ravine, a rusted iron claw reaching into empty air. The workers eventually departed, leaving behind skeleton cabins and mountains of gravel that the tropical rains slowly flattened back into the earth. The villagers, once animated by the fever of anticipation, returned to their ancestral crops, their conversations no longer touched by the word "tomorrow." Don Celso, now silver-haired, realized that the railway had indeed changed them, not by delivering them to a grander world, but by anchoring them more deeply in the static present. The half-built track stood not as a path to progress, but as a monument to the illusion of departure, proving that their isolation was not a geographical circumstance, but a destiny they had long accepted.'

Read the following promotional flyer for an urban forestry project and answer the question:

Cerros Verdes: The Valparaíso Urban Reforestation Project
Valparaíso is renowned for its vibrant, colorful hills, but recent fires and rapid urban expansion have severely depleted our native forests. The 'Cerros Verdes' project, sponsored by the Municipal Environmental Alliance, is dedicated to restoring these vital ecosystems. This year, our focus is on Cerro Panteón, where we aim to establish a protective green belt of drought-resistant native trees like peumos and boldos.

On Saturday, October 10, 2026, we are hosting our largest planting drive yet. The alliance has already secured funding for 1,000 saplings through corporate sponsorships; however, executing a project of this scale requires hands-on community action. We are looking for individuals and local organizations to join us as active planters. While financial contributions to our seedling maintenance fund are welcome, our urgent priority is physical participation on planting day.

Participants will receive training, tools, and a commemorative t-shirt. To ensure we have sufficient equipment and can coordinate transportation to the planting sites, all prospective volunteers must complete the registration form on our portal by October 5. Your hands-on involvement is the key to rebuilding Valparaíso’s natural heritage.

Read the following literary passage:

"In the narrow backroom of Don Mateo’s workshop, hundreds of antique pendulums swung in relentless, unsynchronized rhythms. Outside, a dense gray fog pressed heavily against the leaded windowpanes, blurring the cobblestones and swallowing the daylight into a perpetual twilight. The air inside smelled of cold brass, stagnant oil, and aging parchment. Each mechanical strike and hollow chime did not mark the lively passage of moments, but rather counted down an inescapable erosion of time. Don Mateo remained motionless over his workbench, his magnifying loupe reflecting only the dull gleam of motionless gears. The surrounding wall of ticking clocks felt less like a sanctuary of craftsmanship and more like an echo chamber of impending decay."

Read the following passage from a journalistic article concerning energy initiatives in Chile:

"In the heart of Chile’s Atacama Desert, the Cerro Dominador solar thermal plant stands as a milestone, utilizing 10,600 mirrors to direct solar radiation toward a central tower. According to energy ministry records, the facility generates 110 megawatts of clean energy, enough to power over 380,000 homes annually. Proponents argue that this project represents the only viable path forward for Chile's transition to green energy, claiming it is the most beautiful engineering feat in South America. While the plant has successfully reduced carbon dioxide emissions by 640,000 tons per year, local environmental groups express concern that the intensive cleaning of the mirrors could strain the region’s scarce water resources. Nevertheless, the government planning commission insists that the long-term ecological benefits far outweigh any temporary localized water disruptions."

Based on the passage, which of the following statements represents a subjective opinion rather than a verifiable fact?

Read the following instructions for preparing a natural indigo dye vat:

To prepare a natural indigo dye vat, follow these steps:
Initially, heat the water in the vat to exactly $50^\circ\text{C}$ to ensure the indigo powder disperses evenly. Previously, the indigo must be thoroughly ground into a fine paste with a small quantity of warm water. Prior to introducing the reducing agent, dissolve the alkaline agent (hydrated lime) and stir the solution gently in a single direction to avoid incorporating oxygen. Subsequently, once the pH stabilizes at $11$, add the sodium hydrosulfite. Let the vat rest undisturbed for $45$ minutes. Finally, once the liquid beneath the surface bronze skin turns a clear amber-yellow, the first fabric immersion can begin.

Based on the instructions, which action must be performed immediately before adding the sodium hydrosulfite?

Read the following literary passage:

'The cold of the high páramo did not merely seep through the cracks of the wooden shutters; it settled in the bones of the old house like an unwelcome guest that had no intention of leaving. Outside, the mist clung to the jagged peaks of the Andes, swallowing the stunted pajonal grass and turning the horizon into a uniform shroud of white. Inside, Clara watched the solitary candle flame flicker against the damp stone walls. Every creak of the floorboards echoed through the empty rooms, a reminder of the silence that had reigned since the harvest failed. She wrapped her woolen shawl tighter around her shoulders, staring at the door. The wind howown through the canyons, carrying the distant, hollow sound of sheep bells, but no footsteps followed. She knew the road down to the valley was already blocked by the mudslides, yet she kept the candle lit, its feeble light a stubborn defiance against the encroaching darkness of the mountain night.'

Read the following English translation of an excerpt from a contemporary short story set in Valparaíso, Chile:

For decades, Ernesto walked the steep, winding staircases of Cerro Alegre, dragging his heavy wooden organillo. While the cylinder inside cranked out old European waltzes, the children dancing on the cobblestones and the neighbors leaning from their balconies heard something entirely local: the collective heartbeat of their hills. Ernesto knew the instrument was slowly dying; its bellows leaked air with a faint sigh, and the salt wind from the Pacific had rasped its pipes. Yet, he resisted replacing it. To him, the organillo was not merely a generator of sound, but a repository of the city's history. Each creak of the wood recalled those who had once danced to its tune but had since drifted away. The music bridged the past and the present, tying the ephemeral life of the port to a permanent, shared memory.

Read the following guidelines for the Municipal Urban Garden Cooperative Program:

"To secure a plot in the Municipal Urban Garden Cooperative for the upcoming season, applicants must complete several mandatory steps. First, all prospective gardeners are required to submit an online registration form and verify their municipal residency by uploading a utility bill from the last three months. Once residency is confirmed, applicants must attend a two-hour workshop on organic farming practices and water conservation, which is offered on the first and second Saturdays of next month. Following the workshop, a non-refundable safety deposit of $25 must be paid to the municipal treasury within five business days to finalize the reservation. Failure to complete the payment within this timeframe will result in the immediate forfeiture of the assigned plot to the next person on the waiting list. Note that returning gardeners who maintained a plot in the previous consecutive year are exempt from the training workshop requirement, but they must still submit the residency verification and pay the safety deposit by the specified deadline. It is highly recommended, though not required, that all participants join the cooperative's monthly planning meetings."

According to the guidelines, which of the following is a mandatory action that a returning gardener must take to secure their plot?
