Lesson Overview & Key Takeaways

  • Story Summary: In the town of Allen, Argentine Patagonia, families on Calle Ciega 10 say cancers, pregnancy losses and congenital defects have surged since drilling began roughly 13 years ago. Vaca Muerta holds the world's second-largest shale gas reserve and fourth-largest shale oil reserve, with more than 2,600 active wells now operating across the region.
  • CEFR Target: Level C2 (Mastery) — calibrated for clear sentence structure and targeted reading fluency.
  • Core Vocabulary: fiercely contested, congenital disabilities, hydraulic fracturing, unconventional, coinciding with.
  • Skills Practised: Reading comprehension, dual-accent listening, and contextual grammar.

100%
More than 2,600 active wells tap the Vaca Muerta formation in Argentine Patagonia, the world's second-largest shale gas reserve and fourth-largest shale oil reserve, yet the human cost of that extraction remains by those who live beside it.
Residents of Calle Ciega 10 in the town of Allen trace a dramatic rise in illnesses—cancers, pregnancy losses—back roughly thirteen years, the onset of nearby drilling operations. The Saldías family alone recount a son born with three lungs in 2020, a daughter severe skin patches in 2019, and stroke-like symptoms during a pregnancy in 2023.
Scientific research has connected to respiratory and skin problems, cancer, and complications in pregnancy among nearby residents. Mapuche communities including the Nawel family in the Zonal Xawvn Ko confederation and the Añelo Lof Campo Maripe community report high rates of miscarriage, respiratory disorders, skin ailments, and several cancer cases, while also noting deformed or stillborn livestock.
The government of Cristina Kirchner introduced shale extraction to the area in 2012, and the current administration under Javier Milei depends on those resources for economic recovery while welcoming foreign investment for hydrocarbon production and export. By late 2025, Argentina recorded an all-time production high, with petroleum surpassing soya bean meal for the first time as the country's top export product.
According to the NGO OpSur, YPF manages thirty-three percent of the gas and thirty-nine percent of the oil in the region, with remaining output belonging to companies such as Chevron, TotalEnergies, and Shell.

Passage

More than 2,600 active wells tap the Vaca Muerta formation in Argentine Patagonia, the world's second-largest shale gas reserve and fourth-largest shale oil reserve, yet the human cost of that extraction remains fiercely contested by those who live beside it. Residents of Calle Ciega 10 in the town of Allen trace a dramatic rise in illnesses—cancers, pregnancy losses—back roughly thirteen years, coinciding with the onset of nearby drilling operations. The Saldías family alone recount a son born with three lungs in 2020, a daughter afflicted by severe skin patches in 2019, and stroke-like symptoms during a pregnancy in 2023. Scientific research has connected hydraulic fracturing to respiratory and skin problems, cancer, congenital disabilities, and complications in pregnancy among nearby residents. Mapuche communities including the Nawel family in the Zonal Xawvn Ko confederation and the Añelo Lof Campo Maripe community report high rates of miscarriage, respiratory disorders, skin ailments, and several cancer cases, while also noting deformed or stillborn livestock. The government of Cristina Kirchner introduced shale extraction to the area in 2012, and the current administration under Javier Milei depends on those resources for economic recovery while welcoming foreign investment for hydrocarbon production and export. By late 2025, Argentina recorded an all-time production high, with petroleum surpassing soya bean meal for the first time as the country's top export product. According to the NGO OpSur, YPF manages thirty-three percent of the unconventional gas and thirty-nine percent of the unconventional oil in the region, with remaining output belonging to companies such as Chevron, TotalEnergies, and Shell.

1. What rhetorical function does the word 'yet' serve in the opening sentence?
2. Why does the author use the verb 'trace' rather than 'attribute' when describing how residents link their illnesses to drilling?
3. Which of the following best characterises the relationship between the fourth paragraph (government policy and production) and the second and third paragraphs (health effects)?

Editorial Discussion & Reflection

Spoken & Written Reasoning

Formulate your opinion on these real-world questions. Take brief notes or practice answering out loud.

1. The text uses 'coinciding with' rather than 'caused by' when describing residents' illnesses relative to drilling. Is this distinction journalistically necessary, or does it subtly weaken the communities' position?
2. Argentina's government depends on unconventional hydrocarbons for economic recovery while scientific research links hydraulic fracturing to serious health outcomes. In your view, should economic necessity ever justify accepting what residents describe as a 'fiercely contested' human cost?
3. The article presents anecdotal family accounts (the Saldías, Nawel) alongside institutional data (OpSur, production figures). Which form of evidence carries more weight in public discourse, and why?
