Reading Comprehension (Passage 1: Environmental Science & Ecology)
Read the passage carefully and answer questions 1 to 15:
Mangrove forests are among the most productive and biologically complex ecosystems on Earth. Thriving in the intertidal zones of tropical and subtropical sheltered coastlines, these salt-tolerant halophytes have evolved remarkable morphological and physiological adaptations to survive in harsh, saline, and waterlogged soils. Their dense, tangled root systems—often referred to as stilt roots or pneumatophores (breathing roots)—act as specialized conduits for gas exchange in oxygen-depleted anaerobic mud, while simultaneously functioning as natural breakwaters.
The ecological significance of mangroves extends far beyond their immediate perimeter. They serve as nurseries and breeding grounds for a vast array of marine species, including commercially vital fish, crabs, and molluscs. By trapping inland sediment and filtering terrestrial pollutants, mangrove roots prevent coastal erosion and preserve fragile coral reefs and seagrass beds located further offshore. Furthermore, mangroves are recognized as champions of “blue carbon” sequestration. They absorb and store atmospheric carbon dioxide in their biomass and deep sediment layers at rates three to five times higher per hectare than typical terrestrial upland forests.
Despite their critical utility in disaster risk reduction and climate change mitigation, mangroves face existential threats worldwide. Aquaculture expansion—particularly intensive shrimp farming—along with urban reclamation, deforestation for timber, and industrial pollution have caused the depletion of over one-third of the planet’s original mangrove cover. The preservation of regions like the Sundarbans, the world’s largest contiguous mangrove tract, requires comprehensive conservation frameworks integrating community-based coastal management, strict statutory protection, and scientific restoration of degraded mudflats.

Reading Comprehension (Passage 2: Technology, Ethics & Society)
Read the passage carefully and answer questions 16 to 30:
The accelerating integration of Artificial Intelligence (AI) into professional, creative, and administrative sectors has triggered an unprecedented paradigm shift in human society. Algorithmic systems, driven by neural networks and massive datasets, can now diagnose medical conditions with remarkable accuracy, optimize energy grids, analyze complex legal precedents, and compose coherent prose within seconds. Proponents argue that automation elevates productivity by liberating human workers from repetitive cognitive drudgery, paving the way for unprecedented innovation and economic prosperity.
However, the rapid deployment of autonomous technologies brings multifaceted ethical and socioeconomic dilemmas to the forefront. The potential displacement of both white-collar and blue-collar labor raises pressing concerns regarding systemic unemployment, socioeconomic stratification, and wealth centralization. Furthermore, generative algorithms routinely absorb and replicate cognitive biases embedded in their training data, perpetuating algorithmic discrimination in hiring algorithms, credit scoring, and predictive policing.
A critical dimension of this discourse centers on intellectual autonomy and epistemic integrity. Excessive reliance on synthetic content threatens to erode critical thinking, media literacy, and information authenticity in the public sphere. The ubiquity of deepfakes and algorithmic echo chambers complicates the discernment of empirical truth from sophisticated fabrication. To steer technological development toward human welfare, international regulatory bodies must institute robust governance frameworks that emphasize algorithmic transparency, rigorous data privacy, and mandatory human-in-the-loop oversight.
16. The transformative advancement in modern AI systems is primarily driven by:

Answer: (B) Relieving them from repetitive cognitive drudgery
18. According to the author, the displacement of labor due to automation could lead to:
(A) Universal economic equality
