Set 7: Cross-Text Connections (Intermediate)
Explanation
PASSAGE
Text 1 Cryptocurrency relies on blockchain technology, a decentralized ledger. To validate transactions, computers solve complex puzzles in a process called 'mining,' which secures the network. Text 2 Proof-of-Work mining is incredibly energy-intensive. The Bitcoin network consumes more electricity annually than some entire countries. This environmental cost has led to the development of 'Proof-of-Stake' alternatives.
What problem with the mechanism in Text 1 drives the innovation described in Text 2?
Detailed Answer Explanation
This question asks you to compare perspectives from two passages. Text 1: Mining secures. Text 2: Energy intensive/Cost -> Proof-of-Stake. Driver: Energy consumption. Understanding how the authors relate to each other's views is essential. Identify whether they agree, disagree, or address different aspects of the topic. Focus on their specific claims and conclusions. When comparing texts, first identify each author's thesis or main argument. Then determine how these positions interact: do they complement each other, contradict each other, or address different aspects of the same issue? The relationship between texts reveals deeper meaning.
Key Evidence:
• "incredibly energy-intensive"
• "environmental cost"
Why others are wrong: D (Energy cost.), B (Complex puzzles.), C (Secures network.).
