Set 3: Cross-Text Connections (Intermediate)
Explanation
PASSAGE
Text 1 The search for extraterrestrial intelligence (SETI) focuses on detecting radio signals from other civilizations. Proponents argue that radio waves are the most efficient way to communicate across interstellar distances. Text 2 Critics argue that an alien civilization might use a technology we haven't discovered yet, or one we stopped using, like lasers. Relying solely on radio waves might be like trying to detect a smartphone signal with a telegraph.
Which choice best describes the limitation of SETI presented in Text 2?
Detailed Answer Explanation
This question asks you to compare perspectives from two passages. Text 1: Use radio. Text 2: Aliens might use different tech (lasers, or unknown). Limitation: Anthropocentric assumption (Telegraph analogy). 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:
• "technology we haven't discovered"
• "like trying to detect ... with a telegraph"
Why others are wrong: A (Assumes they do.), C (Not mentioned.), D (They can.).
