Science and Technology

Science and Technology passages deal with topics related to discoveries, inventions, research, and advancements in fields like physics, biology, medicine, computers, engineering, and space. They often explain how something works, evaluate its impact on society, or discuss future possibilities. These passages are usually factual and logical, but may also contain critical or ethical perspectives.

Key Features of Science and Technology Passages

  • Technical Explanations: Often include definitions, processes, or mechanisms.
  • Use of Data/Examples: Facts, experiments, and real-world applications support ideas.
  • Neutral to Analytical Tone: Typically objective, though sometimes mixed with evaluation or caution.
  • Focus on Progress/Impact: Explains both benefits and drawbacks of innovations.
  • Jargon Use: May contain technical terms, but context usually clarifies meaning.

How to Approach Science and Technology Passages

  1. Identify the central concept: Understand whether it’s about discovery, process, or impact.
  2. Don’t get stuck on jargon: Focus on overall meaning instead of memorizing technical terms.
  3. Track cause-effect links: Many passages explain why/how something happens.
  4. Note implications: Future applications or ethical debates may be part of the passage.

Conceptual Tips and Common Mistakes

  • Avoid overcomplicating: Even complex terms usually aren’t central to exam questions.
  • Distinguish fact vs opinion: Facts describe findings, opinions predict or evaluate.
  • Look for comparisons: Many passages compare old vs new technology.
  • Be wary of bias: Some texts highlight benefits but understate risks.
