Answer

Brief Explanations:

  1. Based on general knowledge of early - metal detector problems, being too expensive is not a typical early - problem compared to size, functionality, and safety concerns.
  2. Analyzing the second - paragraph content to determine its main idea.
  3. Considering the function of metal detectors in clothing production to ensure safety.
  4. Knowing the historical first - use of metal detectors for miners.
  5. Thinking about common places where metal detectors are used and eliminating options.
  6. Understanding the role of metal detectors for soldiers in detecting hidden threats.
  7. Recognizing the main reason people use metal detectors at the beach is to find valuable items.
  8. Understanding the working sequence of metal detectors starting from creating magnetic waves.
  9. Considering the general improvements of metal detectors over time including cost, weight, and performance.
  10. Summarizing the overall content of the text which is about what metal detectors do and how they are used.
