  "schemaVersion": 1,
  "id": "network-throughput-numeric-input-example",
  "title": "Network Throughput Numeric Example",
  "description": "A canonical numeric-input example that uses an explicit tolerance so contributors can see how rounded answers are handled.",

  "questions": [
    {
      "id": "megabits-to-megabytes",
      "title": "A connection is rated at 100 megabits per second. About how many megabytes per second is that before overhead?",
      "description": "Type a number only. Small rounding differences should still count as correct.",

        "mode": "numeric",
        "acceptedAnswers": [12.5],
        "tolerance": 0.2
      },
      "explanation": "There are 8 bits in a byte, so dividing 100 megabits by 8 gives 12.5 megabytes per second. The tolerance shows how to accept rounded answers such as 12.4 or 12.6 when the teaching goal is the unit conversion rather than strict formatting.",

  "description": "A canonical text-input example. Text mode is case-insensitive, trimmed, and whitespace-collapsed by default, so the minimal validation object needs no flags at all.",

        "acceptedAnswers": ["first conditional", "the first conditional"]
      },
      "explanation": "This sentence describes a real future possibility, which is why it is called the first conditional. Text mode is forgiving by default, so learners may type extra spaces or different capitalization without changing the result.",

      "explanation": "In the simplified hierarchy, the processor checks L1 first and then L2. It reaches main memory only if the requested data is absent from both cache levels.
