You need to create a regular expression pattern that matches EXACTLY these items in the text:
[
  "2023-11-15",
  "11/16/2023",
  "Nov 17, 2023",
  "2023.11.18",
  "19 Nov 2023",
  "+1-555-123-4567",
  "555.987.6543",
  "(555) 246-8080 ext. 123",
  "ABC123XYZ",
  "DEF456UVW-2023",
  "GHI789JKL_01",
  "test@example.com",
  "another.email@sub.domain.co.uk",
  "third_email+extra@domain.info",
  "1-800-FLOWERS"
]

Rules:
1. Your regex must match ALL of the target items in the text.
2. Your regex must NOT match anything else in the text.
3. The pattern should be a valid JavaScript regular expression.
4. Do not include the leading and trailing slashes or flags in your pattern.

You'll use the "make_move" function to submit your solution with:
1. reasoning: Your reasoning for this regex pattern
2. move: The regex pattern as a simple string

Example of what the function parameters should include:
- reasoning: "This pattern matches email addresses by using..."
- move: "[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}"

IMPORTANT:
- The regex pattern should be a simple string.
- Do NOT use raw regex notation with slashes like /pattern/.
- Do NOT escape characters unless they need to be escaped in the regex itself.
- For example, to match parentheses, use "\(\)" not "\\(\\)".
- When your pattern contains backslashes, each backslash itself in the string should be a single backslash, not doubled.

Think carefully and test your pattern mentally before submitting.
