The challenge includes emails with special characters (plus signs, subdomains, hyphens), phone numbers in international and US formats (with optional parentheses, hyphens, country codes, and even an extension), dates in three distinct formats using dashes, slashes, and dots, as well as a mirrored ID that requires backreferences to ensure that the prefix and suffix match exactly. Distractor items are interwoven within the text (e.g., similar but invalid emails, phone numbers missing the required format, and date formats that should be ignored) to ensure that only the exact strings provided in the targetItems array are matched.
