Three cover letter openings

The first paragraph is the only one they are guaranteed to read.

Write three opening paragraphs for this cover letter, each taking a different angle on why I am writing to them specifically. Use only facts from my notes. Banned: "I am writing to apply", "I was excited to see", passionate. Then say which you would send and which would be a mistake.
