Choose the best words to help this anxious college student polish their formal email to the department head.
Dear Dr. Smith, with _________________________ I spoke yesterday regarding the laboratory incident:
I am writing to defend my lab partner, _________________________ dedication to studying glowing frogs is unmatched in this university.
I have attached the security footage showing the exact moment _________________________ the frogs managed to escape their enclosures. We apologize for the glowing hallways.

The correct answers are:

  • whom
  • whose
  • when

Whom is used after the preposition "with" in formal writing.

Whose shows possession, meaning "the dedication of my lab partner".

When modifies a noun of time, such as "the exact moment".
