TOEIC Part 7 always includes at least two email or memo passages. The questions test whether you understood the purpose, the key detail, and the implied action. French speakers read too literally — you need to read for intent, not just content.
inquire about (se renseigner sur), enclosed / attached (ci-joint), at your earliest convenience (dès que possible), regarding (concernant), be advised that (veuillez noter que), further to (suite à).
Don't read the full email first. Read the questions, identify the keywords, then scan the email for those keywords. TOEIC emails are designed to waste your time if you read top-to-bottom.
French speakers often choose the answer that restates information from the email without answering the question. If the question asks "Why did Mr. Lee write?" — the answer is the purpose (to request, to inform, to complain), not a detail from the middle of the email.
