Question 34

It is 8 a.m., and the site manager is stating a requirement that is in force now for today's archaeological dig. Select all that apply: which notices correctly express that stated present obligation?

  1. Researchers must label every soil bag before lunch today.Bonne réponse
  2. Researchers have to label every soil bag before lunch today.Bonne réponse
  3. Researchers must to label every soil bag before lunch today.
  4. Researchers had to label every soil bag before lunch today.

Explication

Must label and have to label are both standard ways to express the requirement currently in force for work later today. Must to label is malformed because must takes a bare verb, while had to label places the obligation in the past and conflicts with the stated present frame.
