Wrong!
"must have been" is correct because the broken alarm is inferred from the fact that no alert sounded.
11The objection that the deadline is unrealistic ............... that the legal review cannot be completed in three days.
Wrong!
"assumes" is correct because the clause describes what the objection depends on, not what it establishes with evidence.
