- B.Callum forgets his assignment is due, but his parents don't get called.
- C.Callum goes out with friends and falls behind, but his parents don't get called.
- D.Callum forgets his assignment is due tomorrow but stays home to study.
Correct answer
Explanation
Step 1 — Map out the chain of events.
Rule 1: Forgets assignment → WILL go out (not study) (definite)
Rule 2: Goes out → MAY fall behind (not certain)
Rule 3: Falls behind → Teacher MIGHT call parents (not certain)
Step 2 — Find what is NOT POSSIBLE.
Rule 1 is definite: if Callum forgets his assignment is due, he WILL go out with friends instead of studying. This has no exceptions.
Option D says: "Callum forgets his assignment is due tomorrow but stays home to study."
This directly contradicts Rule 1. If he forgets, he WILL go out — he cannot forget AND stay home to study. That combination is impossible.
Answer: D — Callum forgets his assignment is due tomorrow but stays home to study (this is NOT possible)
