Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. must.
Context: “Instead of being enraged over circumstances beyond their control, drivers (3)________ learn to be patient.”
Explanation:
The sentence suggests a strong recommendation or necessity.
must = expresses obligation or necessity.
Meaning of the options:
must: shows strong necessity or obligation. (correct)
ought: usually followed by to (“ought to learn”), so incorrect here alone.
can: indicates ability, not necessity (less strong).
to: incorrect alone without verb.
Final sentence: drivers must learn to be patient.
Hence, the chosen option is correct.
