Answer:
1. Rhetoric ⇒ Violent language
2. Armed man ⇒ Soldier
3. Non-cooperation ⇒ Boycott
4. Holiday makers ⇒ Rebel army
In this letter from Mr. J.B. Pennington to Mahatma Gandhi, he criticizes Gandhi's non-cooperation with the Indian government which Gandhi had called a boycott and he also talks about Gandhi's criticism of General Dyer who called unarmed men and women a rebel army and dismisses this as mere rhetoric which to him was violent language without proof.
