Cawnpore, Ahmedabad (his ashram), Calcutta, Patna, Muzaffarpur

Gandhi visited all these places in sequence: first he had appointments in Cawnpore, then returned to his ashram near Ahmedabad, then met Shukla in Calcutta, went to Patna, and finally to Muzaffarpur before reaching Champaran. Delhi is not mentioned in his journey.

True

The text mentions that the servants at Rajendra Prasad's house took Gandhi to be another peasant like Shukla. They even didn't allow him to draw water from the well, thinking he might be an untouchable.

They should stop going to law courts as it does little good

Gandhi told the lawyers that they should stop going to law courts because where peasants are so crushed and fear-stricken, law courts are useless. The real relief for them is to be free from fear.

Gathering facts through investigation, Civil disobedience, Non-violent protest, Organizing peasants

Gandhi used systematic fact-finding, civil disobedience (refusing to leave Champaran), non-violent methods, and organized the peasants. He never used or advocated violence, which goes against his principles of satyagraha.
