Read this excerpt from “Rikki-Tikki-Tavi” by Rudyard Kipling. Teddy shouted to the house: “Oh, look here! Our mongoose is killing a snake”; and Rikki-tikki heard a scream from Teddy's mother. His father ran out with a stick, but by the time he came up, Karait had lunged out once too far, and Rikki-tikki had sprung, jumped on the snake's back, dropped his head far between his fore-legs, bitten as high up the back as he could get hold, and rolled away. Who would be the best primary source to interview about what it was like to watch the fight between Rikki-tikki-tavi and Karait? A. an animal expert B. Teddy C. Karait D. Rikki-tikki-tavi
