Thinking tip (See first, then guess): Observation: “Riya is smiling.”, “There are crumbs on Kabir’s plate.”, “The plant’s leaves are yellow.” Inference: “Riya must be happy.”, “Kabir probably ate the biscuits.”, “The plant may need more water.” — words like must, probably and may. An inference can be wrong, so look for more clues before you are sure.
