O stands for Opinion. Opinion is telling what your idea was about the topic. For an example: Littering is not good because it’s harmful for the environment.
R and E stands for Reason and Explanation. Reason is telling the reason why you thought about that. Explanation is explaining your reason. For an example: Some animals can’t tell if rubbish is food or not, if the animals eat rubbish it would kill them because it blocks their stomach.
O stands for Opinion. Opinion is telling what your idea was about the topic at the end. For an example: If littering continues, the environment would get worse.
