It helps a researcher to better code the data and to find/organize illustrative examples of code pieces.
Answer:
Od is the right eye and Oi is the left eye.
When you ask for "what is object," we don't know since there is no reference , clues, image, instruction, or anything.
Explanation:
The O stands for Oculus (no not the toy lol), but for example, binoculars have the part "oculars" in it, which means "sight" or "vision." (Can be said to be the "root" of the word!)
The d in Od refers to dexter; latin for right, and i in Oi refers to sinister, which is left.
Sad and stingy probably would not work in this situation, but sly and mean are possibilities. Although either could be correct, I would go with sly, which means they are sneaky and conniving. I’m not a 100% sure, but I believe sly is the best answer. I hope this helps!
