What do you mean by "duck eggs" instead of "eggs"?

Because duck eggs are generally white and bigger than eggs, it is more appropriate to use zero to describe them.

Of course, generally speaking, a goose egg is bigger, but its skin is not as smooth as a duck egg.

So duck eggs are more suitable for describing zero than goose eggs.

Zero is a score that is easy to laugh at, and it is also an embarrassing score.

And the teacher was angry when he saw the score, so he had to find something to describe it.

Of course, it won't be a particularly beautiful thing. If eggs are used to describe it, it may be the most appropriate.

There are not many students who insult and belittle such scores, nor do they raise such students, but there is humor in it.

White means blank. If the student gets zero, it means that his answer is a blank sheet of paper, almost spotless.

Therefore, it is more appropriate to describe the color of duck eggs.

Moreover, the duck egg itself is smooth and the skin is particularly thin, and there is no such rough feeling. It should be more appropriate to describe it as round and zero.
