Given levels: A1, A2, B1, B2 and C1. Which cefr level would you assign to: "The Rainbow comes and goes,

And lovely is the Rose,

The Moon doth with delight

Look round her when the heavens are bare,

Waters on a starry night

Are beautiful and fair;

The sunshine is a glorious birth;

But yet I know, where'er I go,

That there hath past away a glory from the earth."?
