Identify the tone of the Irish poem below:What is this love, - this love that makesMy heart's warm pulses quiver?They say it is the power that wakesThe hyacinth 'mid hazel brakes,The lilies by the river,And that same thing that bids the doveSit in the pine-tree high above,Its sweetheart wooing;But oh! alas! wate'er it be,It comes for my undoing! The lily of the river sideBy its sweet mate reposesThrough autumn moons and winter-tide,To wake in love and beauty's prideWhen comes the time of roses;And in the springing of the yearThe doves' sweet voices you will hearTheir vows renewing;But oh! alas! whate'er love be,And howsoe'er it comes to me,It comes for my undoing! a.lightheartedc.concernb.seriousd.grief
