Read the lines from "song vii"  by rabindranath tagore. ornaments would mar our union; they would come between thee and me; which phrase best illustrates the musical quality of the lyric poem? “ornaments would”“our union”“thee and me”“come between”

The union that Tagore talking about could refer to divine being. Indeed, his other poems from the same collection is rich with religious references. Ornaments stands between them and they are actually jinglings (the word is given in the next line of the poem) which is a sound or music. However, the pattern and repetition exists between the words thee and me which gives the poem a musical tone. The correct answer is "thee and me".

type of error:

the error in the sentence is a "dangling modifier". a dangling modifier is a phrase, word or clause that "dangles" because there is not target to modify. in this case, "after mopping the floor" is the dangling modifier since it has no word to modify. the noun "house" cannot mop the floor; therefore there is a mistake in the writing of the sentence.
