The Movement in British poetry during the 1950s was a reaction against both modernism and the grandiosity of New Romanticism. The poets associated with The Movement advocated for a return to more traditional forms, clarity of expression, and a focus on everyday experiences.
In this context, let's analyze the magazines listed in the options:
Departure: This was a little magazine that aligned with The Movement, featuring poetry that rejected the obscurity of modernist and romantic traditions. It became associated with the poets of The Movement.
New Verse: This was a pre-World War II magazine (founded in 1933), and it was more aligned with modernism than with The Movement. So, it would not have been closely associated with The Movement.
London Mercury: This was a literary magazine that also predated The Movement. It was associated with an earlier era and was not particularly linked to the 1950s Movement.
New Poems: This anthology (published in 1956) featured work by poets closely associated with The Movement, such as Kingsley Amis and Philip Larkin. It is thus linked to The Movement.
Now, looking at the options:
I and IV (Departure and New Poems) are both associated with The Movement, which makes option 3 correct.
