Which writer does not belong to the angry young men movement?

The correct options are Seamus Heaney and Philip Larkin.

The "Angry Young Men" was a trend-defining group of working- and middle-class British novelists and playwrights who emerged in the 1950s. Their works were characterized by disillusionment with traditional British society, class distinctions, and the political establishment. Key figures associated with this movement include playwright John Osborne (famous for his 1956 play Look Back in Anger) and novelist Kingsley Amis (known for his 1954 novel Lucky Jim).

In contrast:
1. Seamus Heaney was an Irish poet and playwright who rose to prominence in the 1960s. He is widely recognized for his poetry focused on Irish history, culture, and the Northern Irish landscape, and he was awarded the Nobel Prize in Literature in 1995. He was never a part of the British "Angry Young Men" movement.
2. Philip Larkin was an English poet and novelist associated with "The Movement," a group of writers who rejected the romanticism and modernism of the 1940s in favor of clarity, restraint, and traditional forms. While he shared some mid-century English skepticism, his work belongs to a distinct poetic tradition rather than the "Angry Young Men" literary group.
