The dog that chewed up my new shoes is named oscar whats the sub clause

hello,

your answer is a) the metaphor suggests that the poetic themes are serious and dark.

collins is comparing the poem to a dark room. he is suggesting that the poems theme is serious and wants you to understand it. you don't need to understand the poet in order to understand the poem. you also don't need to move around while reading it. he is simply saying the poem has a dark and serious theme.

- i.a -

i do not the question is put in the corrorect order

it would be d because the however is more proper and the comma is placed in the right spot
