Within the context of the poem, lines 5-9 ("I was.. orchard") primarily serve to A

illustrate that the speaker has a positive relationship with her grandparents.

Su

B

explain why the speaker was initially reluctant to enter the "solid hedge."

С

contrast "real rooms" with the room the speaker creates for herself in the

raspberry patch.

D

compare the speaker's experiences as a child with her experiences as an

adult

A bit late but here's the B: explain why the speaker was initially reluctant to enter the “solid hedge.”

Explanation:

The lines are:

I was trying so hard to love this world—real rooms too big and full  of worry to comfortably inhabit—but believing I was born

to live in that cloistered green bower: the raspberry patch

in the back acre of my grandparents’ orchard.

B is the right answer because "I was trying so hard to love this world—real rooms too big and full  of worry to comfortably inhabit" is basically stating that the speaker was "trying" to love that world, but was unable to due to the fact that the speaker was worried.

what are the choises i cant answer without choises

sentences vary by structure as well as by function. there are compound, complex, and compound-complex sentences.

simple sentence

i like to read.

a simple sentence has one independent clause.

compound sentence

i like to read, and i also like to write.

a compound sentence includes more than one independent clause, connected by a coordinating conjunction (and, but, for, nor, or, so, or yet).

complex sentence

i prefer to read books that are bestsellers.

a complex sentence includes one independent clause and one or more dependent clauses. (a dependent clause is one that cannot stand alone.) types of dependent clauses include relative clauses (i kicked the boy who pinched me), adverb clauses (i am going home now because i have a curfew), and noun clauses (i don't know what to do next).

compound-complex sentence

although i prefer to read current bestsellers, i do like to read old agatha christie mysteries, and i also like some 20th-century science fiction.

compound-complex sentences take a bunch of clauses (multiple independent clauses, and one or more dependent clauses) and toss them together like a salad. although these sentences take practice to write in a grammatically correct fashion, they can hold a tremendous amount of meaning, and are common in academic writing.
