I got 24 as E and 27 as D which are incorrect.

Could anyone please explain this to me?

Q. 27: is tricky one, but you can use POE to get the correct answer.

(A) Unlike Beethoven, however, even the greatest of
modern composers, such as Stravinsky, did
not transcend existing musical forms.
This is opposite of what we expect the conclusion to be.

(B) In similar fashion, existing musical forms were
even further exploited by the next generation
of great European composers.
Only best answer among all.

(C) Thus, many of the great composers displayed
the same combination of talents exhibited by
Monteverdi.
"Many of the great composers" is a too strong to conclude the passage.

(D) By contrast, the view that creativity in the arts
exploits but does not transcend limits is supported in the field of literature.

We have to read the answer choices super carefully as Carcass mentioned, nothing mentioned in the passage related to field of literature, so this option is incorrect.

(E) Actually, Beethoven's most original works were
largely unappreciated at the time that they
were first performed.

Not mentioned anything about Beethoven's how someone responded to his original works.

25: (A) - After POE, I was left with option A and C. Author was not confident whether creative art was generalised too and gave both ways example - one was of orchestra, another was of Beethoven

26: (E) - creative art in science gave generalised solution

27: (B)
