Explanation

The sentence suggests that the film is not well described by the conventional term “political thriller.” The film is not political but rather apolitical, and the phrase “as apolitical as it is . . .” sets up a parallel between “apolitical” and the blanked word; therefore, the blanked word should go against the term “political thriller” in the same way that “apolitical” does. “Humdrum” and “dull” are the opposite of “thrilling” and are therefore the best choices.

Thus, the correct answer is humdrum (Choice D) and dull (Choice F).

Let us first look for the clues in the sentence.

Firstly, the subject of the sentence – “the kind of movie”.

Secondly, what kind of word is required in the blank? The phrase leading up to the blank states – “but the film is as apolitical as it is….” The film is described as apolitical and the placement of the phrase “it is” just before the blank indicates that the blank provides another adjective.

Thirdly, the phrase “as….as” indicates a comparison with the quality of being apolitical.

And lastly, the words “conventionally described” and “but” indicate that the word in the blank signifies a quality opposite to the description of a thriller.

Taking all these clues into consideration, we can rule out option E, because ‘refined’ is a positive word and does not have anything to do with a thriller.

There is no indication that a thriller is obvious, so ‘subtle’, which means the opposite of obvious can also be ruled out.

There is no indication in the sentence of something that has happened before, so ‘unprecedented’, which means ‘never before seen or experienced’, does not suit the context.

A thriller would be described as ‘intense’, so since we need a word that is opposite in meaning, Option A also can be ruled out.

We are left with Options D and F. Humdrum and dull, which are similar in meaning fit into the blank as they also convey a meaning opposite to that of the description of a thriller.
