Correct option is D
Correct answer: D — BADC
Correct rearranged sentence
I was sceptical that the dancers could engross an audience large enough to fill the arena.
Explanation of the sequence B → A → D → C
Part B: “I was sceptical that”
· This works as the introductory main clause.
· The conjunction “that” signals that a subordinate clause will follow.
Part A: “the dancers could”
· This provides the subject and modal verb of the subordinate clause introduced by “that.”
· “Could” sets up the action that follows.
Part D: “engross an audience large”
· This gives the main action and the object.
· “Engross” logically follows “could.”
Part C: “enough to fill the arena”
· This is a qualifying phrase that completes the idea by describing the size of the audience.
· It correctly modifies “audience large.”
Why other sequences do not work
· CDAB / ABDC / DCBA disrupt either:
o the logical subject–verb order, or
o the correct placement of qualifiers (“large enough”), making the sentence ungrammatical or awkward.
· No rearrangement required is incorrect because the original order does not form a meaningful sentence.
Final answer
