Correct option is D
The correct answer is (D) Only (A)-(D) and (B)-(C).
Step-by-Step Analysis
To solve this, let's look at the context of the sentence and the parts of speech required for each position:
- Position (A): The sentence begins "China claims Taiwan as its own..." The word expanding (a verb/participle) doesn't fit here. We need a noun to describe what Taiwan is to China. Territory (D) fits perfectly.
- Position (B): "...to be brought under its [word] by force..." We need a noun here. Rapidly is an adverb and doesn't fit. Control (C) is the logical noun for being "under someone's control."
- Position (C): "...and has been [word] its military..." Since the sentence uses "has been," we need a present participle (-ing form) to show an ongoing action. Expanding (A) fits perfectly here.
- Position (D): The sentence ends describing how it is expanding its military: rapidly (B). This adverb correctly modifies the action of expanding.
The Logical Replacements
- A ↔ D: Replace "expanding" with territory.
- B ↔ C: Replace "rapidly" with control.
Corrected Sentence
China claims Taiwan as its own territory (D) to be brought under its control (C) by force if necessary, and has been expanding (A) its military rapidly (B) to meet that challenge.
Why the other options are wrong:
- A, B, & C: These combinations leave words in positions where they are grammatically incorrect (e.g., using an adverb like "rapidly" where a noun is needed).
- E: The original sentence is a "word salad" where verbs and adverbs are acting as nouns, making it nonsensical.
