Sentence Arrangement: Understanding the Question

The question presents a sentence with four words marked as (A), (B), (C), and (D). Our task is to identify if any of these words are misplaced and, if so, determine the correct rearrangement to make the sentence grammatically sound and meaningful. We need to select the option that indicates the correct swap between the words, or choose 'No arrangements' if the original sentence is already correct.

Analyzing the Original Sentence Structure

Let's examine the given sentence and the placement of the marked words:

"Although(A) she acts spending(B) , the teenager really does enjoy uninterested(C) time with her younger(D) sister."

• (A) Although: This word is a subordinating conjunction, commonly used to introduce a contrasting idea. Its placement at the beginning of the sentence to introduce a clause like "Although she acts..." is grammatically correct and makes sense in context. So, (A) seems to be in its correct position.
• (B) spending: The phrase "she acts spending" is awkward and grammatically incorrect. When we say "acts," we usually follow it with an adjective (e.g., "acts happy," "acts uninterested") or an adverb (e.g., "acts wisely"). "Spending" is a gerund or a present participle, which doesn't fit after "acts" in this context to describe *how* she acts.
• (C) uninterested: The phrase "enjoy uninterested time" is also illogical. "Uninterested" is an adjective describing a person's state of not being interested. Time itself cannot be "uninterested." However, "uninterested" could logically describe how someone "acts."
• (D) younger: The phrase "younger sister" is perfectly correct and common. "Younger" is an adjective describing the sister, indicating her age relative to someone else. So, (D) is in its correct position.

Identifying Word Misplacements

Based on our analysis:

• The word "spending" (B) is incorrectly placed after "acts." It doesn't make sense for someone to "act spending."
• The word "uninterested" (C) is incorrectly placed before "time." "Uninterested time" is not a meaningful phrase.

However, if we consider swapping (B) and (C):

• If "uninterested" (C) moves to the position of (B), the phrase becomes "she acts uninterested." This is grammatically sound and means she pretends not to be interested.
• If "spending" (B) moves to the position of (C), the phrase becomes "enjoy spending time." This is a common and correct idiom meaning to like engaging in an activity for a duration.

Therefore, a swap between word (B) and word (C) appears to resolve both grammatical issues and make the sentence coherent.

Correcting the Sentence Arrangement

Let's perform the swap of (B) and (C) and reconstruct the sentence:

Original: "Although(A) she acts spending(B) , the teenager really does enjoy uninterested(C) time with her younger(D) sister."

After swapping (B) and (C):

"Although(A) she acts uninterested(C) , the teenager really does enjoy spending(B) time with her younger(D) sister."

Evaluating the Corrected Sentence

The revised sentence reads: "Although she acts uninterested, the teenager really does enjoy spending time with her younger sister."

This sentence is now grammatically correct and makes perfect sense. It conveys that despite pretending to be uninterested, the teenager genuinely likes spending time with her younger sister.

Concluding the Correct Word Arrangement

The necessary rearrangement involves swapping the words at positions (C) and (B).

Thus, the words at positions C and B need to be interchanged. This corresponds to the option 'C - B'.
