Rearrange the given sentence fragments about party faithful and a political arrival into a single coherent English sentence.

Introduction / Context:
This is a sentence rearrangement question about political supporters and their changing expectations. The sentence begins with The party faithful, who and provides three fragments labelled P, Q, and R. The task is to order these fragments correctly to produce a coherent and grammatically accurate sentence. Such questions evaluate understanding of clause structure, relative pronouns, punctuation, and the logical progression of ideas within complex sentences.

Given Data / Assumptions:

The base clause is The party faithful, who which introduces a relative clause.

Fragment Q is had greeted his political arrival in 2004.
Fragment R is with great enthusiasm, and.
Fragment P is expectations, are now disillusioned.
We must choose the option that arranges these fragments to form a meaningful sentence about supporters who are now disillusioned.

Concept / Approach:
A relative clause that begins with who normally has the structure who plus verb phrase plus additional modifiers, followed by the main clause. Here, who clearly refers to the party faithful. First, we need a verb that tells what they did in the past. Fragment Q had greeted his political arrival in 2004 supplies that verb phrase and specifies the time. Next, we need adverbial detail about how they greeted him, and R with great enthusiasm, and gives that detail. Finally, P expectations, are now disillusioned completes the main clause by linking their earlier enthusiasm and expectations with their current state of disappointment. The natural order is therefore Q R P, which produces a smooth and logical sentence.

Step-by-Step Solution:
Step 1: Start with the fixed beginning The party faithful, who and look for the fragment that can follow who as the main verb of the relative clause. Step 2: Recognise that Q had greeted his political arrival in 2004 is a complete verb phrase suitable to follow who. Step 3: After this, consider additional details about the manner of greeting, which appear in R with great enthusiasm, and, so Q followed by R reads naturally. Step 4: Finally, connect the relative clause to the present state by adding P expectations, are now disillusioned, which returns to the main clause after the descriptive relative clause. Step 5: Combine everything into a full sentence: The party faithful, who had greeted his political arrival in 2004 with great enthusiasm, and expectations, are now disillusioned, matching the sequence Q R P.

Verification / Alternative check:
Test each suggested ordering. For R Q P, starting the relative clause with with great enthusiasm, and had greeted his political arrival in 2004 expectations feels grammatically broken and confuses the role of expectations. For P R Q, we get expectations, are now disillusioned with great enthusiasm, and had greeted his political arrival in 2004, which clearly disrupts both tense sequence and clause structure. For P Q R, the expectations fragment comes too early and interrupts the relative clause right after who. Only Q R P produces a sentence where the relative clause who had greeted his political arrival in 2004 with great enthusiasm, and expectations flows into the main clause are now disillusioned in a meaningful way.

Why Other Options Are Wrong:
Option A R Q P introduces with great enthusiasm, and directly after who, which lacks a main verb and leaves the reader waiting for the action. Option C P R Q incorrectly positions expectations immediately after who, which makes the clause structurally confusing and delays the main verb. Option D P Q R also misplaces expectations and leads to a sentence that does not clearly separate the description of past enthusiasm from the present disillusioned state.

Common Pitfalls:
A frequent difficulty in such questions is ignoring punctuation clues such as commas placed around relative clauses. Learners may also pay attention only to meaning fragments like enthusiasm or expectations without noticing that who must be followed by a complete verb phrase before any additional modifiers. Another pitfall is to choose the order that sounds somewhat familiar without reading the entire reconstructed sentence carefully. A practical strategy is always to identify the grammatical spine of the sentence first, specifically the subject, relative pronoun, and main verb, and only then attach additional phrases in places that keep the sentence smooth and logical.

Final Answer:
Q R P
