DIRECTIONS for questions: Five jumbled sentences (labelled 1, 2, 3, 4, and 5), related to a topic, are given below. Four of them can be put together to form a coherent paragraph. Identify the odd sentence out and key in the number of that sentence as your answer.

1. Developments both technological and sociocultural have afforded us far greater freedom over death than we had in the past, and while we are still adapting ourselves to that freedom, we now appreciate the moral importance of this freedom.

2. But I believe that a type of freedom we can call freedom over death – that is, a freedom in which we shape the timing and circumstances of how we die – should be central to this conversation.

3. Legalising assisted dying is but a further step in realising this freedom over death.

4. Many people endorse, through their opinions or their choices, our freedom over death encompassing a right to medical assistance in hastening our deaths.

5. Freedom is a notoriously complex and contested philosophical notion, and I won’t pretend to settle any of the big controversies it raises.

The correct answer is Option 4.

To identify the odd sentence out, we must first establish the logical sequence of the other four sentences to form a coherent paragraph. The central theme of the provided sentences is the philosophical concept of "freedom," specifically narrowed down to the author's conceptualization of "freedom over death." Let us break down the logical flow of the coherent sentences step-by-step.

Step 1: Identifying the opening sentence
Sentence 5 acts as the perfect introduction. It introduces the broad, complex, and contested philosophical notion of "Freedom" and sets up the context for a larger discussion.

Step 2: Finding the connecting sentence
Sentence 2 logically follows sentence 5. The phrase "this conversation" in sentence 2 directly refers back to the broad philosophical controversies mentioned in sentence 5. Here, the author shifts the topic from general freedom to a specific subset: "freedom over death."

Step 3: Elaborating on the specific concept
Sentence 1 then expands on this newly introduced concept of "freedom over death." It explains how technological and sociocultural developments have historically granted us this freedom and emphasizes that we are now recognizing its moral importance.

Step 4: Providing a concrete application
Sentence 3 logically concludes this thought progression. By using the phrase "this freedom over death," it directly connects back to the moral freedom discussed in sentence 1. It states that legalizing assisted dying is a concrete, further step in realizing this specific freedom.

Step 5: Analyzing the odd sentence
This leaves us with a highly coherent paragraph sequenced as 5-2-1-3. Sentence 4 is the odd one out. While it shares similar terminology (such as "freedom over death" and "medical assistance"), it introduces a completely different thematic angle. The coherent paragraph traces the author's personal philosophical argument from a broad concept to a specific legal application. Sentence 4, however, shifts the focus to public opinion and societal endorsement ("Many people endorse, through their opinions or their choices..."). This sudden shift to public consensus disrupts the author's conceptual and logical flow, making sentence 4 the odd sentence out.
