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.

All five sentences revolve around a philosophical discussion of freedom over death: what it means, why it matters, and how it shapes debates like assisted dying. Most of the sentences develop an argument about freedom as a moral and philosophical idea, not just popular opinion.

Sentences 5, 1, 2, and 3 follow a clear progression. Sentence 5 opens the discussion by noting that freedom is philosophically complex and sets a thoughtful tone. Sentence 1 then focuses on a specific kind of freedom, freedom over death, and places it in a historical and moral context. Sentence 2 builds on this by arguing that this freedom should be central to the broader debate. Sentence 3 then presents legalised assisted dying as a policy or ethical step toward realising this freedom.

Sentence 4 interrupts this flow. Rather than adding to the author’s conceptual argument, it makes a descriptive claim about what “many people endorse” in practice. This reference to public opinion is not needed or connected to the philosophical progression of the other sentences. As a result, it feels off-topic instead of supporting the main argument. So, sentence 4 is the one that does not fit.
