The given sentences discuss the topic of legal matters and the commercialization of space. To identify the sentence that does not fit into a coherent paragraph, we should analyze how well each aligns with the central theme.
The coherent topic seems to be regarding the future of space law and its implications on commercial activities:
- Sentence 1 explains both the legal ambiguity and future market possibilities of space resources.
- Sentence 2 highlights the outdated nature of space law in the face of future commercial prospects.
- Sentence 3 discusses legislative steps taken by some countries and the limitations of these laws on the international stage.
- Sentence 5 outlines the shift from state exploration to private sector interest in space profit.
Meanwhile, Sentence 4 mentions criticism of the US' approach toward space law, implying international discontent. This does not align with the exploration of commercialization and legal expansion but instead focuses on geopolitical critique.
Thus, the sentence that does not fit into the sequence and disrupts the coherence is: Critics say the US is conferring rights that it has no authority to confer; Russia in particular has condemned this, citing the US’ disrespect for international law.
