To identify the sentence that disrupts paragraph coherence, we must first analyze the flow and context of the provided sentences. Let's examine them:
1. Academic research, particularly in India, has a dark aspect, with predatory journals at its core.
2. However, in reality, publication is achievable with payment.
3. Their appearance and feel are identical to reputable journals.
4. They assert indexing in prominent databases, boast editorial boards of leading scientists, and claim rigorous peer review.
5. Nevertheless, a significant portion of global researchers and scientists are victims of an academic publishing scam.
Now, let's assess the coherence:
Sentence 1 introduces the problem of predatory journals in academic research.
Sentence 2 explains that payment guarantees publication in these journals, aligning with the predatory journal context.
Sentence 3 compares the appearance of predatory journals to legitimate ones, remaining on topic.
Sentence 4 details the deceptive claims made by predatory journals, reinforcing the main subject.
Sentence 5 shifts the focus from the journals themselves to their negative impact on researchers worldwide, a slight deviation from directly describing the journals.
Analysis indicates that sentence 5 discusses global consequences and moves away from a direct description of predatory journals. The other sentences collectively detail the characteristics and operations of these journals. Therefore, sentence 5 is less fitting within the sequence.
Consequently, the sentence that does not fit the coherent paragraph is:
But a large section of researchers and scientists across the world are at the receiving end of nothing short of an academic publishing scam.
