Five jumbled up sentences, related to a topic, are given below. Four of them can be put together to form a coherent paragraph. Identify the odd one out and key in the number of the sentence as your answer: 1. There is a dark side to academic research, especially in India, and at its centre is the phenomenon of predatory journals. 2. But in truth, as long as you pay, you can get anything published. 3. In look and feel thus, they are exactly like any reputed journal. 4. They claim to be indexed in the most influential databases, say they possess editorial boards that comprise top scientists and researchers, and claim to have a rigorous peer-review structure. 5. But a large section of researchers and scientists across the world are at the receiving end of nothing short of an academic publishing scam.

Correct answer: 5
Let's find the one sentence that does not belong with the other four.
Step 1 — Identify the topic and the opener
Sentence 1 is the natural opener: it introduces the subject — predatory journals as the "dark side" of academic research, especially in India. It sets up a description of what these journals are.
Step 2 — Build the descriptive chain
Once predatory journals are introduced, the other sentences should logically describe them:
- Sentence 4 lists their false respectability — they claim prestigious indexing, eminent editorial boards, and rigorous peer review.
- Sentence 3 follows naturally with "In look and feel thus…" — the word thus ties directly to sentence 4's claims: because they make all those boasts, they look and feel exactly like any reputed journal.
- Sentence 2 then delivers the punchline: "But in truth, as long as you pay, you can get anything published." The contrast word But flips the respectable appearance into the ugly reality.
So the coherent paragraph is: 1 → 4 → 3 → 2 — a tight chain that introduces predatory journals, describes their deceptive claims, notes their convincing appearance, and then reveals the truth.
Step 3 — Why sentence 5 breaks the chain
Sentence 5 says: "But a large section of researchers and scientists across the world are at the receiving end of nothing short of an academic publishing scam."
This sentence shifts the focus from describing what predatory journals are to describing who suffers from them worldwide. It introduces a new subject — the global victim population — that the other four sentences never develop.
There's also a structural clue: sentence 2 already opens with "But in truth…" Placing another "But" immediately afterward (sentence 5) would create an awkward double-contrast with no clean anchor.
💡 Teacher tip: In Odd-One-Out, look for the sentence that changes whose story is being told. Here, sentences 1-4-3-2 all describe the journals themselves; sentence 5 suddenly switches to the victims — a different thread.
