NinetynineCAT 2025 Slot 3 VARC Q2 Odd Sentence Out
Question 2 of the Verbal Ability & Reading Comprehension (VARC) section, CAT 2025 Slot 3, with CAT's official answer and a worked solution.
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. About half of all the oxygen we breathe is made near the surface of the ocean by phytoplankton that photosynthesize just like land-dwelling plants.
2. A team of scientists that includes Boston University experts has discovered they also produce oxygen on the seafloor.
3. The research team used deep-sea chambers that land on the seafloor and enclose the seawater, sediment, polymetallic nodules, and living organisms.
4. The discovery is a surprise considering oxygen is typically created by plants and organisms with help from the sun—not by rocks on the ocean floor.
5. The deep-sea rocks, called polymetallic nodules, don't only host a surprising number of sea critters.

Answer: 3 Odd Sentence Out TITA
Solution
- 1 (phytoplankton make oxygen near the surface), 5 (deep-sea nodules do more than host critters), 2 ('they also produce oxygen on the seafloor') and 4 (surprising, since oxygen usually comes from sunlight-driven organisms) form one paragraph about the discovery.
- 3 describes the experimental apparatus, a methodological detail that breaks the paragraph's focus on the discovery and why it is surprising. It is the odd one out.
