Odd One Out Question 3 - CAT 2024
Question
- To create a synapse, the neuron has specialized structures, often seen as tiny swellings, at its terminal end of the axon where it stores the chemicals that are emitted to transmit a signal to the next neuron.
- This fetal warm-up act—the soldering of neural connections before the eyes actually function—is crucial to the performance of the visual system.
- The reasons for this paring back of synapses is a mystery, but synaptic pruning is thought to sharpen and reinforce the “correct” synapses, while removing the weak and unnecessary ones.
- Neural connections between the eyes and the brain are formed long before birth, establishing the wiring and the circuitry that allow a child to begin visualizing the world the minute she emerges from the womb.
- During this rehearsal period, synapses—points of chemical connection—between nerve cells are generated in great excess, only to be pruned back during later development.
Step-by-Step Explanation
Correct Answer: 1 Explanation: Statements (4), (2), (5), and (3) explain how neural connections develop before birth and how extra synapses are later removed to improve the functioning of the visual system. Statement (1) is the odd one out because it gives a technical description of how a synapse works, rather than discussing brain development.Odd One Out Shortcuts & Tricks
Quick Tips for CAT Odd One Out Questions
Find the central idea: Understand what the paragraph is primarily discussing.
Look for sentence pairs: Identify sentences that have a strong logical connection.
Track the flow: Check how one idea leads naturally to the next.
Spot the disconnect: The odd sentence may be relevant to the topic but not to the sequence.
Verify your answer: Remove the odd sentence and check if the remaining four form a coherent paragraph.
