Question

Five sentences related to a topic are given below. Four of them can be put together to form a meaningful and coherent short paragraph. Identify the odd one out:
1. Neuroscientists have just begun studying exercise's impact within brain cells on the genes themselves.
2. Even there, in the roots of our biology, they've found signs of the body's influence on the mind.
3. In today's technology-driven, plasma-screened-in world, it's easy to forget that we are born movers-animals, in fact, because we've engineered movement right out of our lives.
4. It turns out that moving our muscles produces proteins that travel through the bloodstream and into the brain, where they play pivotal roles in the mechanisms of our highest thought processes.
5. It's only in the past few years that neuroscientists have begun to describe these factors and how they work, and each new discovery adds awe-inspiring depth to the picture.

• A. Sentence 1
• B. Sentence 2
• C. Sentence 3
• D. Sentence 4
• E. Sentence 5

Hint:

In para-jumble "odd one out" questions, look for shifts in scope. A sentence speaking broadly about society usually doesn't belong in a paragraph detailing cellular biology.

Answer 1

The Correct Option is C

The task is to arrange the given sentences to form a coherent and meaningful paragraph, subsequently identifying the sentence that is the odd one out. Let's evaluate each sentence to identify its role in forming a complete paragraph:

1. Sentence 1: "Neuroscientists have just begun studying exercise's impact within brain cells on the genes themselves."
   This introduces the topic of the neuroscientific study of exercise impacts on brain cells.
2. Sentence 2: "Even there, in the roots of our biology, they've found signs of the body's influence on the mind."
   This continues from Sentence 1, emphasizing discoveries about the body's influence on the mind, fitting well as supporting evidence.
3. Sentence 3: "In today's technology-driven, plasma-screened-in world, it's easy to forget that we are born movers-animals, in fact, because we've engineered movement right out of our lives."
   This sentence introduces an unrelated idea about modern sedentary lifestyles, which does not directly link to the neuroscientific focus.
4. Sentence 4: "It turns out that moving our muscles produces proteins that travel through the bloodstream and into the brain, where they play pivotal roles in the mechanisms of our highest thought processes."
   This elaborates on the findings related to physical activity and its impacts on brain functionality.
5. Sentence 5: "It's only in the past few years that neuroscientists have begun to describe these factors and how they work, and each new discovery adds awe-inspiring depth to the picture."
   This continues the discoveries mentioned in Sentences 1 and 2, adding depth and recent developments to these ideas.

When arranging these sentences to form a coherent paragraph, Sentences 1, 2, 4, and 5 cohesively discuss the neuroscientific observations and findings regarding physical exercise's influence on the brain. Sentence 3, however, diverges from this main theme with a more general observation about lifestyle changes in modern society.

Therefore, Sentence 3 is identified as the odd one out, as it does not fit with the narrative created by the other sentences focused on neuroscientific studies and findings.
