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

Step 1: Determine the central theme of the grouping.
Sentences 1, 2, 4, and 5 form a highly specific scientific paragraph discussing neuroscientists, proteins, and the microscopic impact of exercise on brain biology and genes.

Step 2: Identify the thematic outlier.
Sentence 3 is a broad, philosophical observation about technology and modern sedentary lifestyles. It does not fit the microscopic, clinical tone of the rest of the sentences.
