Question

Five sentences related to a topic are given below. Four of them can be put together to form ameaningful and coherent short paragraph. Identify the odd one out. Choose its number as your answer and key it in.

• A. Neuroscientists have just begun studying exercise's impact within brain cells — on the genes themselves.
• B. Even there, in the roots of our biology, they've found signs of the body's influence on the mind.
• C. 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.
• D. 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.
• E. 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

Answer 1

The Correct Option is D

To determine which sentence does not fit with the others in forming a coherent paragraph, we need to identify the main theme shared by four of the sentences. The sentences relate to the impact of physical exercise on the brain and neuroscience discoveries:

• The first sentence describes neuroscientists studying the effect of exercise on brain cells and genetics.
• The second sentence mentions finding signs of the body's influence on the mind at the genetic level.
• The third sentence explains how muscle movement produces proteins that affect brain mechanisms related to thought processes.
• The fifth sentence highlights recent neuroscience discoveries regarding these factors and their significance.

These four sentences are interconnected, discussing scientific findings about the physical impact on the brain. However, the fourth sentence shifts focus to how technology impacts our physical movement, rather than contributing to the neuroscience theme. Hence, the odd sentence out is:

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.
