CAT 2017 Slot 1 — VARC Question 33

Mixed PracticeEasy

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 began 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. It turns out that moving our muscles produces proteins that travels through the bloodstream and into the brain, where they play pivotal roles in the mechanisms of our highest thought processes.
  4. 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.
  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.

Answer & solution

Correct answer: 4

Answer: 4

Solution

Easy

Odd-sentence-out: find the shared theme of four sentences, then the intruder. Four sentences describe a specific scientific finding — that exercise affects the brain at the level of genes and proteins. The misfit will be a general cultural comment, not part of that finding.

1

Establish the core thread. Sentence 1 introduces the research — neuroscientists studying exercise's impact within brain cells, "on the genes themselves." Sentence 2 continues "Even there, in the roots of our biology, they've found signs of the body's influence on the mind." Sentence 3 gives the mechanism (muscle movement produces proteins that reach the brain), and sentence 5 comments that only recently have neuroscientists "begun to describe these factors." Together 1–2–3–5 form one coherent paragraph about the body-to-brain biology.

2

Isolate the misfit: 4. Sentence 4 — "In today's technology-driven, plasma-screened-in world, it's easy to forget that we are born movers… because we've engineered movement right out of our lives" — is a general lament about a sedentary lifestyle. It does not deal with genes, proteins or neuroscientists' findings, and it has no link word tying it to the chain. It is the odd one out.

The odd sentence is 4 (a sedentary-lifestyle comment, not part of the biological finding). Key in 4.
