Parajumbles Question 1 - CAT 2020
Question
- Complex computational elements of the CNS are organized according to a “nested” hierarchic criterion; the organization is not permanent and can change dynamically from moment to moment as they carry out a computational task.
- Echolocation in bats exemplifies adaptation produced by natural selection; a function not produced by natural selection for its current use is exaptation — feathers might have originally arisen in the context of selection for insulation.
- From a structural standpoint, consistent with exaptation, the living organism is organized as a complex of “Russian Matryoshka Dolls” — smaller structures are contained within larger ones in multiple layers.
- The exaptation concept, and the Russian-doll organization concept of living beings deduced from studies on evolution of the various apparatuses in mammals, can be applied for the most complex human organ: the central nervous system (CNS).
Step-by-Step Explanation
- Correct Sequence: 2431
- Explanation: Sentence 2 functions as the overarching opening statement, introducing the baseline evolutionary concept of exaptation with real-world biological examples (bat echolocation and feathers). Sentence 4 directly borrows this freshly defined evolutionary context ("The exaptation concept...") and introduces a new application framework: mapping it onto the human central nervous system (CNS). Sentence 3 serves to clarify the geometric blueprint required for this mapping, explaining that from a structural standpoint consistent with exaptation, an organism is organized sequentially like nested "Russian Matryoshka Dolls." Sentence 1 concludes by defining the precise computational rules of this nested structural layout inside the CNS.
- FundaMakers Tip: Mapping Core Frameworks First. When an technical paragraph transitions from an abstract theory to a specific biological organ, find the conceptual introduction first. Sentence 2 defines the term exaptation. Sentence 4 explicitly hooks onto that definition ("The exaptation concept...") to bridge the gap over to the CNS. This establishes a clean 2-4 introductory anchor.

Importance of Para Jumbles in CAT VARC
Para Jumbles are an important part of CAT VARC preparation as they test both comprehension and logical reasoning. Here’s why practising them matters:
- Tests logical sequencing: Para Jumbles assess your ability to arrange disconnected sentences into a meaningful and coherent paragraph.
- Improves understanding of paragraph structure: Regular practice helps you recognise how an idea is introduced, developed and concluded.
- Strengthens contextual understanding: You learn to understand the relationship between sentences instead of interpreting each sentence in isolation.
- Develops clue identification: Para Jumbles train you to spot pronouns, connectors, transition words, mandatory pairs and other sequencing clues.
- Improves reading comprehension: Understanding the flow of ideas can also help you process passages and arguments more effectively in VARC.
- Builds accuracy through practice: Solving previous year Para Jumble questions familiarises you with the patterns and difficulty level seen in CAT.
