Question:medium

Five jumbled up sentences (labelled 1, 2, 3, 4 and 5), related to a topic, are given below. Four of them can be put together to form a coherent paragraph. Identify the odd sentence and key in the number of that sentence as your answer.

  • To create a synapse, the neuron has specialized structures, often seen as tiny swellings, at its terminal end of the axon where it stores the chemicals that are emitted to transmit a signal to the next neuron.
  • This fetal warm-up act—the soldering of neural connections before the eyes actually function—is crucial to the performance of the visual system.
  • The reasons for this paring back of synapses is a mystery, but synaptic pruning is thought to sharpen and reinforce the “correct” synapses, while removing the weak and unnecessary ones.
  • Neural connections between the eyes and the brain are formed long before birth, establishing the wiring and the circuitry that allow a child to begin visualizing the world the minute she emerges from the womb.
  • During this rehearsal period, synapses—points of chemical connection—between nerve cells are generated in great excess, only to be pruned back during later development.

The Correct Option is A

Solution and Explanation

The sentences discuss neural development and synaptic activity. We need to find the sentence that doesn't fit the main theme by analyzing how each contributes to a cohesive narrative:
  • Sentence 1 describes the specialized structures of neural synapses.
  • Sentence 2 mentions prenatal neural development and preparation of the visual system.
  • Sentence 3 explains synaptic pruning, a normal part of neural development.
  • Sentence 4 talks about how neural connections between the eyes and brain form before birth.
  • Sentence 5 explains that synapses are initially produced in excess and then pruned.
Sentences 2, 3, 4, and 5 all focus on fetal development, the overproduction of synapses, and pruning as the visual system matures. Sentence 1, however, shifts the focus to the physical structure of synapses, without connecting to the theme of early neural development and visual system preparation. Therefore, the sentence that doesn't belong is:
To create a synapse, the neuron has specialized structures, often seen as tiny swellings, at its terminal end of the axon where it stores the chemicals that are emitted to transmit a signal to the next neuron.

The passage given below is followed by four summaries. Choose the option that best captures the essence of the passage.
In the dynamic realm of creativity, artists often find themselves at the crossroads between drawing inspiration from diverse cultures and inadvertently crossing into the territory of cultural appropriation. Inspiration is the lifeblood of creativity, driving artists to create works that resonate across borders. In a globalized era of the modern world, artists draw from a vast array of cultural influences. When approached respectfully, inspiration becomes a bridge, fostering understanding and appreciation of cultural diversity. However, the line between inspiration and cultural appropriation can be thin and easily blurred.
Cultural appropriation occurs when elements from a particular culture are borrowed without proper understanding, respect, or acknowledgment. This leads to the commodification of sacred symbols, the reinforcement of stereotypes, and the erasure of the cultural context from which these elements originated. It is essential to recognize that the impact of cultural appropriation extends beyond the realm of artistic expression, influencing societal perceptions and perpetuating power imbalances.
