Directions (46-50): In each of the questions given below three words are given in bold. These words may or may not be in their correct position. Following each sentence few sequences are provided. Select the sequence of the words which will make the given sentence contextually meaningful. In the world of modern **technology (A)**, the inner workings of cutting-edge quantum computers may seem **esoteric (B)** to most, but the smartphones we use daily have become utterly **ubiquitous (C)**, altering the way we live and connect with the world.

### Concept & Contextual Semantics Read the sentence to identify the tone and factual relationships between the subjects. Look for contrast keywords like "but" which dictate how the adjectives should relate to one another. ### Step-by-Step Solution * **First word:** "modern technology (A)" is a standard, correct phrasing. * **Second word:** Quantum computers are highly complex and understood by very few people. The word "esoteric (B)" perfectly describes this condition. * **Third word:** The sentence uses "but" to contrast quantum computers with smartphones we use daily. Smartphones are everywhere. The word "ubiquitous (C)" means found everywhere. * All three words fit perfectly into their original positions. ### Exam Strategy & Shortcut Focus on the conjunction "but". It sets up a contrast between "inner workings of quantum computers" (rare, confusing, specialized) and "smartphones" (common, everywhere). "Esoteric" and "ubiquitous" form this exact logical contrast. ### Common Pitfall Getting confused by advanced vocabulary words like "esoteric" and "ubiquitous" and blindly guessing a rearranged option. ### Final Answer Therefore, the correct answer is **ABC**.
