Explanation: Phrasal verbs are an important aspect of English language learning, especially in contexts like competitive examinations where understanding idiomatic expressions is crucial. "Set off" is a phrasal verb that means to start a journey or begin an activity. It is commonly used in travel contexts, such as "set off on a trip" or "set off for a destination."
In the given sentence, "Arjun and his family members set off on a trip to Bangalore," the phrasal verb "set off" is used to indicate the beginning of their journey. The verb "set" combined with the preposition "off" creates a new meaning that is different from the individual meanings of the words. "Set" alone can mean to place or arrange, while "off" can mean away or apart. Together, they form a phrasal verb that specifically means to start a journey.
It is important to understand the context in which phrasal verbs are used. In this case, the context is a trip, and "set off" clearly indicates the start of the journey. Other phrasal verbs related to travel include "set out," which can also mean to start a journey, but it can have other meanings as well, such as to propose or to begin an action. "Set up" means to arrange or prepare something, which is different from "set off."
Understanding the nuances of phrasal verbs is essential for accurate comprehension and usage in both written and spoken English. In competitive examinations, questions often test the ability to identify the correct meaning of phrasal verbs in specific contexts. Therefore, it is crucial to practice and familiarize oneself with common phrasal verbs and their meanings to avoid common misconceptions and to answer such questions correctly.
