In the following question, out of the four alternatives, select the one which best expresses the meaning of the idiom/phrase: “A walk of life”.

Introduction / Context:
This question tests your understanding of a common English idiom: “a walk of life”. Idioms are fixed expressions whose meanings cannot always be guessed from the literal meanings of their individual words. You must know or infer what the phrase means when it is used in sentences like “People from all walks of life attended the event.”

Given Data / Assumptions:

• Idiom: “a walk of life”.
• Options:
  • An easy comfortable life not necessarily prosperous.
  • The most important day of your life.
  • A person's occupation or position within society.
  • Walking is the best form of exercise.
• We need the option that reflects the widely accepted idiomatic meaning.
• Typical usage: “from all walks of life” = from all types of jobs, backgrounds and social positions.

Concept / Approach:
In English, someone's walk of life refers to their type of job, career, social status or general position in society. When we say “people from all walks of life”, we mean people from many different professions and social backgrounds. It does not refer literally to walking, nor to a particular day or level of comfort in life. Therefore, the option that speaks about a person's occupation or position within society best captures the idiomatic sense.

Step-by-Step Solution:
Recall the common phrase: “from all walks of life”.Interpret that phrase: it clearly refers to people from different professions and social classes, such as teachers, doctors, farmers, workers and business people.Match this to the options: “A person's occupation or position within society” is exactly what walk of life describes.Check the other options: they refer to comfort, a specific day, or literal walking, which are not supported by typical usage.Therefore, the correct answer is the option describing occupation or social status.

Verification / Alternative check:
Use the idiom in a sentence: “The committee included people from every walk of life, including engineers, artists, farmers and doctors.” If we try to interpret walk of life as “the most important day of your life” or “an easy comfortable life”, the sentence becomes illogical. But if we read it as “every occupation or social background”, the sentence makes perfect sense. This confirms that the third option is correct.

Why Other Options Are Wrong:
“An easy comfortable life not necessarily prosperous” misreads walk as a smooth journey and invents a meaning that is not supported by actual usage. “The most important day of your life” would be expressed as “the biggest day of your life” or “the day of your life”, not “walk of life”. “Walking is the best form of exercise” interprets the phrase literally, ignoring its established idiomatic sense. None of these captures the job or social-position aspect central to the idiom.

Common Pitfalls:
Students sometimes assume that walk must have something to do with moving on foot and therefore choose options connected with physical activity. However, idioms like “walk of life” must be treated as fixed units. A good strategy is to recall a common sentence that uses the idiom, such as “people from all walks of life”, and see what that sentence logically means in everyday English. Doing this quickly points you to the idea of different professions and social roles, making such questions easy marks in the exam.

Final Answer:
The idiom “A walk of life” means a person's occupation or position within society.
