The correct answer is 3. a personal “snapshot” of how you have spent your time.

You can arrive at this answer by understanding the meaning and purpose of a résumé. A résumé is a document that provides a summary of an individual's education, work experience, skills, and other relevant qualifications. It serves as a snapshot of a person's background, accomplishments, and capabilities.

While option 1 describes a résumé as a detailed account of activities, it may not necessarily include all activities. Résumés typically focus on relevant experiences and qualifications that are directly applicable to a job or educational opportunity.

Option 2 is incorrect because while a résumé may support the process of securing letters of recommendation, its primary purpose is to highlight the individual's qualifications and experiences to demonstrate their suitability for a job or educational pursuit.

Option 4 is partially correct as a résumé is indeed commonly used as a tool to apply for job opportunities, but it is not the sole purpose of a résumé. Résumés can also be used when applying for internships, scholarships, graduate programs, or other opportunities where a person's background and qualifications need to be showcased.

In conclusion, option 3 accurately describes a résumé as a personal “snapshot” of how you have spent your time, capturing the essential aspects of a person's education, work history, and relevant skills.
