Answer:
all are False
Explanation:
1. Working in the US does nothing to ensure you will have an adequate retirement benefit. Social security may provide a little income, but usually won't pay the rent.
2. 403(b) plans may be offered by some tax-exempt organizations--not by corporations. Corporations may offer a 401(k) plan.
3. IRA stands for "Individual Retirement Account."
4. It is a good idea to invest in a retirement account at a young age so you can take advantage of interest compounding. Using the money for anything other than retirement is not recommended.
