Which practice helps protect you from microorganisms?

• A. Wash hands.
• B. Antibiotics cure diseases.
• C. Antibiotics cure fungi or viruses.
• D. Eating yogurt harms healthy bacteria.

Answer: (A)

Keeping hands clean through washing is a simple, effective way to protect yourself from microorganisms. Soap and water remove or kill many germs you pick up from touching surfaces or other people, and scrubbing for about 20 seconds helps break up the oils on your skin where microbes live. Rinsing them away prevents you from transferring germs to your eyes, nose, or mouth or to someone else, lowering your chances of getting sick. Antibiotics are meant to treat infections after they occur and target bacteria, not the everyday germs you might encounter. They don’t prevent exposure to microorganisms and aren’t a general protective habit. Eating yogurt with live cultures can support a healthy gut, but it isn’t a reliable method for preventing illnesses caused by germs. So washing hands is the best protective practice among these options.
