What does the term isolate mean?

• A. To separate from others
• B. To join with others
• C. To confuse
• D. To insult

Answer: (A)

Isolate means to set something apart from others or to keep it away from contact. It describes making a separation so that the thing stands apart, either physically or in how it’s treated. You might isolate a patient with a contagious disease to prevent spreading it, or isolate a variable in an experiment so you can observe its effect without interference. This sense of separation is what makes the meaning fit far better than ideas like joining with others, which would be the opposite, or concepts like confusion or insult, which don’t align with keeping something apart.
