Which word best describes something that is "robust"?

  1. Weak

  2. Vigorous

  3. Fragile

  4. Delicate

The correct answer is: Vigorous

The term "robust" is often used to describe something that is strong, healthy, and able to withstand challenges or adverse conditions. In this context, "vigorous" perfectly captures the essence of what robust means. It conveys a sense of energy, strength, and durability. When used to describe a person, object, or system, being vigorous suggests that it is capable, resilient, and effective. The other terms do not align with the meaning of robust. For instance, "weak" implies a lack of strength, while "fragile" and "delicate" suggest an inability to withstand stress without breaking. These contrasts highlight the strength and resilience associated with the word "robust," helping to clarify why "vigorous" is the best descriptor among the choices provided.
