Question

question 16 (mandatory) (3.0303 points)
a model is useful

a) if it is new.

b) only if it always makes perfect predictions.

c) if it can explain some observations or events.

d) if it has been around for many years.

Explanation:

Models are academic/analytical tools designed to interpret real-world phenomena. Their utility comes from their ability to make sense of observations or events, not their age, novelty, or perfect predictive accuracy (perfect predictions are rarely achievable and not required for a model to be useful).

Answer:

c) if it can explain some observations or events.
