The question is incomplete, the complete question is;
A scientist would most likely need to update her model when it
a.has become too simple.
b.no longer supports the latest results.
c.reduces the need for verbal explanation of data.
d.no longer appears interesting.
Answer:
b.no longer supports the latest results.
Step-by-step explanation:
In science, models are prepared to explain experimental results. Each model must have a solid framework supported by experimental results.
However, science is never static. Given the dynamic nature of science, it is possible that latest experimental evidence may no longer support the existing model and the model will need to be reviewed in the light of emerging experimental results.
