Which characteristic would be most important when a scientist needs to study the changes in climate conditions over a five year period

I think the answer is observant since the scientist needs to really pay attention and look at all the details.

observant

Explanation:

The scientists must be observant. This is because of the fact that the observation involves the examination and monitoring something on the basis of different parameters such as shape, form, color, duration for accomplishment of a reaction and others.

If the scientists studies and observe the the climate pattern for a period of five years he must be able to identify the actual climate condition.

the answer is b: 1.4 km/hr

nucleus

would be most reasonable answer tbh
