Barometers, instruments that measure atmospheric pressure, were once the best way to predict that a hurricane was coming. Today, scientists still study the changes in atmospheric pressure caused by hurricanes. They can also track hurricanes using satellite photography. What does the
change in how scientists study hurricanes indicate about scientific progress?
Scientists always look for new questions to investigate.
Scientists always use new variables when performing investigations.
Scientists must often choose between disagreeing data.
Scientists must often find ways to combine data from different sources.

Scientists always look for new questions to investigate.

Explanation:

Every scientific investigation begins with an observed problem, which in turn leads to a scientific question. This scientific question is the basis of the scientific method that leads to new discoveries.

In this question, barometers were once the best way to predict that a hurricane was coming. However, in recent times, hurricanes are now tracked using satellite photography. This new discovery about studying hurricanes is as a result of new questions that emerged. The new scientific questions, which are testable, led to a change in how scientists study hurricanes indicate.
