What is one way that testing helps scientists determine which solution for a problem works best?

Testing allows scientists to rely on abductive reasoning rather than inductive and deductive reasoning.

Testing can help them understand where they went wrong, and see if it works.

Explanation:

How can testing actually determine which solution for a problem works best? Well let me try and answer that for you! Instead of just diving in blind, you are diving in with the ability to see the problem after-ward, and how it can cause chaos. If the solution ends up correct in the end then the test went great. But if you like said, go in blindly and just make up an solution and add it together with the others it could cause death, third-degree burns, pain, or other horrible things.

 Though I might not be 100% accurate about this answer, or the explanation, I really do hope I helped you out though.

explanation:

2b2t

the pronoun reference replaces a noun, but you have to make sure there's no room for confusion.

in the first sentence "her" could be referring to shely or to the sister. the answer there is "shelly called her sister and told her about the new baby."

in the second sentence "it" could be referring to the roof or the floor. the answer there is "since the roof leaks on the family room floor, we need to repair the roof."
