Answer:
pulling further back on the string
Explanation:
I chose that because as for me answer 2 and 3 don't make sense but as for answer four I don't think that when you decrease the mass of the arrow this will increase the kinetic energy because for it to move faster I'll have to pull the string harder or to enlarge it ,so to increase the kinetic energy it is just determined by how I pull that string ."have I enlarged it or it is still loose."

Option A cannot be true since a scientific hypothesis must be testable, otherwise it is not scientific.
Option C is incorrect as well as scientific knowledge DOES need peer review and verification before the results are accepted by the scientific community.
Option D is also false as science is always changing and adapting. What this means is that conclusions or understandings can be changed if new evidence surfaces that suggests otherwise.
Therefore, the only correct answer is B) Explanations are based on observations, evidence, and testing.
This is true as we cannot make statements or explanations in science without first conducting tests, making observations and gathering evidence to support our claims.
