I want to know the answer to the following question:
Toward what does Popper believe scientific understandings progress?
All the background I'm provided with is that "Yet, as it appears that the engine of biological evolution has, over many generations, produced adaptive traits equipped to deal with more and more complex problems of survival, likewise, the evolution of theories through the scientific method may, in Popper's view, reflect a certain type of progress: toward more and more interesting problems ().". Is that enough to answer the question?
Answer: yes
