can you please help me these questions because i'm having a hard time understanding the paper:

Answer the following questions:

6) Does the discussion carefully lay out an argument that supports the hypothesis? If not, what do you believe was missing?

7) Does the statistical analysis strengthen or weaken the conclusions of the paper.

8) What are the conclusions of the paper? Do you agree with the conclusions?

9) Does the author overstate their findings or perhaps not enough?

Explanation / Answer

6) The hypothesis that was tested in the article was, "epistatic interactions between mutations can make evolutionary trajectories contingent on the chance occurrence of initial mutations". The authors had laid out their argument in support of the hypothesis. But, it can be made in a more structured way.

7) The statistical analysis has strengthened the conclusions of the paper.

8) The paper concludes that the fitness evolution follows a predictable trajectory. The conclusion is agreeable.

9) The author's have overstated their findings in this study by making observations on beneficial mutations in addition to the primary objective.
