Q1b has a typo in the Report.docx.

1b. How does the performance compare between the lock-based triangle counting (you implemented in Assignment 2) and atomic-based counting (released in this assignment).

This should read

1b. How does the performance compare between the lock-based pagerank (you implemented in Assignment 2) and atomic-based counting (released in this assignment). If you implemented atomic in assignment 2 (then compare against that).

Wait, we're comparing lock-based pagerank against atomic-based triangle counting? I thought we would compare assignment 2's pagerank against this assignment's pagerank

Should the question not be labelled as 4b) ? so that it is under the pagerank questions and not 1), which pertains to triangle count

Yes; 4b) How does the performance compare between the lock-based pagerank (you implemented in Assignment 2) and atomic-based counting (released in this assignment). If you implemented atomic in assignment 2 (then compare against that).

So just to clarify, there is no longer a 1b to answer in the report but there is a 4b which relates to pagerank and not triangles?
