Score

As you can see, I scored a 46/50 on the Tri 2 Final MCQ (92%)

Reviewing Questions that I missed:

The correct answer here is B, because lossless compression algorithms are guaranteed to be able to reconstruct the original data, while lossy compression algorithms are not.

The correct answer here is A, because lossless algorithms allow for complete reconstruction of the original data and typically reduce the size of the data.

The correct answer here is B and D, because sorting by year will sort the spreadsheet on column C from least to greatest. Filtering by year will remove any entries with unknown years. Filtering by photographer will remove any entries with unknown photographers. And since the order of the entries is not affected by the filters, the photograph with the lowest year value will be in the first row of the spreadsheet.
