2017 Section 1 Question 20

20) B

Looking at the graph of supplementary files, number of supplementary files in 2015 = 170

Number of journals = 18

Statement 1 is basically saying: At least half of the journals observed (0.5 x 18 = 9) published a paper whose supplementary files contained spreadsheet errors.

By looking at the data, this statement is clearly false.

Number of files with genome errors in 2011 > 100

Number of files with genome errors in 2009 = 50

Therefore, statement 2 is correct.

Number of papers in Nature with errors = 23

Number of papers in BMC Bioinformatics with errors = 21. So this is clearly false.

Since only statement 2 is correct, B is the answer.
