Chapter 3 exercise - different answer for number of columns

[Michel_Dias]

Hi, I was doing my exercise for Chapter 3, and when I checked the answer for the first question, it says that there are 67 columns in the 1960s data, but when I uploaded this data on my workspace it shows only 64 rows, can you help me understanding what could be the issue here? Thanks

Hi Michel,

Thanks for pointing this out. We left an outdated screenshot in the guide. It should indeed be 64 columns. We will fix that.
