Hi @joseph-ProCogia , my feedback:

1. In question 1, plotly can be used for making data visualisations, I would remove it as answer or be more specific in the question
2. In question 4, this isn't quite right; summary will do different things depending on the class of the object given to it.
   3)Typo in question 5 "logrithmic"
3. I think question 7 might fit better in another category. We could actually refer to the native pipe here also.
4. In question 9, can dplyr do pca?
