    "A client has been testing a [small form](index.html) to gather some basic data about their client-base. They have brought their findings to you to validate the data they have gathered. You can open the `index.html` page in a browser to take a look at the form.\r\n",

    "You have been provided a [dataset of csv records](../../data/form.csv) that contain entries from the form as well as some basic visualizations.The client pointed out that some of the visualizations look incorrect but they're unsure about how to resolve them.
