 ## Task 1
 
-The one and only task in this article concerns accessing JSON data and using it in your page. JSON data about some mother cats and their kittens is available at [sample.json](sample.json). The JSON is loaded into the page as a text string and made available in the `catString` parameter of the `displayCatInfo()` function, called when the provided promise chain (which starts by fetching the JSON data) is fulfilled. Your task is to fill in the missing parts of the `displayCatInfo()` function to output:
