Here's why and some alternatives:
* "Range" implies variety: The word itself suggests a collection of diverse things. Therefore, a collective noun would be redundant.
* Context Matters: The best way to describe a "range of" something depends on the context. For example:
* A range of colors: You could say "palette of colors" or "spectrum of colors."
* A range of emotions: You might use "spectrum of emotions" or "gamut of emotions."
* A range of products: You could say "assortment of products" or "selection of products."
Choose the word that best reflects the specific type of diversity or collection you're describing.
