Expert writing Tips
Best practice
In scientific or technical contexts, quantify the "length of the problem" whenever possible (e.g., "the three-year length of the problem") to provide precise information.
Common error
Avoid using "length of the problem" when you actually mean the scope or complexity of the problem. "Scope" refers to the breadth and depth of the issue, whereas "length" refers to its duration. For example, use "scope of the problem" instead of "length of the problem" if you are discussing the multifaceted nature of the issue, not how long it has persisted.
