Expert writing Tips
Best practice

For instance, "The artist's style which fluctuates between realism and abstraction" is clear, but "The artist's style which fluctuates between painting and eating" is nonsensical.
Common error
Avoid using "which fluctuates between" in restrictive clauses where the information is essential to the meaning of the sentence. 'That fluctuates between' is often more appropriate when the clause defines or limits the noun it modifies. For example, use 'the temperature that fluctuates between' instead of 'the temperature, which fluctuates between', when you mean to identify a specific fluctuating temperature
