Expert writing Tips

Best practice

Always use the correct tense and form of verbs. "Investigate" requires a helping verb such as "are" to be in the progressive form (e.g., "are investigating") to denote an ongoing action.

Common error

Avoid using the base form of the verb "investigate" directly after "are". Ensure you use the correct progressive form, which is "investigating".
