Directions: In the sentence below, the underlined part may contain an error. Choose the option that correctly replaces it. If no correction is needed, select “No improvement required.”

The members of the research team are constantly communicated with each other.

The correct option is constantly communicating with.

Step-by-step Explanation:

1. Identify the subject and voice:
The subject of the sentence is "The members of the research team." Since the members are actively performing the action of interaction among themselves, the sentence requires the active voice.

2. Analyze the error in the original phrase:
The given phrase "are constantly communicated with" uses the past participle form ("communicated"), which creates a passive voice structure. This incorrectly implies that an outside force is communicating to or about the team members, rather than the members speaking with one another.

3. Use the present continuous tense:
To express an ongoing action performed actively by the subject, we use the present continuous tense structure: be + present participle (-ing). Thus, "communicated" should be replaced with "communicating" to form "are constantly communicating."

4. Verify the preposition:
The verb "communicating" pairs naturally with the preposition "with" to denote reciprocal interaction ("communicating with each other").

Therefore, the corrected sentence reads:
"The members of the research team are constantly communicating with each other."
