In Jakob's story about a team of people working on interplanetary travel, it would be appropriate to use plural pronouns such as "they," "them," and "their" when referring to the team. This is because the team consists of multiple individuals working collaboratively, and plural pronouns clearly indicate that the actions or qualities being described pertain to the entire group.
For example:
- "They conducted experiments daily."
- "Their research showed promising results."
Using plural pronouns helps to emphasize the collective effort and unity of the team, which is likely a central theme in Jakob's story. It also avoids confusion that might arise from using singular pronouns, which could imply that only one person is involved. Overall, "they," "them," and "their" would be the best pronouns to reflect the teamwork and collaboration inherent in the narrative.
