According to Chapter $9($Foster Collaboration$)$ from The Leadership Challenge, which of the following was not discussed relating to face$-$to$-$face interactions?

Group of answer choices

Research shows a significant link to profitability and a high degree of face$-$to$-$face interactions in service industries, but no such connection in manufacturing industries.

There are limits to "virtual trust" $($e$.$g$.,$ e$-$mails, texting, videoconferencing, etc.$).$ Firsthand experience with another human being is just a more reliable way of creating identification, increasing adaptability, and reducing misunderstandings.

People can act as a cohesive unit only when they have some amount of face time with each other.

People who expect durable, frequent face$-$to$-$face interactions in the future are more likely to cooperate in the present.
