Summary
The researcher says that hearing only one person in a conversation makes listeners constantly try to guess what the unheard person is saying. This makes it distracting to overhear one side of a cell-phone conversation. Cell-phone conversations are also distracting because people talking on a cell-phone are abnormally loud.

The risk that █ ██████ ████ █████ ██ ████████ ██ █████████ ████ ███ ██████ ██ ███████ ██ █ ████ ██████
This answer is unsupported. We don’t know whether actually having a cell-phone conversation is distracting. The researcher only discusses the effects of overhearing someone else's conversation.

When a driver █████ █ █████████ ██ ███ ████████ ███████ ███████ ██ █ ████ ██████ ████ ████████ ████ ███ ████████ ████████████
This answer is strongly supported. Hearing only one side of a conversation distracts a person from whatever they’re doing, as does the abnormally loud speech of someone talking on a cell-phone. Being distracted reasonably detracts from someone's driving.

Overhearing one side ██ █ ████████████ ██ █ ███████████ █████████ ████ ███ ██████ ██████████ █████████ ████ █████ ██ █████
This answer is anti-supported. The researcher says that overhearing just one side of a conversation is distracting. This is presumably true of traditional phones as well as cell-phones.

This answer is unsupported. We don’t know if these people always lose track of their own thoughts, we just know that they become distracted.
