Question

Which example below typifies frozen usage? the president holding a press conference a mother speaking to the principal an employee conducting business a technical manual explaining how to operate a toaster

Answer 1

The correct answer is: A technical manual explaining how to operate a toaster.

Here we use the definition of "frozen" related to the lack of emotions, affection or warmth. A technical manual gives direct  and clear instructions to do something, in this case how to operate a toaster. Therefore no emotions are needed as it is not trying to persuade anyone or make a point. Technical manuals try to give those instructions in the simpler way they can, this to avoid confusion or ambiguity.

In the other options the speaker has a direct contact with an audience, he needs to show a connection between them by using some kind of emotion.
