The discussion technique that Jennifer uses most clearly in this conversation is, challenging assumptions.
When we want to give a discussion a different approach, we use this technique through What if... questions, it is necessary to present another alternative to respond to things that we already established.
The other techniques are very different from this one, promoting participation would be mostly used by a moderator not a regular participant in the conversation, MAking an objective is to land the discussion into something real, and Asking for rhetorical questions does expect any kind of answer which we do have in here, therefore the other three options are incorrect.
Dewey Decimal is library classification system. It helps to locate books in the library appropriately in order to generate topics by creating library classification system. The Classification helps to organize library materials by field of study. Main divisions are philosophy, social sciences, science, technology, and history. The system is made up of ten classes, each of them divided into ten divisions and which each one has got ten sections. Using Arabic numbers, three whole numbers makes the main classes. Then following numbers make sub-classes and further divisions. The classification is hierarchical and the same hierarchy is used for the system.
