Term explanation
Closed questions are questions that can be answered with a limited set of responses — most commonly a simple 'yes' or 'no', or a selection from predefined options. They are used to gather specific, factual information quickly and efficiently. In presentations and training settings, closed questions are useful for gauging audience understanding, confirming agreement, or running quick polls. While efficient, they offer little depth and should be balanced with open-ended questions when richer feedback or discussion is needed.
LIZ AI helps structure presentations around the questions that matter. The Smart Presentation Composer frames content with clear, focused messaging — making it easier for audiences to follow arguments and reach conclusions.

It combines the instant-launch behavior of .ppsx files with the automation capabilities of macro-enabled formats. This makes .ppsm files useful for interactive or automated presentations, though they carry the same security considerations as other macro-enabled Office formats.
Learn moreA solution presentation is a structured pitch in which a presenter proposes a specific product, service, or approach to address a client's problem or business challenge. It typically frames the customer's pain point first, then presents the proposed solution and its benefits, supported by evidence or case studies. Solution presentations are central to B2B sales processes and consulting engagements, where building relevance and credibility is critical to winning the deal.
Learn moreA personal response system (PRS) — also called an audience response system or clicker system — allows individual participants to respond to questions or vote in polls during a presentation or class. Each participant uses a handheld device or smartphone to submit their answer, and results are aggregated and displayed instantly. PRS technology is used in lectures, corporate training, and conferences to increase participation, gauge understanding, and make sessions more interactive.

A typical blended model might include in-person workshops supported by e-learning modules, video content, or discussion boards that learners engage with before or after class. Blended learning gives instructors flexibility to use classroom time for higher-order activities while delegating knowledge transfer to self-paced digital content, improving both efficiency and learner outcomes.
