Here's the classification of each choice:
Ineffective:
- ends sentences with a rising tone (This can indicate uncertainty or a question rather than a statement.)
- using filler statements such as “like” or “I mean” (These can distract from the message and make the speaker appear less confident.)
Effective:
- speaks in declarative sentences (This conveys confidence and clarity in the message.)
- shifting gaze across the audience while speaking (This engages the audience and makes the presentation feel more inclusive.)
