Here's the evaluation of each choice:
-
Ends sentences with a rising tone: Ineffective
This often creates confusion and can make statements sound like questions, rather than asserting information. -
Speaks in declarative sentences: Effective
Declarative sentences convey clear and confident statements, which are more engaging and easier for the audience to understand. -
Shifting gaze across the audience while speaking: Effective
Making eye contact and shifting gaze can help engage the audience and create a connection, making the presentation seem more personal and interactive. -
Using filler statements such as “like” or “I mean”: Ineffective
Filler words can distract from the message, reduce clarity, and suggest a lack of confidence or preparation.
So, to summarize:
- Ineffective: ends sentences with a rising tone, using filler statements such as “like” or “I mean”
- Effective: speaks in declarative sentences, shifting gaze across the audience while speaking
