Answer:
tapping on the podium with the fist
Explanation:
Body gestures such as "tapping on the podium with the fist" are often used by good speakers to help make their points and to keep the audience engaged.
This is because "tapping on the podium with the fist" gives a sound like exclamation that drives home a point that tends to show the power and confidence on the part of the speaker.
Option B: rapidly tapping one foot on the floor: shows impatience or releasing of tension. Hence, this is not correct.
Option C. making a hand movement for the listener to come towards the speaker: is a means of asking someone to come forward only, not necessarily to express or give credence to a point. Hence, this is not correct as well.
I am not sure which poem you are referring to here, but one poetical technique is called enjambment. This occurs when a line continues to the next line without a pause. Even if there is a stanza break in between, the lines are meant to be read continuously. For example, consider these lines from a poem by William Wordsworth called Beauteous Evening:
"The holy time is quiet as a Nun
Breathless with adoration; the broad sun
Is sinking down in its tranquility"
Here, Wordsworth is not intending that you pause after you read "Nun" or "sun." He wants you to read these lines as a continuous sentence or thought. Hope this helps.
