Answer 2

Religion, because tone, clarity, and organisation can influence the effectiveness of the delivery of a speech.
If one uses a sad or solemn tone during a speech of happiness, the effectiveness will decrease. If there is no clarity or organisation, the topic may be lost. Religion does not contribute to the effectiveness of the delivery of a speech, because different ethnic backgrounds should not affect performance.
