"I have worked at the Arizona Humane Society for ten years, and have seen the effects of the failure to spay and neuter your pets first hand" is an example of what part of an effective introduction?

Establishing your credibility to speak on the topic

Explanation:

The first part of an introduction when giving a speech or lecture is to establish your credibility to speak on that topic. This is important to get your audiences attention, it could be achieved by talking lightly about your credentials and experiences in that field. The statement "I have worked at the Arizona Humane Society for ten years, and have seen the effects of the failure to spay and neuter your pets first hand" is the speaker establishing his/her credibility to speak on the topic.

well it depends i think people around the world are coming around to gay marriage. but if you are talking abortion then wow, so much to talk about. such as men thinking they have the right to choose if women can, the fact there are health concerns if the women can't get one, and many more arguments to discuss. so i would definitely say abortion would be a much more interesting topic.
