Answer:
1. Identify sources. - Include the person's name, credentials and accomplishments.
2. Cite qualified authorities. - The testimony should match the person's credentials.
3. Cite well-respected authorities. - Endorsements by famous people grab attention.
4. Cite testimonies accurately. - Avoid taking quotes out of context.
Step-by-step explanation:
We use testimonies to support an argument or to show evidence of a claim we are making. These are important ¿in any scientific or academic writing, since we want to don't know everything and we need to use work from previous authors to support our arguments, while giving credit where credit is due. We need to identify our sources first: who are they and why is their testimony relevant to us. Then we need to make sure there is match between their qualifications and the information we quote. Not doing this might hurt our case rather than help, since one person might be an expert in one field but when quoted in a different one, their testimony might have wrong or inaccurate facts. Afterwards, if possible, we should go for well-respected authorities, who have earned their status through their work and achievements and thus have a relevant testimony to give. Finally, make sure the testimonies are not taken out of context so they are not misunderstood and they actually help us make our case stronger.
