Final answer:
In crafting a research memo, include 8-10 sources for a comprehensive but concise analysis. Utilize primary and secondary sources, cite correctly, consider counterarguments deeply rather than superficially, and stay adaptable to the topic needs.
Step-by-step explanation:
The general rule for how many authorities a research memo should discuss does not have a fixed number, but it should be thorough enough to cover the topic comprehensively without being repetitive or overly extensive.
A well-balanced memo should include 8-10 sources, comprising a mixture of primary and secondary sources. These can be both print and digital, and should be documented in either MLA or APA format, with in-text and end-of-text citations.
Make sure to present your research formally, indicating the full references for the material discussed, including any images researched.
Additionally, when authoring a research memo or paper, it is important to carefully consider and include evidence to support your claims, preferably one quote or paraphrase per paragraph, followed by 2-3 sentences of analysis.
It is also crucial to consider counterarguments, but instead of listing many in a superficial way, consider one or two in depth to create a more persuasive argument.
Always remember to be flexible in your approach and tailor your research and the number of authorities cited to the requirements of the topic and the guidelines provided by your instructor.
