Answer:
C: According to [author’s name]
Step-by-step explanation:
A signal phrase is used to introduce a quote from a source in your writing. It helps to attribute the information to the original author and makes it clear that you are quoting someone else's words. For example, if you are writing a research paper and want to include a quote from an article written by John Smith, you could use the signal phrase "According to John Smith..." before the quote. This signals to the reader that the following words are not your own, but rather a direct quote from John Smith's article. Option A, "If you ask me...", is not a signal phrase because it does not indicate that the words following it are a quote from a specific source. Option C, "[Author's name] is a good writer...", is not a signal phrase either, as it does not introduce a quote from the source. Option D, "To summarize...", is also not a signal phrase because it does not attribute the information to a specific author or source. In summary, when quoting from a source in your own writing, it is best to use a signal phrase like "According to [author's name] ..." to properly attribute the information to the original author.
