Question

which of the following makes best use of a signal phrase and parenthetical citation? roberto leon writes, \more evidence is needed to confirm the findings\ (17). on page 17 it says, \more evidence is needed to confirm the findings\ (leon). the author states, \more evidence is needed to confirm the findings\ (17). roberto leon states, \more evidence is needed to confirm the findings\ (leon 17).

Explanation:

A strong signal phrase clearly identifies the author, and the parenthetical citation should only include missing key info (here, page number, since the author is named in the signal phrase). The first option uses a clear signal phrase with the full author name, and the parenthetical only includes the necessary page number, avoiding redundant author info in the citation. Other options either use vague signal phrases, redundant parenthetical info, or incomplete identifiers.

Answer:

A. Roberto Leon writes, "More evidence is needed to confirm the findings" (17).
