Answer 1

d. secondary sources​

Step-by-step explanation:

Information can be defined as processed data that can be used to perform specific tasks or job functions. The two (2) main sources of information are;

I. Primary source: this type of source comprises of raw information that are first-hand in nature i.e a personal experience or witness of an event (occurrence).

II. Secondary source: this type of source relies solely on the primary source for its information and as such it comprises of second-hand information provided by other authors or researchers.

Hence, secondary sources are the set of information written about a president by authors who did not personally witness an event or occurrence with respect to the president.
