Answer:
I think Rico will consult a number of websites because his librarian provided a list.
Explanation:
Given the fact that Rico had a 'B' in his last research which he did with an online encyclopedia, and the reason why he did not make an 'A', according to his teacher was that the online encyclopedia, "was not sufficient research", Rico would most likely avoid this resource now.
To make an A in his Social Studies assignment, Rico would consult the list of websites provided by the librarian because, then, he would be making sufficient research.
